8.3.4 Management of digital on/off dehumidifier
The zone controller c-pro 3 hecto MCZN has two digital inputs (one for each zone) on/off dehumidifiers.
If the digital input is at logic level "disabled", the corresponding additional dehumidifier will be considered in the OFF
state and all of its settings are disabled.
In order to make such control active, the inputs must be activated through the appropriate parameters maintainer.
8.4 Regulation of the DHW tank temperature for the DHW
water (MCPS module)
8.4.1 Regulation principle
Whenever the c-pro 3 hecto 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 3 CLIMA sistema, 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The delivery hot water for any heating requests of the Zones is withdrawn directly from the DHW tank.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 3 CLIMA
sistema, 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.
8.4.2 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).
