1,9 Running
The running of the appliance is controlled from a control panel with a microprocessor which programmes the following phases:
– When a request for heat is sent in start-up mode the main fan, the external cochlea and the internal loading cochlea start up to
supply the necessary quantity of pellets for ignition. The internal cochlea starts up 8 seconds later than the external cochlea;
– When the pellet loading for ignition is finished, the ignition resistance is powered electrically, and this ignites the flame the
brightness of which is recorded by the photocell within a max. of 20 minutes (safety time). In the event of non-ignition, the bur-
ner goes into SHUTDOWN mode. In the event of a SHUTDOWN, in order to reactivate normal running conditions, it is necessary
to disconnect the appliance from the mains, remove the cause of the malfunction, and then reconnect it to the power supply;
– After the flame has been correctly detected, the appliance starts to run normally with a gradual increase in power supply until
the maximum value programmed is reached, and the appliance continues to operate in modulation until the programmed water
temperature for the boiler is reached, or that of a water storage heater if one is installed. While the burner is running, the exter-
nal and internal cochleas also work according to the programmed ON and OFF times;
– Once the programmed temperature has been reached, the cochleas, both internal and external, are stopped by the control
panel, and the pellets remaining in the combustion chamber continue to burn;
– When the brightness of the photocell goes below 20 lux, the fan speed increases to clear the combustion chamber of the last
residue and then it stops.
The burner is then ready for the next start-up.
WARNING CAUTION
– The programming of the parameters MUST be carried out EXCLUSIVELY BY QUALIFIED TECHNICIANS AUTHORISED BY only
after the Password has been given.
– For the working and shut-down periods of the burner, whether the "time bands" are activated or not should be taken into consi-
deration.
– If the COMPRESSED AIR KIT is also present, cleaning of the combustion chamber takes place at the beginning and at the end of
each operational cycle of the burner.
