Enabling Auxiliary Heat for Your Heat Pump
To put a heat pump in auxiliary mode, follow these steps.
The exact process can vary slightly depending on your thermostat model and heat pump system, but the general steps are outlined below:
1. Understand Auxiliary Mode
Auxiliary mode (or AUX heat) engages backup heating, often electric resistance heat or a gas furnace, used when the heat pump cannot maintain the desired temperature on its own (e.g., during very cold weather).
2. Access the Thermostat
Identify the Thermostat Type:a. Manual thermostat
b. Programmable or smart thermostat (e.g., Nest, Honeywell, etc.)
Switch to Heat Mode:
a. Ensure your thermostat is set to "Heat."
3. Enable Auxiliary Heat
Manual Thermostat:1. Locate a switch labeled "Heat," "Emergency Heat," or "Aux Heat."
2. Flip the switch to "Emergency Heat" or "Aux Heat" to enable the backup heating system.
Programmable or Smart Thermostat:
1. Access the thermostat's settings or menu.
2. Look for options such as "Emergency Heat," "Auxiliary Heat," or "Backup Heat."
3. Select the option to activate AUX heat.
4. Monitor the System
Check the display on the thermostat. It should indicate that auxiliary or emergency heat is active (e.g., "AUX Heat" or "Emergency Heat" will light up). The system will use backup heat to reach or maintain the desired indoor temperature.
5. Return to Normal Heat Pump Operation
Check the display on the thermostat. It should indicate that auxiliary or emergency heat is active (e.g., "AUX Heat" or "Emergency Heat" will light up).The system will use backup heat to reach or maintain the desired indoor temperature.
Tips
- Check the display on the thermostat. It should indicate that auxiliary or emergency heat is active (e.g., "AUX Heat" or "Emergency Heat" will light up).
- The system will use backup heat to reach or maintain the desired indoor temperature. Once the extreme conditions pass, switch the thermostat back to normal heat pump operation by deactivating AUX or Emergency Heat mode.
- Use AUX heat sparingly, as it is typically less energy-efficient and can increase energy bills. Consult your system's manual for specific instructions related to your model.
- If your thermostat doesn't have an obvious AUX mode, check the manufacturer's website or user manual for guidance.
- If your system does not respond as expected, there may be an issue with the heat pump or thermostat wiring that requires professional inspection.
