9.7 Other regulations
9.7.1 Management and setting of the periodic anti-grip cycle
(MCCT, MCPS modules)
The function has the purpose of preventing the blocking of the pumps and valves present in the c-
pro CLIMA system during system standstill due to any deposits present in the system or due to the
formation of crystalline aggregates (lime scale or other) on the mechanical seals of the pumps and
valves.
The function automatically activates all pumps and valves in sequence once a week, which have
been at a standstill for at least a week.
The day and time of weekly activation can be set by the user via the relevant Maintenance
technician parameters.
The sequence scans the various utilities in the system every minute (pumps and valves): the cycle
leads to the activation of the element considered for 30 seconds.
The enabling and setting of the periodic anti-grip cycle is set separately on the thermal power plant
c-pro mega MCCT controller and on the c-pro micro MCPS module for solar panels, respectively
for the following utilities:
MCCT regulator anti-grip : delivery 1 circulation pump if enabled from parameter
delivery 1 mixing valve if enabled from parameter
delivery 2 circulation pump if enabled from parameter
delivery 2 mixing valve if enabled from parameter
MCPS regulator anti-grip : DHW circuit circulation pump always enabled
AUX1 circuit circulation pump always enabled
solar panels 1 circuit circulation pump always enabled
solar panels 2 circuit circulation pump always enabled

9.7.2 Management of the circulation pumps protection digital input
(MCCT, MCPS modules)
Every circulation pump present in the c-pro CLIMA system has a protection digital input.
Every protection digital input linked to a circulation pump can be associated to one of the following
functionalities, depending on the value selected via the relevant parameters.
- THERMAL SWITCH: every activation of the digital input will cause the immediate
deactivation of the relative circulation pump.
Once the digital input is deactivated, the circulation pump will start to work according to its
own regulation (automatic rearm).
