An anti-condensate pump operates during periods of
no heat request to avoid damage until the boiler returns
to a stable operating temperature. While the system is
operating, this pump must guarantee a flow rate between
20 and 30% of maximum flow, must ensure a water return
temperature no lower than the minimum permissible (see
technical data) and must also delay shutting down for at
least 3 minutes at the beginning of extended periods of
boiler shutdown (overnight or weekend shutdown etc.).
b
A sensor socket must be positioned at a distan-
ce of 3 to 5 times the diameter of the water return
pipe, upstream from the water fitting, to measure
effective water return temperature and control the
anti-condensate pump or the temperature controller
stabilisation function.
b
Any temperature controllers installed remotely from
the control panel must be compatible with the
system’s electrical connections and functioning
logic.
