Testing second stage or auxiliary
heat after installation
Conventional heating
Before Nest has activated Time-to-Temperature, second stage heat will turn on
when the setpoint is 4°F or greater than the room’s ambient temperature.
Heat Pumps
Auxiliary heat will turn on when the setpoint is 4°F and the outdoor temperature
is below 50°F, the default auxiliary heat lockout temperature. Auxiliary lockout
can be turned off in the Heat Pump section of Advanced Settings in order to test
auxiliary heat.
To test second stage or auxiliary heat at installation, just raise the temperature
4°F in heating mode with the auxiliary lockout turned off. Once Time to
Temperature is activated, Nest will use this feature to manage second stage and
auxiliary heat.
