9.5 Regulation of the DHW tank temperature for the DHW
water
(MCPS module)
9.5.1 Regulation principle
Whenever the c-pro micro MCPS module is present and enabled in the system, the system will
automatically consider the presence of a DHW storage tank in the system for the DHW.
With the presence of the DHW tank, the temperature regulation principle of the entire system will
change significantly in the following way:
- WINTER REGULATION Via its utilities proposed for heating, the c-pro CLIMA system,
always keeps the DHW tank at the pre-fixed temperature.
The delivery hot water for any heating requests of the Zones is withdrawn directly from the
DHW tank.
- SUMMER REGULATION: Via its utilities proposed for heating EXCEPT the heat pump,
the c-pro CLIMA system, always keeps the DHW tank at the pre-fixed temperature.
The cool delivery water for any cooling requests from the Zones will be supplied by the
chiller unit, obviously without the use of the DHW tank.
9.5.2 Management of the DHW circuit circulation pump (MCPS module)
The MCPS solar panels controller can manage a DHW tank with relative circulation pump.
The circulation pump is activated on temperature request of the DHW tank, whenever the heat
pump or boiler utilities are used to heat the DHW. When the use of the solar panel circuit/s for
heating is sufficient, the DHW circulation pump will not be used.
The activation of the DHW circulation pump will follow the delay times on switch-on established
via the relevant parameter.
As well as the request by the DHW tank, the DHW circulation pump can be activated during a
special anti-grip or antilegionella cycle.
The correct functioning of the circulation pumps is controlled via a digital input that can be
configured as pump protection input (thermal switch) or delivery flow switch (consult the relative
explanatory paragraph).
