FAQs

Find answers to common questions about your thermostat from setup and Wi-Fi connection to troubleshooting and energy-saving tips.

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 range. 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 Lennox Home App or by voice will maintain a 20 degree range differential as well.
