– Make sure that the boiler is suf-
ficiently powerful for the appliance.
Smell of unburnt products
– Control the cleanness of the boiler
shell and the flue, the airtightness
of the boiler and of the flue ducts
(door, combustion chamber, smoke
ducts, flue, washers).
– Control the quality of the fuel.
Frequent intervention of the boiler

– Control the presence of air in the
system, the function of the circula-

3.4 ANTIFREEZE PROTECTION
In freezing weather, make sure that
the heating system continues to fun-
ction and that the rooms are kept
warm enough, including the room in
which the boiler is installed; if this
cannot be done, both the boiler and
the heating system must be comple-
tely emptied.
Completely emptying the system also
means emptying the hot water tank
and the hot water heating coil.
3.5 ANTI THERMAL
INERTIA THERMOSTAT
The purpose of the anti thermal inertia
thermostat (TI) is to restart the boiling
unit pump when the boiler reaches

the temperature of 90°C, discharging
the excess heat due to the thermal
inertia of the cast iron body towards
the boiling unit.
The circulator will automatically stop
working as soon as the boiler tempe-
rature falls below 90°C.
3.6
When faults occur and/or the equip-
ment does not operate correctly, turn
it off, without attempting to make any
repairs or take direct action.
For any operation only contact the
authorised technical personnel in your
area.
WARNING: If the LED signal is
missing or the colour changes
(blinking red/green or blinking
red), contact an authorised
technician.
Cause
Normal operation
1. Undervoltage or
Overvoltage:
U<160V or U> 253V
2. Module overvoltage:
T° inside motor too high
Pump cannot restart
itself due to a permanent
failure
1) Pump is not connected
to power supply
2) LED is damaged
3) Electronics are damaged
USER WARNINGS
Remedy
1. Check voltage supply:
195V<U<253V
2. Check water & ambient
