9.6 Management and configuration of the heating solar panel
circuits (MCPS module)
Whenever the c-pro micro 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 two measurement inputs set-up to read the temperatures of the two circuits are the
4-20mA type. Therefore it is necessary to be equipped with a temperature transducer with 4-20mA
output or a converter able to convert the value read by the temperature probe into a
4-20mA signal.
For this purpose, EVCO suggests the use of the EVCONV01 accessory, i.e. a Pt100 / 4-20mA
converter able to convert the signal coming from the Pt100 3 probe wires at input into a 4-20mA
signal compatible with the c-pro micro MCPS measurement inputs.
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.
