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% maximum flow to ensure a water return
temperature no lower than 55 °C. Pump shutdown must
also be delayed for at least 3 minutes at the beginning of
extended periods of boiler shutdown (overnight or week-
end 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.
