Does a heat pump automatically switch emergency heat?
Your heat pump is an intelligent machine. It has settings that tell it when its efforts to heat your home aren’t working and automatically switches to second-stage heating. When the target temperature is reached, the backup heater turns off and first-stage heating resumes.

When Should I Switch My Heat Pump Thermostat to Emergency Heat? [FAQ] Short answer: You should only set your heat pump’s thermostat to “emergency heat” when your heat pump stops heating altogether. And in that case, you should also call a professional for help.
At what temperature does a heat pump go to auxiliary heat?

-4°F is the lower limit of our air source heat pump effective temperature range. In temperatures lower than that the heat pump shuts down and electric backup heat takes over. The backup heat protects the compressor and preserves the longevity of the machine.
What happens when you switch your thermostat to emergency heat?
Switching your thermostat to emergency heat is you telling your heat pump this: “Hey, stop trying to pull in air from outside. Just use your backup heat.” Your heat pump gladly complies.
