emergency operation, the user interface will ask confirmation before starting. Room
frost protection is active even if the user does NOT confirm emergency operation.

Under external room thermostat control, room frost protection is guaranteed by
the external room thermostat, provided that the leaving water temperature home
page is ON on the user interface, and the auto emergency setting ([A.6.C]) is set to

In case of… …then the following applies:
One leaving water temperature zone ▪ When the leaving water temperature
home page is OFF and the outdoor
ambient temperature drops below
4°C, then the unit will supply leaving
water to the heat emitters to heat up
the room again, and the leaving water
temperature setpoint will be lowered.
▪ When the leaving water temperature
home page is ON, the external room
thermostat is "Thermo OFF" and the
outdoor ambient temperature drops
below 4°C, then the unit will supply
leaving water to the heat emitters to
heat up the room again and the
leaving water temperature setpoint
will be lowered.
▪ When the leaving water temperature
home page is ON and the external
room thermostat is "Thermo ON",
then room frost protection is
guaranteed by the normal logic.
