To activate auxiliary heat on the Honeywell VisionPRO 8000 at a specific temperature, follow these steps:

1. If you have an optional outdoor sensor, set option 350 to the desired outdoor temperature at which the system switches from heat pump to gas.
2. Ensure the thermostat settings are configured correctly:
- Option 170 = 7
- Option 200 = 1
- Option 210 = 1 (if using an external fossil fuel kit) or 0 (if using the outdoor sensor for backup heat control).
3. The thermostat will automatically turn on auxiliary heat when needed, indicated by "Aux Heat On" on the display.

This setup ensures that auxiliary heat activates based on the system’s programmed temperature thresholds.

The Honeywell 8000 auxiliary heat will come on at the outdoor temperature you set in the "Backup Heat Lockout" setting. To make auxiliary heat come on only when the outdoor temperature is 20°F or below, set the Backup Heat Lockout to 20°F and leave the Heat Pump Lockout off.

To set the auxiliary heat on the Honeywell VisionPRO 8000:

1. Touch the System button until Emergency Heat appears.
2. Ensure that the thermostat model supports auxiliary heat (TH8320 or TH8321).
3. Verify the following settings:
- Option 170 = 7
- Option 200 = 1
- Option 210 = 1 (if using an external fossil fuel kit) or 210 = 0 (if using an optional outdoor sensor for backup heat control).
4. If you have an optional outdoor sensor, set Option 350 to adjust the outdoor temperature at which the system switches from heat pump to gas.

When auxiliary heat is activated, the thermostat will display "Aux Heat On."

The Honeywell VisionPRO 8000 allows the auxiliary heat to be locked out at temperatures between 40 to 60 degrees Fahrenheit when using an outdoor sensor. However, with certain setups, the auxiliary heat may not turn on until the temperature drops below 15 degrees Fahrenheit.
