Domestic hot water
Option.
The unit with DHW option is equipped with a 3-way
valve on board mounted (3DHW)
Each unit with DHW option must have its own DHW
storage.
The pumping unit is managed directly by the unit
with DHW option via clean contact (PUMP-N)
The management of domestic hot water takes
priority over the system.
In DHW production mode the compressors start
only if the DHW storage temperature is above a
minimum threshold (T5) (→ table).
The temperature threshold varies based on the
outdoor temperature. To prevent it from falling
below the minimum temperature, it is advisable to
install a backup electric heater on the DHW storage
(KAH2).
Verify that S12-2 is ON.
