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.
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.
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.
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.
Auxiliary heat engages in heating systems, particularly heat pumps, when the outdoor temperature drops too low for the primary heat pump to operate efficiently. It helps maintain a comfortable indoor temperature by providing additional warmth when the heat pump's output is insufficient. Additionally, auxiliary heat may activate during periods of high demand or if the system is recovering from a significant temperature drop. This ensures consistent heating and comfort in colder conditions.
The auxiliary heat should run for a sufficient amount of time to reach and maintain the desired temperature in the space efficiently. This time can vary depending on factors such as the size of the space, insulation, outside temperature, and the efficiency of the heating system. It is recommended to consult with a heating professional to determine the optimal running time for your specific situation.
The "Auxiliary Heat" indicator on your Honeywell thermostat means that your heating system is using a backup heating source, typically electric resistance heaters, to help warm your home. This usually occurs when the primary heat pump is struggling to maintain the desired temperature, often in colder weather. It can also activate during defrost cycles when the heat pump is temporarily unable to provide adequate heating. If this light stays on for extended periods, it may indicate a problem with your heat pump.
Usually a backup heating unit. For instance in a heat pump when the temperature drops below the temperature where the heat pump cannot extract heat from the existing air electric heating elements kick in.
NO, But it is expensive.
The auxiliary heat may be running for a long time because the main heat pump is struggling to keep up with the desired temperature, especially in very cold weather. This can happen when the heat pump is not efficient enough to meet the heating demands of the home, so the auxiliary heat kicks in to provide additional warmth.
They both have to do with the transfer of heat. Heating an object is transferring heat into the system. Freezing an object is transferring heat out of the system.
