  If your Lennox thermostat isn't activating the heating or cooling, it could be due to several reasons: 1. The thermostat's minimum-off time might be active. In this case, wait up to 5 minutes for the system to respond. 2. The system selection may not be set to heat or cool. Ensure that you have selected the proper system mode. 3. The system type selection could be incorrect. Verify that the correct system type is selected in installer setup number 0170.
