▪ When the leaving water temperature home page is ON and the operation mode
is "heating", then the unit will supply leaving water to the heat emitters to heat
up the room according to normal logic.
▪ When the leaving water temperature home page is ON and the operation mode
is "cooling", then there is no protection.
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.

thermostat request setting (NOT in case of leaving water temperature setting).
Cooling: ONLY applicable for EHYHBX. 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 the heat emitter and the forming of condensation
(e.g. under floor heating loops or radiators).
