functioning of the heating
system
Check correct operation of the
heating system and adjust the
operating parameters of the boiler
and/or of the heating system control
valves if needed.
These interventions
must be carried out by an authorised
technician. When the boiler has

and the cause of the boiler
overheating has been remedied,
unscrew the protection cap from the
emergency overheating thermostat
and press the stem until the
thermostat is reset, then screw the
cap back on. Turn the “POWER” main
switch on and off and then restart
