Water flow
The boiler is fitted with a modulating pump which is regulated by the
control panel as a fuction of ΔT.
The graph shows the manometric height at various outputs. The
parameters
MIN.PUMP SPEED
and
MAX.PUMP SPEED
are used to
modify the pump settings. If flow noise can be heard in the system, it
is possible to reduce the maximum pump speed with the parameter
MAX.PUMP SPEED
(First of all, vent the heating system). If
circulation in the radiators is too low or the radiators do not fully heat
up, increase the minimum pump speed with the parameter
MIN.PUMP SPEED
.
