Auxilliary heat is on... Change the filter... Then reset the filter change reminder and if the filter is not dirty extend the filter chamge reminder for a longer interval.
NO, But it is expensive.
The auxiliary heat in your heating system comes on when the primary heat source, such as a heat pump, is unable to meet the desired temperature setting. This usually happens during very cold weather or when the primary heat source is not functioning efficiently. The auxiliary heat helps to supplement the primary heat source and maintain a comfortable temperature in your home.
To prevent auxiliary heat from turning on in your heating system, you can try lowering the thermostat setting, ensuring proper insulation in your home, sealing any drafts, and maintaining your heating system regularly.
To turn off the auxiliary heat in your heating system, locate the thermostat and look for an option to adjust the settings. You may need to switch the thermostat to a different mode or lower the temperature setting to prevent the auxiliary heat from turning on. If you are unsure, consult the user manual or contact a professional for assistance.
The thermostat says "auxiliary heat on" when the primary heating system is not able to keep up with the desired temperature, so an additional heat source is activated to help maintain the set temperature.
The auxiliary heat should run for a sufficient amount of time to effectively support the primary heating system and maintain a comfortable temperature in the space.
The Honeywell thermostat system uses auxiliary heat to help maintain the desired temperature in a home when the primary heat source, such as a heat pump, is not sufficient. The thermostat detects when the primary heat source is struggling to keep up with the demand for heat and automatically activates the auxiliary heat to provide additional warmth. This helps ensure that the home stays at a comfortable temperature even during extreme weather conditions.
The heat pump auxiliary heat may be always on if the temperature outside is very cold and the heat pump alone cannot efficiently heat the home. The auxiliary heat helps provide additional warmth when needed.
To prevent the auxiliary heat from activating on your Honeywell thermostat, you can adjust the temperature settings to a level that does not trigger the auxiliary heat. Additionally, you can check and adjust the settings on your thermostat to ensure that the auxiliary heat is not set to turn on automatically.
To prevent your auxiliary heat from turning on, you can try lowering your thermostat setting, ensuring your primary heat source is working efficiently, and properly insulating your home to retain heat.
To optimize the use of your Honeywell thermostat's auxiliary heat function for improved energy efficiency and comfort in your home, consider setting the temperature differential between the primary and auxiliary heat sources to a minimum of 2-3 degrees. This will help prevent unnecessary use of the auxiliary heat and reduce energy consumption. Additionally, ensure that your thermostat is programmed to activate the auxiliary heat only when necessary, such as during extreme cold weather conditions. Regularly maintaining your HVAC system and keeping your home well-insulated can also help improve energy efficiency and comfort.
During an emergency. i.e. when the heat pump is not working. If your heat pump can not keep your house warm, then the auxiliary heating coils (same thing as emergency heat) will come on automatically. If not, then there is a problem with your heating system.
