Questions and answers
How to block aux heat from comming on with T9
To block auxiliary (aux) heat from coming on with the Honeywell T9 thermostat, set an aux heat lockout temperature. The T9 uses Accuweather data to determine the outdoor temperature. You can configure the lockout so that aux heat does not activate above a certain outdoor temperature, such as 15°F. This helps avoid using the heat strips unnecessarily.
To adjust this setting:
1. Open the thermostat menu.
2. Go to settings related to heat or equipment.
3. Find the aux heat lockout option.
4. Set the lockout temperature (e.g., 15°F).
This prevents aux heat from turning on unless the outdoor temperature drops below the set point.

Thermostat says 77 when set on 72
The Honeywell T9 thermostat may display 77 degrees when it is set to 72 degrees because rooms that are not selected or do not detect motion do not contribute to the average temperature. If only warmer rooms are selected or have detected motion, the thermostat calculates the average based on those, resulting in a higher displayed temperature.
This answer is automatically generated
1. Can you adjust the temperature differential in the cooling mode? Most are set at 1 degree can it be changed to 2 or 3 degrees? 2. Can you adjust the dead band or is it fixed? 3. Can you set the fan for a timed residual cooling after the compressor shuts off?
