protect both
the room and the equipment when the room temperature
falls below the set value.
The parameter can be set in the range OFF, 0,5°C .. 25°C.
The device leaves the factory with the Antifreeze function set on
3°C.
IMPORTANT: the function is active only when the device has
been set in the heating mode.

OFS1
’ INTERNAL SENSOR OFFSET SETTING
With this parameter it is possible to correct the temperature reading
of the internal sensor by ±5°C in order to correct any systematic
reading errors due to the positioning of the programmable thermostat
in areas unsuitable for measuring the room temperature.
The device leaves the factory with the Offset set at 0.0°C.
‘
OFS2
’ REMOTE SENSOR OFFSET SETTING
With this parameter it is possible to correct the temperature reading
of the remote sensor by ±5°C in order to correct any systematic
reading errors due to the positioning of the remote sensor in areas
unsuitable for measuring the room temperature.
The device leaves the factory with the Offset set at 0.0°C.
