Leaving water temperature control ([C‑07]=0)
Under leaving water temperature control, room frost protection is
NOT guaranteed. However, if room antifrost [1.4] is activated, limited
frost protection by the unit is possible:
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 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.
External room thermostat control ([C‑07]=1)
Under external room thermostat control, room frost protection is
guaranteed by the external room thermostat, provided that Space
heating/cooling [C.2] is turned ON and the emergency setting [9.5] is
set to automatic.
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
