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.
4
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).
4
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
.

See chapter: "Professional settings", page 84.
3.3.3.
Water flow rate
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.
