Thermostat Summary
Indicates the thermostat’s software and version.
Heat Pump Lockout (outdoor sensor required)
Available only for heat pump systems with indoor electric heat. This feature disables the heat pump and turns on auxiliary heat below the selected outdoor temperature. The temperature range is from 5° to 50°F.
Dual Fuel Setpoint (outdoor sensor required)
If the heating system is a heat pump with auxiliary gas heat and the outdoor sensor is installed, the thermostat can monitor outside temperature to determine when to begin using the gas heat system and stop the compressor. This temperature is the Dual Fuel temperature setpoint. The Dual Fuel feature eliminates the need for a fossil fuel kit.
The display will indicate 5° (default). The temperature can be adjusted to a value between 5° to 50°. The temperature will appear as °F unless °C is selected for temperature display.
As long as the outside temperature is above the Dual Fuel Setpoint, the compressor will operate. When the temperature drops below the setting the thermostat will start the gas heat and shut off the compressor.
