FAQs

If your system is currently running a schedule, iComfort^® could start working earlier than expected to achieve the desired temperature at the specified time in the schedule that is currently running. When this occurs, the "Transitioning To Next Schedule" status message appears in the left side of the home screen.

With Smart Away you’ll never have to remember to put your home in Away Mode when you leave your house or remember to adjust your thermostat temperature when you return home. This means you’ll always be comfortable and saving energy when you’re away.

The Smart Away feature relies on the iComfort^® S30 Mobile App running on your mobile device (smart phone or tablet).

Smart Away works for any user in the home that has a mobile phone/tablet with Global Positioning System (GPS) and a data plan by setting geofences around the home. You can specify your Smart Away settings such as away fence and away set-points in the iComfort^® S30 Mobile App under menu > settings > away.

Smart Away can only be enabled if you have an iComfort^® S30 account and you’re signed-in on your thermostat.

Smart Away works with multiple users in the same household, as long as they have a smart phone/tablet and participate is turned on.

A geofence is a geographical boundary around the home.

Does it work with multiple people in the house?

Yes, it can support multiple smart phone users living in the same house. The thermostat will listen to geofence changes from all the smart phones and determine the set-points for the home based on each user's approximate location (or geofence) and Smart Away settings.

We recommend that you allow your dealer to have remote access to your system, this way your dealer is able to quickly troubleshoot any issues, alerts, or warnings that may occur remotely. However, you do have the ability to limit the level of access from full control to view-only privileges.


To edit your dealer access go to menu > settings > general > dealer info > dealer access.






What is the difference between Remote View, Remote Access and Alerts and Notifications?


1) Remote View: Allows your dealer to remotely view the status of your system.

2)Remote Access: When off is selected, your dealer will not have authorization to troubleshoot your system remotely. If you have "On/Always" selected, you’re giving authorization to your dealer to troubleshoot your system remotely at any time (On/Always is selected by default).

3) Alerts and Notifications: Allows your dealer to be notified when your system needs maintenance and when critical alerts and warnings occur (your dealer does not get reminders, for example for replacing the filter, or other informational messages you may receive).

1) From the home screen, tap the “Modes/Schedules” button.

1) From the home screen, tap the “Modes/Schedules” button.




2) In the select modes screen, tap “Schedules” and then tap the "Edit Schedules" button.




3) In the edit schedules screen, you can select which schedule you would like to edit. You can customize heat and cool set points, period times, system mode, and fan mode in traditional schedules (not Schedule IQ).




Why and how is Schedule IQ different than winter, summer, spring/fall, and save energy schedules?

Schedule IQ is a smart schedule that uses Smart Away along with traditional scheduling for when you’re at home during the day and night. The other schedules (winter, summer, etc.) are traditional schedules in which you can set up to four periods and their corresponding set-points. They come pre-loaded with recommended settings for the season (winter, summer, spring/fall) or for saving energy (save energy schedule).


Are schedule changes applied to other systems?

No, for example, you may have two systems in your home, one for upstairs and one for downstairs. If so, then each system has its own settings and its own schedules. For example, if you edit "Winter" schedule in system "Upstairs", and you would like to apply the same change for system “Downstairs”, you would need to edit “Winter” schedule for system “Downstairs” too (via modes/schedules > schedules > edit schedules). You would also need to make sure to select “Winter” schedule under modes/schedules > schedules for each of the systems. However, if you have iHarmony zoning, a change in a schedule for a system does apply to all other zones in that same system. But you also need to make sure that each zone has the mode/schedule you desire selected.

1) From the home screen, tap the “Modes/Schedules” button.




2) In the select modes screen, select “Schedules” and within the fly out popup press "Edit Schedules".




3) Once in the edit schedules screen, you’re able to select the schedule you would like to modify. For traditional schedules (summer, winter, spring/fall, and save energy), you can customize the days, time periods, set-points for each time period, and also select a system mode, and fan mode (optional). You’re allowed up to 4 periods in one day.




You can also rename traditional schedules and restore them to their factory default settings. For example, the save energy schedule comes preloaded with recommended set-points for saving energy, but because of differences in geographic regions, these settings may not be the most optimal for your area, and thus we allow you to modify them. If you would like to see what the default set-points were at the time of purchase, then you can tap "Restore".

The outdoor temperature displayed in your thermostat's home screen can come either from the sensor in your outdoor unit or from https://www.accuweather.com/. You can choose between these two sources under menu > settings > display > outdoor temperature source.

When the AccuWeather option is selected, your iComfort^® S30 must be connected to Wi-Fi.

Defrosting happens when the temperature outside gets too cold, or if there is ice and the system cannot use the heat pump (if your system has a heat pump). To get rid of frost, the system will run a mode similar to AC to take the heat from inside the house across the indoor coil and transfer it outside to warm the outdoor unit. The goal is to heat the outdoor unit to evaporate the water.

The weather forecast on the weather screen on your thermostat (and mobile app and iComfort^® S30 web portal) comes from https://www.accuweather.com/.


To view the weather forecast in your area and current outdoor air quality conditions, simply tap on the weather icon in the home screen.

Just like in a weather report, the Feels Like temperature is the temperature you feel right now, which may actually be different than the current temperature. The Feels Like feature is a combination of outdoor and indoor temperatures and indoor humidity to determine what it actually feels like in the home. When Feels Like is turned on, your iComfort^® S30 will display this temperature.


Also, when Feels Like is turned on and you change the temperature set-point, you’re specifying what temperature you would like your house to feel at.


Feels Like comes enabled by default. To turn it off, go to menu > settings > Feels Like.

Away Mode is a special mode for when you’re away or nobody is home. When Away is active, the home screen brightness dims and it allows you to specify a heat set-point and a cool set-point that will be used when you’re not at home. You can also change the Away set-points at any time under menu > settings > away.


To use Away Mode, you manually put your system in Away Mode when you leave your house by tapping the Away button on the home screen on your thermostat (bottom left). The Away button is also available in the mobile app and web portal in the “my homes” screen. When you return home, you’ll need to cancel Away Mode.



(home in away)



Alternatively, if you have a smart phone, you can enable Smart Away so you’ll never have to manually put your home in Away Mode when you leave your house and remember to adjust your thermostat temperature when you return home. This means you’ll always be comfortable and saving energy when you’re away.

Do you like your home to always be at the same temperature no matter what? Then Perfect Temp. is for you. Perfect Temp. is a feature that uses auto mode (a special heat/cool mode) with advanced algorithms to control the humidity and fan so your home is always at the same temperature.


Also, when it is spring or fall and you don’t know whether your system should be cooling or heating, Perfect Temp. allows you to set only one set-point instead of two (for heating and cooling).



Perfect Temp. comes disabled by default. To turn it on, go to menu > settings > heat & cool. We recommend you try it!




What are the advantages of Perfect Temp.?

Perfect Temp. lets you set your home at your ideal temperature, and your system automatically adjusts heating and cooling to maintain that setting.

Perfect Temp. also works with Schedule IQ, so your home can be set at your ideal away temperature set-point when you’re away.

Perfect Temp. will save your home energy usage, with a feature called “coasting”, which allows the current temperature to reach the desired single set-point without the system doing any work based on monitoring current outdoor weather conditions.

Schedule IQ is a smart schedule that works with Smart Away. With Smart Away, you’ll never have to put your home in Away Mode when you leave your house or remember to adjust your thermostat temperature when you come home. With Schedule IQ selected, it will automatically change set points according to your geofence and Away settings. Schedule IQ also allows you to combine Smart Away with the flexibility of traditional scheduling by setting “At Home Day” and “At Home Night” set-points and times.



To access and edit Schedule IQ, go to modes/schedules > schedules > edit schedules > Schedule IQ.

Yes, your iComfort^® S30 will dehumidify, humidify or do both according to your humidity settings and equipment installed. Your iComfort^® system humidity settings are located under menu > settings > humidity. Depending on your equipment, you may have different humidification and/or dehumidification options available.

Yes, you can control the range of temperatures you set your home to by going to menu > settings > heat & cool and turning on “wider set-point range”.

It depends on your equipment configuration, if you have iHarmony zoning, and how many zones/sensors you have purchased.You can learn more and purchase iHarmony zoning here: http://www.lennox.com/products/comfort-controls/iharmony/

When you have a schedule selected, if you make manual changes to the temperature set-points, you’ll see a message about the schedule being in “Hold” since you have manually overwritten the schedule set-point(s). You can customize the duration of the “Hold”, but by default the schedule is on hold until the next period. After a “Hold” is set, you can choose to “Cancel” the schedule hold, which will resume the schedule to normal operation.

In menu > settings > notifications > reminders, you're given two options: "Calendar" and "Run-Time". Let’s say you have “Filter 1 Reminder” set to 3 months. With “Calendar Time”, it will take 3 months regardless whether the system is running or not for the reminder to show. With “Run-Time”, it will take 3 months of the system running (which may be longer than 3 calendar months) for the reminder to show.

It depends on the equipment you have in your home. You may have purchased a humidifier or a dehumidifier or you may have both. The humidity options available to you are located under menu > settings > humidity. Below is a summary of the humidity options and what they do:

Humidification
Normal - Recommended for moderate climates. Runs the humidifier when there is a call for heat and humidification.

Max - Recommended for drier climates. Runs the humidifier when there is a call for humidification only.

Dew Point - Automatically changes the humidity set-point to try and prevent condensation on the windows.

Dehumidification
Normal - Recommended for moderate climates. Dehumidifies when there is a call for cooling and dehumidification.

Max - Recommended for humid climates. Dehumidifies when there is a call for dehumidification only. May cool beyond desired set-point by 2 degrees.

Climate IQ© - Monitors current climate conditions and automatically removes excess humidity when necessary.

The Smart Hub is a system and network controller. It has the ability to connect to other iComfort^® S30 devices running Lennox software to create a special Lennoxmanaged local network. A Lennox-managed local network is independent of the actual physical network it is running on, and it can operate over the home Wi-Fi network or over the Smart Hub Wi-Fi network.

It is typically located near the indoor unit. This could be in your attic, basement or garage. Below is an example image of what a Smart Hub looks like.

You can restart the Smart Hub by pressing and holding the center Lennox button for more than 5 seconds.

Having a lock icon on your thermostat means you’re restricted from certain features. There are two types of lock screens: "Partially" locked and fully "Locked".

Partially locked means you’re only able to edit and change set-points. You’re restricted from changing anything in settings and changing the system mode / schedule (screen 1).

Locked means you’re only able to view the set-point(s) and indoor temperature in every zone but not able to edit or change any settings (screen 2).

Your fan mode options are located in the modes/schedules screen on the top right. Pressing the fan icon will allow you to manually control the fan mode. The modes available are: On, Auto and Circulate. Your fan button may look disabled or grayed-out, if so, you can tap on it and a pop-up will display explaining why (it may be due to Allergen Defender or Perfect Temp. features being turned on).

In your thermostat, go to menu > settings > account to change your account information such as name, billing address, email address, password and other settings. In your mobile app or web portal, you can tap/click on your email address on the top right and then “View Account”.

iComfort^® S30

A system corresponds to the outdoor/indoor unit combo. Let’s say that you have two outdoor units. This means you have two systems. If you have purchased iHarmony zoning, then you’ll be able to control the temperature in certain areas or rooms of the house, also called zones, with the same system.

Below is a diagram showing a house with 2 systems, with each system controlling an area of the home. One system controls all rooms upstairs while the other system controls all rooms downstairs.



Diagram 2 below shows a home with one system and iHarmony zoning. You can control the temperature for each individual room in the house even though they share the same system. iHarmony zoning requires additional equipment (automated dampers).

In your thermostat, you can go to menu > settings > display. Display settings are only available in the iComfort^® S30 display and not in the mobile app or web portal. The distance range for the proximity sensor is short, approximately 25 cm or up to an arm’s length. The proximity sensor is used to automatically wake up the display when you approach it when the screen saver is turned on.

The distance range for the proximity sensor is short, approximately 25 cm or up to an arm’s length.

You can change or set your home location under menu > settings > home info. Having the correct home location is important because your weather information, screen saver weather background (if you have this feature enabled) and mobile app/web portal show current weather information outside the home

When you create an iComfort^® S30 account, you’re asked to check a box if you wish to receive email updates, meaning alerts and reminders via email. You can always change this setting again under menu > settings > account > account info in the thermostat.

In your thermostat, go to menu > settings > account to change your account information such as name, billing address, email address, password and other settings. In your mobile app or web portal, you can tap/click on your email address on the top right and then “View Account”.

You can go to menu > settings > humidity to modify the dehumidification and/or humidification set-point(s) in your home. The slider allows you to adjust the desired percentage of humidity inside the home. The shaded/darker areas in the slider represent the allowable range of values for humidification and dehumidification.

At outdoor temperatures above the high balance point, only the heat pump is allowed to run. At outdoor temperatures below the low balance point, only the auxiliary heat source is allowed to run. At outdoor temperatures between the high and low balance points, both the heat pump and auxiliary heat source are allowed to run. You can modify the high and low balance points under menu > settings > heat & cool > auxiliary heat.

In your thermostat menu > settings > display > screen saver there are the following options available: Off (display is always on), Weather (display a background corresponding to the current outdoor weather if weather information is available and your thermostat is connected to Wi-Fi), Power Save (the screen turns off to save power - useful if the thermostat is in your bedroom and you don’t want it to bother you at night) and Picture (you can upload a picture using your mobile app or via the web portal).

Under menu > settings > home info, there is the Remove Home button. You would use this button to remove all the thermostats in the home from your account.

To change the temperature scale, in your thermostat, go to menu > settings > display > temperature scale. Display settings are only available on your thermostat settings (and not the mobile app or web portal).

In your thermostat, mobile app or web portal, you can go to menu > settings > general > language to choose between English, French, or Spanish. These are the only languages supported at this time.

A zone corresponds to an area or room of your house where you can independently control the temperature from other zones. A zone maps 1:1 to a system or an iHarmony zone.

In the thermostat, mobile, or web portal, on the home screen you can swipe left or right to navigate zones/systems. You can also tap on the zone name above the temperature control (a.k.a., horseshoe) to see a pop-up with the list of zones (or systems) in your home.

A system corresponds to the outdoor/indoor unit combo. Let’s say that you have two outdoor units, this means you have two systems. If you don’t have iHarmony zoning to control the temperature in every room of the house, then the two systems will appear as two zones on your thermostat's display, and the system name will appear above the temperature set-point control (a.k.a., horseshoe) on the home screen.

You can change your system name in your thermostat under menu > settings > system.

You can change the home name and address in your thermostat, mobile app, or web portal, under menu > settings > home info.

Date and time typically come from Lennox if your thermostat is connected to Wi-Fi. If your thermostat is not connected to Wi-Fi, then you can set the date and time manually by going into your thermostat to menu > settings > general > date & time.

You can change your thermostat’s display settings from the thermostat under menu > settings > display. Display settings are only available in the display itself and they are not available on the web portal or mobile app.

The zone name can be changed by tapping the zone name and then tapping the pencil icon (edit) next to “Zones”. Alternatively, you can change the zone name under menu > settings > iHarmony zoning and choosing the zone you would like to rename.

You can go in your thermostat, mobile app, or web portal, to menu > settings > general > dealer info > dealer access to set the level of access you wish to grant to your dealer.

This is a fan mode that you can choose in the modes/schedules screen. When enabled, the fan automatically kicks in when the system detects high levels of allergens in the air. When Allergen Defender is working, you’ll see a status message on the home screen saying “Allergen Defender is working”.

This is an internal safety feature that prevents the unit from running when it detects it is too cold outside to run. When this occurs, you’ll see a status message on the home screen that says “Ambient Lockout”.

When Perfect Temp. is turned on, coasting allows the current temperature to reach the desired single set-point without the system doing any work based on the current outdoor temperature. When coasting, you’ll see a status message on the home screen, with either a blue down arrow (when current temperature is greater than desired set-point) or an up red arrow (when current temperature is less than desired set-point).

Auxiliary heat is electric resistance heat. Under menu > settings > heat & cool, you can turn on auxiliary heat so that you can specify the low and high balance points of when you would like the auxiliary heat to kick-in.

Emergency heat is when you use your supplemental heat (2nd stage) by itself, without the use of your heat pump (1st stage heat). This option is not available for non-heat pump systems.

Auxiliary heat (only on heat pump systems) is when the 1st stage heating equipment cannot keep up with the space heating demand and a 2nd stage call for additional heat is required. With an Air Handler with electrical heat, when 2nd stage runs it will run in conjunction with 1st stage. With Dual fuel when 2nd stage runs, it will turn off 1st stage heating and run only on 2nd stage.

If your AUX lockout temp is 40°F/4.4°C, then auxiliary heat will come on when the outdoor air temperature drops below 40°F/4.4°C. With Heat Pump Balance, you don't have to worry about the AUX lockout temperature.

Climate IQ monitors current climate conditions and automatically removes excess humidity when necessary. Climate IQ works with all Lennox outdoor communicating equipment. This includes the: XC/XP25, XC/XP21, XC/XP20, XC/XP18, XC/XP17 units. To find Climate IQ go to settings > humidity > Climate IQ.

Dew Point is a humidity setting under menu > settings > humidity to automatically change the humidity set-point to try to and prevent condensation on the windows. Dew Point adjustment mode will change the humidification set point based on the outdoor temperature and your user-defined dew point adjustment setting.

All heat pumps operating in northern climates (below 35°F) normally need a supplemental heating source. Usually this is in the form of electric heating provided by the indoor unit. Other sources could be gas, oil, or hot-water back-up systems as well. The supplemental heat is also referred to as "second-stage" or "back-up" heating, with "first-stage" being the heat pump only. Emergency heat is when you use your supplemental heat (2nd stage) by itself, without the use of your heat pump (1st stage heat). The Emergency heat option is not available for non-heat pump systems.

If this feature available to you, you can find it and turn it on by going to modes/schedules > emerg. heat.

The iHarmony® zoning system allows you to change the temperature throughout the house or change it in specific areas or rooms of the house. To learn more about and purchase iHarmony zoning, go to: http://www.lennox.com/products/comfort-controls/iharmony/

You may see a status message on the thermostat home screen that says “Load Shedding”. This means that your energy company has interrupted or is affecting the supply of electricity in your area or home to reduce the demand on the power grid. The duration of load shedding depends on your region, your energy company and your service contract.

When you’re moving out of your home, you can remove the iComfort^® S30 thermostat(s) in your home from your account and sign-out of the thermostat all at once with the move out button under menu > settings > account. If you’re the new homeowner, you can still “Move Out” the old homeowner so that you can create your own iComfort^® S30 account. Having an iComfort^® S30 account allows you to control your thermostat remotely from the web portal and mobile app and it also allows you to utilize other advanced features of your iComfort^® S30 Smart Thermostat such as Smart Away and Schedule IQ.

iComfort^® S30 alerts you if the house gets too cold or too hot, so you have a chance to do something about it. You can set the minimum and maximum temperatures the house must reach for you to get notified under menu > settings > heat & cool > safety protection.

Yes, just make sure to turn on the safety protection feature under menu > settings > heat & cool.

When a schedule is selected, the home screen indicates which schedule is running. In this mode, changing a temperature set-point by pressing on a knob or set point below will cause you to overwrite the current schedule settings. Therefore, a prompt dialog will appear asking you for how long to overwrite the schedule. You can select 1 hour, 2 hours, 8 hours, 24 hours or a Custom option. If you select Custom, a time/date appears and you have the option of setting the hold for any length of time. After a hold is set, the dialog disappears and a “Schedule Hold” status message will appear on the home screen along with a cancel option should you choose to revert back to the schedule.

You can add a new iComfort^® S30 Smart Thermostat to your account by simply logging into the new thermostat with your existing account. Alternatively, you can add your new iComfort^® S30 Smart Thermostat to your account by using the web portal or mobile app, by entering a pin you generate on the thermostat.

To generate the pin, go to your thermostat, then go to settings > account and at the bottom of the page press the "Generate Pin" button. You’ll be given a number that is unique for a one-time use.

When you enter the pin on the web portal or mobile app, you’ll be automatically signed-in on your thermostat.





Steps to entering the pin on a mobile platform:

1. Press the thermostat icon with “+” button and your will enter the "Add iComfort^®" screen.
2. Enter the pin generated on the thermostat and then tap the "Add" button.
3. Lastly, choose an existing home if you already have one or tap the "Add New Home" to enter a new home.

Yes, by default, iComfort^® reminds you when it is time to replace the filter, humidifier pad, UV bulb, or when it is time for maintenance. Your dealer configured these reminders for you during installation, but you can always modify the reminder settings for how often you want to be reminded under menu > settings > notifications in the reminders section.





Here is an example of how you receive a reminder. You can choose to be reminded later if you have not yet changed your filter, for example.

Your thermostat maintains comfort by automatically adjusting how hard your HVAC system works and for how long it operates. Your monthly summary report displays the average demand for each component in your system.
Demand is a number from 0 – 100%, where 100% is the maximum heating or cooling your system can provide. For example, a system running at 50% cooling demand is delivering half of its maximum cooling capacity. Demand provides better insight than runtime alone because it factors in what level of heating or cooling the system was operating. This is important for multistage and variable capacity systems that use multiple levels of heating or cooling. Using lower levels of heating or cooling can result in longer runtimes, but it is more efficient. ? Heating demand can usually increase as the outdoor temperature drops. As you transition from fall into winter, you will typically see your heating demand increase. Similarly, in the spring heating demand will typically decrease as the weather warms up. Your report includes the average outdoor temperature for each month, enabling you to compare your change in heating demand to the change in temperature.

Cooling demand will typically increase as the outdoor temperature increases. Cooling demand will usually be the highest in the peak of Summer and drop off as temperatures decrease.

Single Stage
Single stage systems have only one operating capacity, on at 100%. Therefore the thermostat simply adjusts demand by changing runtime.

Two Stage
Two stage systems have two operating stages. The thermostat will first attempt to maintain comfort by operating only the lower stage. When the system cannot maintain comfort with the lower stage, it will begin to operate the higher stage.

Variable Capacity
Variable capacity systems continuously adjust the heating or cooling capacity from its minimum to its maximum capacity. The thermostat will maintain comfort by continuously adjusting the capacity of the system.

Electric Heat and Fan Demand calculations always assumes 100% capacity when on.

The performance report display on-demand performance data from your iComfort^® S30 system for the last 10 days. It is divided into 3 sections:

1. The all-in-one graph

2. The table below

3. The hide/show panel on the right

The graph displays the variables that are turned on in the hide/show panel. The table below the graph displays the details for the day/hour selected in the graph. In order to customize the data that you see, you can:

1. Select day or hour at the top

2. Choose which variables to display on the graph by turning them on/off on the hide/show panel

3. Move the knob to view a specific day / hour

The temperature and humidity values represent the average for the day / hour. When hour is selected, the system mode and fan mode are those at the beginning of the hour. If the hide/show panel is not displaying in your web browser view, you are instead getting the menu button on the top right. If you tap on it, the hide/show panel will display. This is because your window size is not wide enough.

What variables can I turn on/off in the hide/show panel?

The variables you can control depend on the equipment that you have installed and the current operation of your system. For example, only customers that have electric heat will see electric demand as a variable. Here is a list of all the possible variables for an iComfort^® S30 system:

If the system is having issues obtaining data for a variable, it is not displayed on the graph, and instead it shows in this panel with a warning icon.

Please refer to the related questions below for the meaning of "demand" and "runtime".

The monthly performance report contains a summary of how hard the system worked (runtime and demand) for the past month and compares it to the previous month. Please refer to the related questions below for the meaning of runtime and percent demand. The report also contains other helpful information such as how much time your system spent on away mode, your home's average indoor temp., the average outdoor temperature for your zip code, and when your next filter replacement is due.

When the thermostat screen is locked, the lock icon appears on the home screen. To unlock the screen, just press and hold the lock icon



Once your screen is unlocked, everything should return to normal and allow you to change set-points, mode, etc.



2: Tap Edit Schedule button on the Select modes screen

Settings are applied to an individual system. When you go to menu > settings, you’re viewing and changing the settings for that one system. You may have more than one system in your home, such as one for upstairs and one for downstairs. If so, you may need to change a particular setting for each system. These settings will then apply to all zones within that system.

The most basic step towards troubleshooting your system is to check for alerts or warnings that are currently active. Tap the menu button, and then select the notifications button to view them



Notifications are color coded to indicate their importance, with red being most critical, followed by orange and so on. After selecting the notification, write down the alert or warning code. You can check what it means here: What does this alert or notification mean?



If needed, you can contact your dealer (menu > settings > general > dealer info) or Lennox (at 1-800-9-LENNOX) to get any issue resolved as soon as possible.

1. In the thermostat, go to menu > settings > advanced settings, and press the reset button.



2. Press the “Restart Thermostat” button.

In the thermostat, go to menu > settings > general > about to view the Smart Hub software version and model number.

In the thermostat, go to menu > settings > general > about to view the thermostat software version and model number.

From the removed thermostat, login using your iComfort^® S30 credentials under menu > settings > account. Logging in will automatically add the iComfort^® S30 Smart Thermostat to your account again.

These are dealer only configuration settings screens in the thermostat. It is not recommended that you enter the dealer control center to view or modify HVAC settings unless you’re a dealer or trained professional technician.



What is the Dealer Control Center under Advanced Settings?



If you’re not a trained professional technician or authorized Lennox dealer and you modify “dealer only” advanced settings for your HVAC system, Lennox and your dealer are not responsible for any damage you may cause to your equipment as a result of any changes you may have done in the dealer control center.

The thermostat automatically checks for software updates every 24 hours for you. In case you just installed iComfort^® S30 and do not wish to wait for the automatic update, you can go to menu > settings > general > software update and tap the “check for updates now” button.

Runtime shows you how long your iComfort^® S30 equipment was in “On” mode. It does not take into account how hard your system worked (percent demand) which depends on whether you have a low efficiency 1-stage, mid efficiency 2-stage, or high efficiency variable capacity system and other factors. Runtime can be analogous to how much distance a car ran without accounting for its fuel efficiency. If you want to understand how efficiently your equipment ran see “How Hard Did the System Work? “

For furnace and A/C systems the following Runtime parameters are displayed

 1. Heating

 2. Cooling

 3. Fan

For Heat Pump (HP) and air-handler systems the following Runtime parameters are displayed

 1. Heat Pump + Electric Heat

 2. Electric Heat only

 3. Heat Pump Only

 4. Cooling

 5. Fan

A duel fuel system (Heat Pump with an indoor furnace unit) will have the following Parameters

 1. Heat Pump + Electric Heat

 2. Electric Heat only

 3. Heat Pump Only

 4. Heating

 5. Cooling

 6. Fan

When cooling or heating, the fan is running. Fan values runtime represent when the fan ran alone without heating or cooling. This includes when Fan circulation is manually set to “On” and when allergen defender is on.

Electric Heat only runtime includes time in defrost mode, Auxiliary heat, Emergency heat setting or if the heat pump is unavailable.

Most S30 thermostats operate with Lennox communicating equipment that sends serial communication regarding the Runtime.

You can view runtime information for your system in the web portal for iComfort^® S30 under menu >performance report, or in the monthly email performance report. In the web portal, you can select to view runtime according to a day (in the last 10 days) or a time in the last 24 hours. Runtime for a day is in hours, while runtime for an hour is in minutes. In the monthly report, you only get runtime values for the previous month.

Demand varies with the outdoor weather. As the weather becomes more extreme, you can expect your HVAC system demand to increase. Your use of your home can also cause demand to change. For example, having extra guests visiting could increase cooling or heating demand depending on your setting. Alternatively, going on vacation could reduce demand if you set your system to Away mode or if you are using Smart Away.

Here are some pointers to reduce cooling or heating demand in your iComfort^® S30 system:

1) When in cooling, raise your cooling set-point to the highest temperature which you can be comfortable. Program your thermostat to set the cooling set-point even higher when you will not be home. Similarly, when in heating, lower your heating set-point to the lowest temperature which you can be comfortable. Program your thermostat to set the heating set-point even lower when you will not be home. You can utilize the Smart Away feature on the iComfort^® S30 thermostat to do this automatically.

2) Change your filters.

3) Keep your doors and windows closed.

To stop receiving a monthly email containing the performance report of your iComfort^® S30 system, you can follow these steps:

On the web portal:

1. Log in to the iComfort^® S30 web portal.

2. Click on your account / email address at the top.

3. In the "account info" dialog, turn off "monthly performance report".

On the iComfort^® S30 Thermostat, you can go to menu > settings > account, scroll to the bottom of the screen and you should see the monthly performance report option.

Interruption in Wi-Fi connectivity or a faulty outdoor air sensor.

This error may be the result of a faulty outdoor temperature sensor (if installed) or interruptions in connectivity. If an outdoor air sensor is installed, check your thermostat display for the temperature reading or for error notifications. If there is no temperature displayed, contact your Dealer. If you do not have an outdoor air sensor, check your Wi-Fi connection.

The iComfort^® S30 Mobile App is available in the iTunes App Store and Google Play.

The iComfort app is compatible with Apple smart phones and tablets and Android smart phones and tablets.

The versions that are currently supported are:

• Latest iOS + the 2 previous versions
• Latest Android + the 3 previous versions

Older versions are available, however, they will not be supported and/or updated. You can use these versions at your own risk.

Runtime shows you how long your iComfort^® S30 equipment was in “On” mode. It does not take into account how hard your system worked (percent demand) which depends on whether you have a low efficiency 1-stage, mid efficiency 2-stage, or high efficiency variable capacity system and other factors. Runtime can be analogous to how much distance a car ran without accounting for its fuel efficiency. If you want to understand how efficiently your equipment ran see “How Hard Did the System Work? “

For furnace and A/C systems the following Runtime parameters are displayed

 1. Heating

 2. Cooling

 3. Fan

For Heat Pump (HP) and air-handler systems the following Runtime parameters are displayed

 1. Heat Pump + Electric Heat

 2. Electric Heat only

 3. Heat Pump Only

 4. Cooling

 5. Fan

A duel fuel system (Heat Pump with an indoor furnace unit) will have the following Parameters

 1. Heat Pump + Electric Heat

 2. Electric Heat only

 3. Heat Pump Only

 4. Heating

 5. Cooling

 6. Fan

When cooling or heating, the fan is running. Fan values runtime represent when the fan ran alone without heating or cooling. This includes when Fan circulation is manually set to “On” and when allergen defender is on.

Electric Heat only runtime includes time in defrost mode, Auxiliary heat, Emergency heat setting or if the heat pump is unavailable.

Most S30 thermostats operate with Lennox communicating equipment that sends serial communication regarding the Runtime.

You can view runtime information for your system in the web portal for iComfort^® S30 under menu >performance report, or in the monthly email performance report. In the web portal, you can select to view runtime according to a day (in the last 10 days) or a time in the last 24 hours. Runtime for a day is in hours, while runtime for an hour is in minutes. In the monthly report, you only get runtime values for the previous month.

Your thermostat maintains comfort by automatically adjusting how hard your HVAC system works and for how long it operates. Your monthly summary report displays the average demand for each component in your system.
Demand is a number from 0 – 100%, where 100% is the maximum heating or cooling your system can provide. For example, a system running at 50% cooling demand is delivering half of its maximum cooling capacity. Demand provides better insight than runtime alone because it factors in what level of heating or cooling the system was operating. This is important for multistage and variable capacity systems that use multiple levels of heating or cooling. Using lower levels of heating or cooling can result in longer runtimes, but it is more efficient. ? Heating demand can usually increase as the outdoor temperature drops. As you transition from fall into winter, you will typically see your heating demand increase. Similarly, in the spring heating demand will typically decrease as the weather warms up. Your report includes the average outdoor temperature for each month, enabling you to compare your change in heating demand to the change in temperature.

Cooling demand will typically increase as the outdoor temperature increases. Cooling demand will usually be the highest in the peak of Summer and drop off as temperatures decrease.

Single Stage
Single stage systems have only one operating capacity, on at 100%. Therefore the thermostat simply adjusts demand by changing runtime.

Two Stage
Two stage systems have two operating stages. The thermostat will first attempt to maintain comfort by operating only the lower stage. When the system cannot maintain comfort with the lower stage, it will begin to operate the higher stage.

Variable Capacity
Variable capacity systems continuously adjust the heating or cooling capacity from its minimum to its maximum capacity. The thermostat will maintain comfort by continuously adjusting the capacity of the system.

Electric Heat and Fan Demand calculations always assumes 100% capacity when on.

To access your iComfort^® S30 performance report on demand:

1. Login to your iComfort^® S30 account using the web portal (https://www.lennoxicomfort.com/account/login). Make sure to already have an iComfort^® S30 user account and have added your thermostat. For instructions on how to do this, please refer to the related questions section below.

2. Select your home and/or system in the "my homes" screen.

3. Once you are in the home screen, make sure your system is online and not in Away/Smart Away (otherwise the menu button is not available). Tap on the menu button on the top right.

4. Click on Performance Report.

To enable/stop receiving a monthly email containing the performance report of your iComfort^® S30 system, you can follow these steps:

On the web portal:

1. Log in to the iComfort^® S30 web portal.

2. Click on your account / email address at the top.

3. In the "account info" dialog, turn on/off "monthly performance report".

On the iComfort^® S30 Thermostat, you can go to menu > settings > account, scroll to the bottom of the screen and you should see the monthly performance report option.

The performance report display on-demand performance data from your iComfort^® S30 system for the last 10 days. It is divided into 3 sections:

1. The all-in-one graph

2. The table below

3. The hide/show panel on the right

The graph displays the variables that are turned on in the hide/show panel. The table below the graph displays the details for the day/hour selected in the graph. In order to customize the data that you see, you can:

1. Select day or hour at the top

2. Choose which variables to display on the graph by turning them on/off on the hide/show panel

3. Move the knob to view a specific day / hour

The temperature and humidity values represent the average for the day / hour. When hour is selected, the system mode and fan mode are those at the beginning of the hour. If the hide/show panel is not displaying in your web browser view, you are instead getting the menu button on the top right. If you tap on it, the hide/show panel will display. This is because your window size is not wide enough.

What variables can I turn on/off in the hide/show panel?

The variables you can control depend on the equipment that you have installed and the current operation of your system. For example, only customers that have electric heat will see electric demand as a variable. Here is a list of all the possible variables for an iComfort^® S30 system:

If the system is having issues obtaining data for a variable, it is not displayed on the graph, and instead it shows in this panel with a warning icon.

Please refer to the related questions below for the meaning of "demand" and "runtime".

The monthly performance report contains a summary of how hard the system worked (runtime and demand) for the past month and compares it to the previous month. Please refer to the related questions below for the meaning of runtime and percent demand. The report also contains other helpful information such as how much time your system spent on away mode, your home's average indoor temp., the average outdoor temperature for your zip code, and when your next filter replacement is due.

Demand varies with the outdoor weather. As the weather becomes more extreme, you can expect your HVAC system demand to increase. Your use of your home can also cause demand to change. For example, having extra guests visiting could increase cooling or heating demand depending on your setting. Alternatively, going on vacation could reduce demand if you set your system to Away mode or if you are using Smart Away.

Alexa will control your iComfort^® a little differently when it’s in ‘Heat and Cool’ mode, which can automatically switch between heating and cooling as needed.

For instance, if you ask Alexa to set the temperature to 70°F (21.0°C), your thermostat will use this as a midpoint temperature between the heat and cool setpoints,setting the Heat temperature to 69°F (20.5°C) and Cool temperature to 72°F (22.0°C)”. (By default your thermostat’s temperature deadband range is 3°F )

Alexa will confirm your request, saying “Thermostat is in auto mode, aiming for 70°F (21.0°C)”.

Raising or lowering the temperature is not supported when using a Perfect Temp or Schedule mode. When attempting to change the temperature while in either mode, Google Assistant will respond "mode not supported".

Google Assistant supports heat / cool mode temperature adjustments, but it will do so only by maintaining the currently established temperature ranged. For example, if you set your heat set point to 60ºF and your cooling set point to 80ºF at the thermostat itself, then you have established a temperature range of 20 degrees. Any adjustment using Google Assistant, either through the app or by voice will maintain a 20 degree range differential as well.

• On the iComfort thermostat go home page/ menu/ ventilation. Selections are timed, on, off, and ventilate now.

ASHRAE 62.2 is a national standard that provides methods for achieving acceptable indoor air quality in typical residences. It was developed and is maintained by the American Society of Heating and Air-Conditioning Engineers (ASHRAE). One of the standard three main components is Whole House Ventilation which is exhausting stale indoor air and replacing it with fresh outdoor air.

When ventilation is running the ventilation icon will appear on the home screen.

The Lennox iComfort^® implementation of demand response, referred to as “Peak Monitoring”, is compliant with the State of California’s Title 24, and other utility providers supporting Open Automated Demand Response (ADR). Check with your local utility provider to see if they have a demand response program.

Demand response allows you to play a role in reducing or shifting your electricity usage during maximum or peak periods. These peak periods are represented in the time of energy use (peak load) or with dynamic pricing (peak price). Often these peak times and dynamic pricing rates are in the afternoon, early evening and summertime.

Signing up for a demand response program with your utility provider could provide the following benefits:

• Save money on your utility bill during maximum or peak timeframes.
• Save power during maximum or peak times of energy usage in your area.

• Sign up with your utility provider.
• Make sure you have a compatible Lennox thermostat (such as the iComfort^® S30, E30 or M30).
• Go to your iComfort^® thermostat and select Menu > Settings > Peak Monitoring. Then you will be prompted through the enrollment process on your thermostat.

The iComfort^® S30, E30 and M30 support Peak Monitoring.

You will receive a message on your thermostat when successfully enrolled in your utility provider’s program.

Yes, you can cancel a Peak Monitoring event at anytime, before or during the event.

You can un-enroll your thermostat from your provider’s demand response program by selecting Menu > Settings > Peak Monitoring > Peak Monitoring Settings > Factory Reset Peak Monitoring Settings.
