TROUBLESHOOTING

Maintenance operations must be carried out by an au-
thorised company (e.g. Authorised Technical Assis-
tance Service).
There can be three possible causes for this anomaly:
Red pump LED
Trouble
Low power supply voltage
Rotor seized
Electrical error
Trouble
Smell of gas
Repeated ignition blocks
Irregular combustion or
noisiness
Non-optimal ignition of
first ignitions of the
burner.
Frequent trips of the
overheating safety device
thermostat function.
Siphon blocked
Condensing heat
exchanger clogged
Abnormal noises in the
system
Abnormal noises in the
condensation module
Possible causes
After about 2 seconds, the LED switches
from green to red and the pump stops.
Powering the pump with the rotor seized,
after about 4 seconds the LED switches
from green to red,
Possible causes
Caused by leakage from gas circuit pipe-
lines.
No gas. Condensate drain clogged.
Dirty burner, clogged primary heat ex-
changer, incorrect combustion parame-
ters, intake-exhaust terminal not correctly
installed.
The first ignitions of the burner (after cali-
bration) may not be optimal.
Lack of water in the boiler, poor water cir-
culation in the system or blocked circulat-
ing pump (Par. 1.29 , 1.30).
Dirt or combustion products deposited in-
side.
Siphon and/or duct between condensing
exchanger and siphon clogging.
Air in the system.
Air in the module.
Wait for the power supply voltage to rise; when the pump restarts, the LED
will turn green again with a delay of about one second. Note: The flow rate
decreases as the supply voltage decreases.
Carefully act on the screw in the middle of the head to manually release
the crankshaft; circulation starts up immediately after the rotor is re-
leased and the LED switches from red to green after about 10 seconds.
Check that there is no fault on the pump (on its wiring or electronics).
Check sealing efficiency of gas intake circuit.
Check the presence of pressure in the network and that the gas adduction
cock is open. Restore/release the function of the condensate drain, check-
ing that the condensate has not affected: combustion components, fan
and gas valve. Check the function of the condensate sensor.
Check the indicated components.
The system automatically adjusts the burner ignition until the best igni-
tion conditions are found.
Check on the pressure gauge that the system pressure is within estab-
lished limits. Check that the radiator valves are not closed and also the
functionality of the pump.
Check that there are no residues of material blocking the flow of conden-
sate.
Check that there are no residues of material blocking the flow of conden-
sate.
Check the opening of the cap of the air vent valve (Par. 1.32). Make sure
the system pressure and expansion vessel pre-charge values are within the
set limits. The factory-set pressure values of the expansion vessel must be
1.0 bar, the value of system pressure must be between 1 and 1.2 bar.
Use the manual air vent valve (Par. 1.32) to eliminate any air present in
the condensation module. When the operation has been performed, close
the manual vent valve.
