If... Then...
Space heating/cooling is ON and
the operation mode is "heating"
The unit will supply leaving water to the
heat emitters to heat up the room
according to normal logic.
Space heating/cooling is ON and
the operation mode is "cooling"
There is no room frost protection.
External room thermostat control ([C‑07]=1)
Under external room thermostat control, room frost protection is guaranteed by
the external room thermostat, provided that:
▪ [C.2] Space heating/cooling = On , and
▪ [9.5.1] Emergency = Automatic or auto SH normal/DHW off .
However, if [1.4.1] Antifrost is activated, limited frost protection by the unit is
possible.
In case of one leaving water temperature zone:
If... Then...
Space heating/cooling is OFF and
the outdoor ambient temperature
drops below 4°C
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.
Space heating/cooling is ON, the
external room thermostat is "Thermo
OFF" and the outdoor temperature
drops below 4°C
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.
Space heating/cooling is ON and
the external room thermostat is
"Thermo ON"
Room frost protection is guaranteed by
the normal logic.
In case of two leaving water temperature zones:
If... Then...
Space heating/cooling is OFF and
the outdoor ambient temperature
drops below 4°C
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.
Space heating/cooling is ON, the
external room thermostat is "Thermo
OFF", the operation mode is "heating"
and the outdoor temperature drops
below 4°C
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.
Space heating/cooling is ON and
the operation mode is "cooling"
There is no room frost protection.
Room thermostat control ([C‑07]=2)
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.
