What temp should AUX heat come on?

What temp should AUX heat come on?

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.

Does a heat pump automatically switch emergency heat?

Because the backup heat source runs automatically, there’s no need to switch to emergency heat under normal operation.

How expensive is auxiliary heat?

When operating in the auxiliary/emergency heating mode, that cost goes up to around $1.30 per hour. If your heat pump is operating in auxiliary/emergency mode without due cause (outdoor temperatures are above freezing or no drastic adjustment to your thermostat), it is possible that your system is malfunctioning.

Why does my thermostat say auxiliary heat?

Turning your thermostat to “heat” came with an unexpected “AUX” function appearing. The “AUX Heat” mode is usually an indicator that it’s freezing outside, and your is heat pump is using a secondary backup heat source – your auxiliary heat—to keep your home at your set temperature.

Can you turn off auxiliary heat?

Though you cannot manually shut off your auxiliary heat, you can do things to prevent it from kicking in—to a point, anyway. To do this, you either have to raise your home’s temperature or lower the burden of your heating system.

How do I stop using auxiliary heat?

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.

How do I stop nest from using auxiliary heat?

Go to SETTINGS > NEST SENSE (which is the 4th setting from the left). Select “Heat Pump Balance”. Choose “OFF”. You must do this first, because the other settings won’t be settable unless you turn off this feature (temporarily, just so you can access the options).

Why does my nest say Alt heat?

Nest is calling for alt heat (furnace) instead of heat (heat pump) because nest is retarded.

What does AUX heat mean on Nest?

auxiliary heat

How do I force auxiliary heat to my nest?

I can manually force it to kick in by turning the heat up a few degrees, then back down to the desired temp once it kicks in. As long as there is a spread of 4+ degrees it will turn on.

Does using emergency heat cost more?

Using Emergency Heat May Cause Higher Heating Bills: Emergency heat is more expensive than its traditional counterpart, so you will probably see a spike in your utility bills if you need to use it. You should use emergency heat for the shortest period of time possible.

Should heat pump and AUX heat run simultaneously?

The system is designed so that both can operate simultaneously. As long as the HP is producing some heat, it’s more efficient to use the HP for whatever Btu’s you can garner and allow the aux heat to be just that, auxiliary rather than primary. Electricity is inherently less energy efficient than running the HP.
