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 o the compressor.
