drop below predefined cut-in temperature. Depending on which
configuration the system is operating under (with or without 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.

1.11 Freeze protection
The thermostat continuously monitors the ambient CO2level using the
built in CO2sensor and compares the readings to the CO2set-point.
When the ambient CO2level rises above the set-point, the fresh air
damper will open to bring in fresh air.
Additionally, when the ambient CO2level exceed the high limit alarm,
an indication will appear on the display.
The values of the CO2set-point and high limit alarm, together with
other CO2parameters are set by technician.
Please refer to parameters P180-P185 in the technician setting section.
All CO2parameters and readings can be monitored through BMS and
optionally trigger other air handling devices to take action.
The CO2ambient reading can either be displayed constantly or hidden
by setting either “0” or “1” to technician parameter P180.
Important: Please allow 12 hours of operation from initial power up,
before reading a reliable CO2value.
