As well as the request by the AUX 1 circuit, the solar panels circuit circulation pump
will be activated for the following special cycles:
- auxiliary circuit low temperature protection
- anti-grip cycle
The correct functioning of the circulation pump 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).
N.B.
The AUX1 auxiliary circuit can be managed only in systems with individual heating solar panels circuits. If this is not
the case, all other enablings and settings made will have no effect.
8.4.5 Control of the high and low temperature of the auxiliary circuit
AUX1 (MCPS module)
Whenever the temperature of the AUX1 auxiliary circuit water exceeds or drops below the minimum and maximum
temperature values accepted for the system of the hysteresis value, then the c-pro 3 hecto MCPS solar panels
regulator will start special management cycles for these emergencies:
- High temperature protection: the high temperature protection intervention will trigger a simple signal to the
maintenance staff.
- Low temperature protection: the low temperature protection will trigger the activation of the circulation pump
of the auxiliary circuit in order to ease heating of the circuit water. The pump will remain on until the
minimum temperature conditions are recovered.
8.4.6 Management and setting of the periodic antilegionella cycle for
the DHW tank (MCPS module)
In order to disinfect the DHW tank from the proliferation of legionella bacteria due to the deposit of DHW, the
c-pro 3 CLIMA sistema envisions the periodic management of anti-legionella cycles.
Depending on the type of system, it is possible to select daily, weekly or monthly antilegionella cycles.
An anti-legionella cycle consists in taking, the temperature of the DHW tank to a temperature such to destroy bacteria
(standard to 70°C, but which can be set from parameter) for a long enough period of time (standard at 60 minutes,
but can be set from parameter) by activation of the boiler and the DHW circulation pump.
These periodic cycles will help with respect to the Standards in force on the subject.
