Heat And Cool (Auto-Changeover); Additional Help; Google Home And Assistant; Perfect Temp And Schedule Mode Functions - Lennox S40 User Manual

NOTE: Even though the thermostat supports half degree settings in Celsius,
Amazon Alexa only supports whole degrees. The first temperature
adjustment that gets made will set the temperature to a whole
degree, if it was not already.

Heat and Cool (Auto-Changeover)

Amazon Alexa controls the thermostat a bit differently when in Heat / Cool
mode. In Heat / Cool mode, the system can automatically switch between
heating and cooling as needed.
For instance, if Amazon Alexa is commanded to set the hallway temperature
to 70 degrees, the thermostat will use 70 degrees as a midpoint temperature,
setting the Heat set point to 69 and Cool set point to 72. Amazon Alexa
will confirm the request by saying, "Hallway is in Auto mode, aiming for 70
degrees."
Amazon Alexa can change the thermostat mode (heat only, cool only, etc.)
via voice commands. It is recommended to rename the system to a call name
other than "System" or "system" during setup (such as "My System").
The following are examples of voice commands to a system named "My
System":
» Heat - "Alexa, set My System to HEAT."
» Cool - "Alexa, set My System to COOL."
» Auto - "Alexa, set My System to AUTO."
» ECO - "Alexa, set My System to ECO."
» OFF - "Alexa, set My System to OFF."
The following voice commands must be used for systems that remain as
"System" or "system":
» Heat - "Alexa, set Thermostat to HEAT."
» Cool - "Alexa, set Thermostat to COOL."
» Auto - "Alexa, set Thermostat to AUTO."
» ECO - "Alexa, set Thermostat to ECO."
» OFF - "Alexa, set Thermostat to OFF."
• If the thermostat is in Away or Smart Away mode, any Amazon Alexa
commands to change thermostat temperature will not be successful.
• Currently, users can pair only one home that is listed in their Lennox User
Account with Amazon Alexa. In the situation where there are multiple homes
associated with the Lennox thermostat account, users will not have a choice
to choose the home for Amazon Alexa. Users can view the homes on the
account by visiting: Amazon's on-line help at https://alexa.amazon.com.

Google Home and Assistant

Download the Google Home app from Google Play or the App Store™ on a
compatible mobile device and then follow the on-screen steps to finish setup.
Once the homeowner has added the thermostat to their Google Home app,
the homeowner should install and enable the Google Assistant app (Android
and IOS) to enable voice control.
NOTE: Google Assistant app may be already installed on Android devices.

Perfect Temp and Schedule Mode Functions

Raising or lowering the temperature is not supported when using a schedule
or Perfect Temp feature. When attempting to change the temperature when
in either reference mode, Google Assistant will respond with mode not
supported.

Heat / Cool Mode (Auto-Changeover)

Although Google Assistant supports heat / cool mode temperature
adjustments, it will do so only by maintaining the currently established
temperature ranged. For example, if the heat set point is 60ºF and the cooling
set point is 80ºF at the thermostat itself, then a temperature range of 20
degrees has been established. Any adjustment using Google Assistant, either
through the app or by voice will maintain a 20 degree range differential as
well. Let's say the homeowner changes their heat set point to 65ºF. Now the
thermostat will indicate the heating is at 65ºF and cooling is set at 85ºF.
Adjusting the cooling set point will result in the range being maintained as
well. In the Google Home app, the thermostat image will only display the
approximate center temperature between the current heating and cooling set
points. In this example it would display 75ºF.
