12.2 SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the
preset value.
12.3 CONTACT THERMOSTAT IN THE FUEL HOPPER
If the temperature exceeds the preset safety level, it immediately shuts down boiler operation.
12.4 ELECTRICAL SAFETY
The product is protected against sudden current surges by a main fuse in the power supply panel on the rear part of the product.
Other fuses that protect the electronic boards are found on the latter.
12.5 SMOKE FAN
If the fan stops, the electronic board promptly shuts off the pellets supply and an alarm message is displayed.
12.6 GEAR MOTOR
If the gear motor stops, the boiler will continue to run until the flame goes out due to lack of fuel and until a minimum level of
cooling is reached.
12.7 TEMPORARY POWER CUT
If the power cut lasts less than 10" the boiler returns to its previous operating status; if it lasts more it carries out a cooling/restart
cycle.
12.8 FAILED START-UP
If during ignition no flame develops, the boiler will go into alarm condition.
12.9 BLACKOUT WITH THE BOILER ON
In the event of a power cut (BLACKOUT) the boiler behaves as follows:
• Blackout below 10": it returns to its operation in progress;
• In the event of a power cut that lasts over 10" with the boiler on or in the start-up stage, when the boiler is powered again it
goes back to the previous operating condition with the following procedure:
1) It performs a cooling phase to the maximum.
1) Performs a new ignition.
During stage 1 the panel displays ON BLACK OUT.
During stage 2 the panel displays Start-up.
If during stage 1 the boiler receives commands from the panel and thus carried out manually by the user, then the boiler stops
executing the blackout recovery status and proceeds to restart or shutdown as requested by the command.
