5.5 Other regulations
5.5.1 Management of the auxiliary utilities (thermostat, hygrostat)
The MCSA module can manage (after configuration) an auxiliary thermostat and hygrostat.
5.5.1.1 Auxiliary thermostat
If a digital input is configured as “Auxiliary thermostat”, the activation of the digital input due to the activation of one
or more thermostats connected in parallel to the input in question causes the activation of the utilities connected to
the MCSA module (pump, mix valve, heat pump/boiler/chiller), similarly to the heat regulation request by one of the
two zones.
In this case, as well as activating the MCSA utilities, the thermostat contact must also activate the head of its
reference zone (not managed by MCSA).
5.5.1.2 Auxiliary hygrostat
If a digital input is configured as “Auxiliary hygrostat” and a relay output is configured as “Auxiliary dehumidifier” the
activation of the input causes the activation of the output and the other utilities used for the dehumidifying function
(pump, mix valve, chiller) if requested by the configuration (PD01=1 – Water use for enabled dehumidification)
5.5.2 Management and setting the anti-grip periodic cycle
The function has the purpose of preventing blocking of the pump and the valve present in the MCSA system during
system standstill periods due to any deposits present in the system or due to the formation of crystalline aggregates
(lime-scale or other) on the pump and valve mechanical seals.
The function automatically activates the pump and valve in sequence if they are at a standstill for at least one week.
The day and time of weekly activation can be set by the user via the appropriate Maintenance technician level
parameters.
The sequence scans the various system utilities every minute (pump and valve): the cycle leads to the 30 second
activation of the element taken into consideration.
