Steps
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.
Switching modes
To switch to and from heating and cooling modes, follow these steps:
• Press the ring to bring up the menu.
• Select the Red and Blue dots.
• Turn the ring to select HEAT, COOL, HEAT • COOL, or OFF.
• Press the ring again to select.
Both auxiliary and compressor lockout temperatures can be changed in the Heat
Pump section of the Advanced Settings menu. By default, Nest will lock out the
auxiliary heater when the outdoor temperature is above 50°F but will not lock out
the compressor at any temperature.
The lockout temperatures are only enforced when Nest is connected to Wi-Fi so
it can track outdoor temperatures.
To access the Heat Pump section of Advanced settings:
• Press the ring to bring up the menu.
• Turn the ring and select SETTINGS.
• Turn the ring and select ADVANCED.
• Turn the ring and select HEAT PUMP.
Follow these steps:
1. Press the ring to bring up the menu.
2. Turn the ring and select SETTINGS.
3. Turn the ring and select ADVANCED.
4. Turn the ring and select HEAT PUMP.
