4.3.2. Circulation pump
The boiler is fitted with a modulating pump which is regulated by the
control panel as a function 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.
4If 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).
4If 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.

The boiler’s modulating control system limits the maximum difference
in temperature between the heating flow and return and the maximum
speed at which the flow temperature increases. In this way, the boiler
does not require a minimum water flow rate.
