1.24 CIRCULATION PUMP.
The boilers are supplied with a variable speed
circulator pump.
When the boiler is in the heating phase, pump
speed is defined by the setting of the parameters
“P27” and “P28” and varies so as not to exceed
the ∆T of 18 °C.
In domestic hot water mode the circulator pump
always runs at maximum speed.
Pump release.
If, after a prolonged period of
inactivity, the circulation pump is blocked,
unscrew the front cap and turn the motor shaft
using a screwdriver. Take great care during this
operation to avoid damage to the motor.
