Freeze Protection
The Freeze protection feature will not allow the
room temperature to drop below predefined cut-in
temperature. Depending on which configuration
the system is operating under (W/WO Heat pump)
this feature will force the system to operate in
heat mode and activate the fan.
This feature will take effect when the thermostat is
either ON or OFF. When the room temperature
rises above the predefined cut-out temperature,
the thermostat will return to its previous state.
When freeze protection is activated, the display
alternates between “AL” and room temperature.
