WAIT FOR COOL.
A new ignition is attempted when
the boiler has just been switched
o (normal switch-o or caused by
an alarm).
When the stove switches o (normal or caused by an
alarm) it is necessary to wait until it cools down completely,
therefore clean the brazier.
The boiler can only be re-ignited successively.
STBY / TOFF
The rear input (STBY) is satis ed and
the boiler is waiting to re-ignite.
See description of “External thermostat function in STBY/
TOFF” mode.
To exclude this function press key 1 to take the boiler to OFF
and disconnect the external thermostat from the boiler.
T1 FLASHING.
Indicates that input ING1 is
satis ed.
See description of“Mode” chapter.
T2 FLASHING.

satis ed.
See description of“Mode” chapter.
HOFF
The temperature of the water has
exceeded the set threshold by
more than 5°C.
The water has reached a
temperature of 85°C.
Check the correct functioning of the hydraulic plant.
On lowering of the water temperature (5° below the set
threshold) the machine will re-start in automatic mode.
TOFF
The 2 rear inputs (INP1 and INP2)
are both satis ed (contacts open).
Check the status of the 2 rear inputs (ING1 and ING2).
If 1 of the 2 external thermostats is no longer satis ed
(contact closed), the boiler will go back to ignition in
automatic mode.
To exclude any boiler re-ignition just hold down button 1
for 3 seconds, taking the boiler to OFF.
BLACK OUT COOLING
No current on the main power
supply.

automatically.
CLEANING The boiler is cleaning the pot.
The automatic brazier cleaning is accompanied by this
signal on the display.
EXCHANGER
CLEANER BLOCKED
Automatic cleaning of the springs
blocked.
It is not an alarm, therefore the boiler continues with normal
functioning. If automatic cleaning is blocked the display
shows this signal and the working status of the boiler
alternately.
The automatic system restore operations must be carried
out by an authorised technician.
