SHUTDOWN DUE TO OVERHEATING
In the event that the safety limit is
exceeded for the temperature of the
water in the boilers exchanger, the
thermostat shuts off the
boiler and the red L.E.D.

To remedy this situation,
wait a few minutes to
allow the exchanger to
cool down, then press
and release the reset
button “J”.
If this situation occurs frequently,
contact an Authorised Service Centre.
SHUTDOWN DUE TO INSUFFICIENT
WATER CIRCULATION
If the boiler is off, one possible cause
for this state is an insufficient pressure
of water in the system.
Check the system pressure on the
pressure gauge “D” and if it is less
than 0.5 bar, consult your installer for
checking and refilling
the system.
If the boiler does not
start up again, contact
an Authorised Service
Centre.
If there are frequent drops in pressure
within the system, have a plumber
