dispensing of pellets stops and the flue gas motor and ambient fan are operating at maximum capacity in order to cool the
oven as soon as possible. Minimal duration of the shutting off phase is 30 seconds, and the condition for the furnace to
cool down completely is for the temperature of flue gases to be less than 68°C.
4.5.8
OFF
In this state, the furnace is turned off i.e. no output on the furnace (flue gas motor, ambience fan, lighter and auger) is
active.
4.5.9
Block
The blockage condition occurs in the event of error or alarm. In the block mode, the fan of the exhaust gases, auger and
lighters are off. To exit, hold P2 pressed for 3 seconds: if it is no longer blocked and there is no cause for alarm, the system
will shut down.
4.5.10
Ignition Recover
The furnace moves to this phase in two cases:
5
If a power failure occurs during the operating mode and the flue gas temperature is higher than 50°C.
6
Pressing the main switch at the moment when the furnace is in the shutting down phase.
Other functions
4.6.1
Voltage shortage management
In the event of power failure, the system keeps the most important functional data. With the return of the voltage, the
system assesses the saved data and:
If the furnace is turned on and the temperature of the exhaust gases is higher than 50°C, the system switches to
the Ignition recovery. By pressing the P1 button, a sudden new ignition of the system is possible.
If the furnace is on, but the temperature of exhaust gases is less than 50°C, the system enters shutdown with
error Er15.
If the furnace is switched off or during shutting off or while blocked, the system returns to its previous state.
In the absence of voltage over a period of one week, the system becomes blocked with an error message Er11
indicating that the DATE / TIME is not accurate. Deblock using the P1 button, the value of TIME flashes, signalling the need
for updating the TIME and DATE with the function CLOCK.
4.6.2
Pellet feeding calibration management
The user has the possibility to calibrate the dosing of pellets in the User menu 1. Calibration range from -7 ÷ 7. 1=5%.
Each calibration of the pellet dosing is applied percentually to all work powers. E.g. if set to -1 then the pellet dosing would
decrease by 5% in all operating modes (Power 1 - 5).
Example

Power 1 =
2.0
Power 2 =

Power 4 =

Power 5 = 5.7
Never calibrate the pellet dosing without consultations with the repair shop.
4.6.3
Managing the correction of the flue gas motor
The user has the possibility to calibrate the speed of flue gases motor in the User menu 1. Calibration range from -7 ÷ 7.
1=5%. Each calibration is applied percentually to all work powers. E.g. if set to 3 then the flue gas motor speed would
increase by 15% (3x5%) in all operating modes (Power 1 - 5).

Never calibrate the speed of flue gas motor without consultations with the repair shop.
4.6.4
Safety thermostat
In case the temperature of the pellets in the tank reaches a value greater than 90°C, a safety thermostat is activated in
order to prevent the ignition of the pellets in the tank. The system moves to the blockage mode of work and the alarm
message Er01 appears.
4.6.5
Periodical cleaning of the furnace
When the system is in stable condition, after a specified time interval (every 45 minutes), the system automatically
performs periodic cleaning for 30 seconds.
During the periodic cleaning, the flue gas motor works with increased intensity and the dosing of pellets stops.
