Potentiometers on the control panel
The thermostatic valve must be set to the same
temperature selected with the knob of the water
potentiometer (A=B).
If the thermostatic valve is set to a lower or higher
temperature as compared to the one of the boiler,
the exhaust water temperature may not correspond
to the desired one.
TURNING THE BOILER OFF (fig. 25)
When the selector is in OFF posi-
tion, the boiler is in standby, the
green LED flashes at intervals of
five seconds and all features are disabled,
except the pump anti-blocking feature.
Move the bipolar switch to "OFF" to
disconnect the unit from the power supply.
If the boiler is not going to be used for a
lengthy period it is advised to turn off the
electricity supply, close the gas cock, and if
low temperatures are foreseen, empty the
boiler and the hydraulic system to avoid
breakage in the tubes due to the freezing of
the water.

for which the boiler has been equipped,
approach the technical staff.
CLEANING AND
MAINTENANCE
Preventive maintenance and checking of
the efficient operation of the equipment
and safety devices must be carried out
exclusively by the authorized technical
staff. The boiler is supplied with an elec-
tric cable.
Should this require replacement, contact
exclusively with the authorized technical
staff.

– Restoring pressure in the
heating system (fig. 27/a)
Periodically check that the pressure in
the system is between 1 and 1.2 bar. If
the pressure is below 1 bar when the
system is cold, top up using the filling tap
until the pressure gauge indicator falls
within the blue range (2).
