How does the Honeywell thermostat system utilize auxiliary heat to maintain optimal temperature control in a home?

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.

Why does it say Auxiliary Heat on my Honeywell thermostat?

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.


Why is my ecobee auxiliary heat running for an extended period of time?
