Questions and answers
How do I get the main screen to show both the cool and heat on the front screen.
The Lennox X4146 thermostat has an "AUTO" mode under the SYSTEM settings, which allows both heating and cooling setpoints to be displayed on the main screen. To enable this:
1. Press the "SYSTEM" button.
2. Select "AUTO" mode.
3. The thermostat will now show both heating and cooling temperature settings on the main display.
If the option is not available, check the installer settings to ensure "AUTO" mode is enabled.
