During room thermostat control, room frost protection [2‑06] is guaranteed when
activated. If so, and the room temperature drops below the room antifrost
temperature [2‑05], the unit will supply leaving water to the heat emitters to heat
up the room again.

INFORMATION
When the user interface used as room thermostat is disconnected (because of
incorrect wiring or damage of the cable), then room frost protection is NOT
guaranteed.
NOTICE
If Emergency is set to 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.
Setpoint range
Only applicable in room thermostat control.
To save energy by preventing overheating or undercooling the room, you can limit
the range of the room temperature for heating and/or cooling.
NOTICE
When adjusting the room temperature ranges, all desired room temperatures are
also adjusted to guarantee they are between the limits.

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 user interface used as room thermostat
or by the external room sensor. The setting can be used to compensate for
situations where the user interface used as room thermostat or the external room
sensor cannot be installed at the ideal location.
