System suggestion of the unit with accessory rc100/ds and dhw production management
IMPORTANT!
The type of system described below could lead to lime scale forming in the
water/refrigerant heat exchanger. We therefore recommend taking suitable steps
to limit this phenomenon. When operating as a heat pump, it is advisable to drain
the recovery circuit.
Closed circuit system (for heating, for example)
ST6 (RC100)
VSM
ST5 (RC100)
ST7 (DS)
C
Open circuit system (for hot water, for example)

Pay particular attention to the operating pressure of the system that
must not exceed the plate values on the individual components and
must be such to avoid the boiling of the water contained in the recovery
unit.
Also ensure, through mixing units, the continuous circulation of water
through the heat recovery unit or desuperheater.
