At what temperature should you use auxiliary heat?
At what temperature should you use auxiliary heat?
Auxiliary heating turns on automatically to help heat your home more quickly if the temperature drops suddenly. The emergency heat setting has to be manually switched on and should only be used in temperatures below 30 degrees.
What is auxiliary heat lockout?
If it gets colder outside than the set lockout temperature, your heat pump will use AUX heat. For example, if your AUX lockout temp is 40ºF or 4.4ºC, then AUX heat will come on when the outdoor temperature drops below 40ºF or 4.4ºC.
At what temperature does a heat pump go to auxiliary heat?
around 35-40 degrees
Auixiliary Heat will turn on automatically when heat can no longer efficiently transfer heat from the outside air to heat pump. This is when the outside is around 35-40 degrees and the indoor temperature is around three degrees cooler than the thermostat setting.
How often should auxiliary heat come on?
When should my auxiliary heat come on? When outside temperatures drop below 40 degrees. While undergoing the defrost cycle. When there is a 3 degree difference or more in the current temperature in your home and the thermostat setting.
Will AUX heat turn off?
When the temperature inside your home drops a certain amount below the goal temperature (usually 1.5-2 degrees), your thermostat energizes auxiliary heat. The aux heat indicator on your thermostat lets you know when this is happening. Aux heat will turn off once your home reaches the thermostat set point.
Is it bad if auxiliary heat comes on?
Is AUX heat bad? The short answer is no. In fact, aux heat is a critical mechanism that keeps your heat pump properly running when the outdoor temperature drops. Since this type of unit doesn’t work the same as a furnace, it can get cold.
Is AUX heat more expensive?
Auxiliary heat can handle more extreme temperatures since it uses electric heat strips. What this means, unfortunately, is that it’s more expensive than the conventional heat provided by a heat pump. While a gas furnace is not as efficient as a heat pump, it is more efficient than a heat pump using auxiliary heat.
What is auxiliary heat?
Auxiliary heat on your thermostat refers to your backup heating system within your heat pump, otherwise known as electric resistance heating. This is because when the temperature inside your home drops below the goal temperature you’ve set the thermostat to, your thermostat energizes auxiliary heat.
How do I stop my auxiliary heat from coming on?
Shut the door and close the vents so that the rest of the warm air can be redirected to the rest of your home. If the temperatures are extremely frigid outside, even this may be too much for your unit. You may need to make some additional changes to your home to keep the auxiliary heat from coming on.
What causes AUX heat to come on?
Aux heat should only kick on when the heat pump can’t produce enough heat to warm your home on its own. This is typically caused by one of three factors: when it’s below 35° outside, you’re trying to heat your home by 3° or more, or your heat pump is in defrost mode.
Should heat pump and AUX heat run simultaneously?
Allow Heat Pump/Auxiliary Heat to Run Simultaneously: If you select Yes and there is a source of auxiliary heat, both auxiliary heat and heat pump will turn on. This option should also be used for installation where the heat pump evaporator coil is downstream from the source of auxiliary heat.
Why is my auxiliary heat always on?
More often than not, the aux heat is coming on because the temperature in the home is set too high. You are asking your HVAC system to work too hard to maintain a comfortable temperature. Setting the thermostat for somewhere between 62-68 degrees is all you should need to do to get the problem under control.
Why is my heat pump stuck on auxiliary heat mode?

What is auxiliary heat on a heat pump?
Auxiliary heat is when the secondary heat source turns on automatically. This means, when the temperatures start to drop and your heat pump cannot produce enough hot air to warm your home the aux heat will turn on. Emergency heat is when you turn on a secondary heat source manually. Does Auxiliary Heat Cost More to Run?
What is the difference between aux heat and emergency heat?
Auxiliary heat is when the secondary heat source turns on automatically. This means, when the temperatures start to drop and your heat pump cannot produce enough hot air to warm your home the aux heat will turn on. Emergency heat is when you turn on a secondary heat source manually.
