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 oper-
ating, 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 distance
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 sys-
tem’s electrical connections and functioning logic.
