then room frost protection is NOT guaranteed.
NOTICE
If
Emergency

Manual
([9.5.1]=0), and the unit is triggered to start
emergency operation, the unit will stop and needs to be recovered manually via the
user interface. To recover operation manually, go to the
Malfunctioning
main
menu screen, and confirm emergency operation before starting.
Room frost protection is active even if the user does not confirm emergency
operation.
Room sensor offset
Only applicable in room thermostat control.
To calibrate the (external) room temperature sensor, give an offset to the value of
the room thermistor as measured by the Human Comfort Interface (BRC1HHDA
used as room thermostat) or by the external room sensor. The setting can be used
to compensate for situations where the Human Comfort Interface or the external
room sensor cannot be installed at the ideal location.
