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.
