9.6.1 Management of the solar panels circuits circulation
(MCPS module)
The controller for the MCPS solar panels can manage up to 2 thermal solar panel circuits, each with
relative circulation pump.
The circulation pump is activated on temperature request of the DHW tank, whenever the
conditions described in previous paragraph 9.5.4. are satisfied.
As well as the request by the DHW tank, the solar panels circuits circulation pumps
will be activated for the following special cycles:
- periodic activation cycle for uniformity of temperatures
- solar panels circuits low temperature protection
- anti-stagnation emergency
- anti-grip 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).

9.6.2 Control of the high and low temperature of the solar panel circuits (MCPS
module)
Whenever the temperature of one of the solar panels circuits exceeds or drops below the minimum
and maximum temperature values accepted for the system of the hysteresis value, then the c-pro
micro MCPS solar panels regulator will start special management cycles for these emergencies:
- High temperature protection: after a fixed delay of 60 seconds, the high temperature
protection intervention will start an anti-stagnation emergency cycle (described in the
following paragraph), in order to dispose of the overheated water and to take the
temperature of the water back within the system safety conditions.
- Low temperature protection: after a fixed delay of 60 seconds, the intervention of the low
temperature protection will cause the activation of the solar panels circuit circulation pump
in order to ease heating of the water in the circuit. The pump will remain on until the
minimum temperature conditions are recovered.
