[C‑07]=0: leaving water temperature control
Under leaving water temperature control, room frost protection is NOT
guaranteed. However, if [2‑06] is set to "1", limited frost protection by the unit is
possible:
▪
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, then the unit will supply
leaving water to the heat emitters to heat up the room according to normal logic.
Shut-off valve
The following is only applicable in case of 2 leaving water temperature zones. In
case of 1 leaving water temperature zone, connect the shut-off valve to the
heating/cooling output.
The shut-off valve, which is in the main leaving water temperature zone, output is
configurable.
INFORMATION
During defrost operation, the shut-off valve is ALWAYS opened.
Thermo On/OFF
: the valve closes, depending on [F-0B] when there is no heating
demand from the main zone. Enable this setting to:
▪
avoid leaving water supply to the heat emitters in the main LWT zone (through
the mixing valve station) when there is request from the additional LWT zone.
▪
activate the On/OFF pump of the mixing valve station ONLY when there is
demand. See
29].

thermostat request setting (NOT in case of leaving water temperature setting).
Cooling
: The shut-off valve closes, depending on [F-0C] when the unit is running
in cooling operation mode. Enable this setting to avoid cold leaving water through
