8.5 Management and configuration of the heating solar panel
circuits (MCPS module)
8.5.1 With DHW setpoint
Whenever the c-pro 3 hecto MCPS module for solar panels is present and enabled in the system, one or two heating
solar panel circuits management can be enabled, with the function of heating the DHW in the DHW tank.
The heating solar panels circuits will be added to the other utilities set-up for heating the DHW tank, with PRIMARY
importance with respect to the other utilities, with the following functioning principle:
- with heating request by the DHW tank, when the temperature of the solar panels circuit is over a value set by
the (Offset ON) (ON Offset) parameter at the temperature of the DHW tank, then the solar panels circuit will
start its own water circulation pump, in a way to contribute with the heating of the DHW tank.
Whenever the contribution of the solar panels circuits is sufficient to reach the DHW set-point, at this point the
solar panels circuit circulation pump will be switched off.
Whenever the difference between solar panels and DHW tank temperature becomes lower than a value set by
( OFF Offset) parameter, the solar panels circulation pump will be switched off and the other utilities set-up
for heating will be activated (heat pump or boiler, with the rules and times described in the previous points),
in order to reach the work set-point set for the DHW tank.
The presence of the second circuit of solar hating panels automatically disables the presence of the AUX1 auxiliary
circuit and of the management of the anti-stagnation emergency in Tenda2 (Cover2) mode.
8.5.2 con tipo setpoint pannelli
If it is present and enabled in the plant the c-pro 3 hecto MCPS module for solar panels, is possible to enable the
management of one or two circuits of solar panels, with the fuction to heat the the domestic water of the DHW tank.
The heating panel circuit will be added to the other heating loads of the DHW tank, with integrative priority on other
loads, with the following functioning:
- with heating request from the DHW tank, when the temperature of the solar panels circuit is higher of a set
value (Offset ON) of the lower temperature od DHW tank, the solar panel circuit will start the water
circulation pump, to help to the DHW tank heating.
If the difference between the solar panel temperature and the DHW tank lower temperature is lower than the
value set by parameter (Offset ON), the solar panels water circulation pump will stop.
The presence of the second solar panel circuit will automatically disable the presence of the AUX1 auxiliary circuit and
the emergency anti-stagnation in Tenda2 mode.
