...the pellet tank goes in over-temperature
If the pellet container is overheated (>85°C), the pellets will not be loaded because the manual reset thermostat cuts in. If this happens during normal
operation, the appliance switches to "THERMAL SAFETY" alarm. It is therefore necessary to reset the "manual reset thermostat" (see "Components of
the appliance") before switching the appliance on again. To reset, it is necessary to remove the black cap and press the button below.
...lack of power (blackout)
If a power blackout occurs for a shorter time than Pr48, when power is restored, the appliance will immediately re-start in the working mode (recovering
the set working power).
If the outage lasts longer than Pr48, when power is restored, the appliance will enter the "STAND-BY CLE" (stand-by) mode running the entire switch-off
and cleaning cycle until cooling. When this phase is over, the appliance can be restarted resuming work at the set power.

Alarm signals
The following table describes the different alarms which may appear.
DISPLAY VISUALISATION
AL 01 – BLACK OUT
AL 02 – TEMP. F.GAS
AL 03 – REG. ENCODER
AL 04 – NO ENCODER
AL 05 – IGNIT. FAILED
AL 06 – PELLET CHECK
AL 07 – THERM. SAFETY
AL 08 – DEPRESS.-FAILURE
AL 10 – SCREW FEED SAFETY
AL 11 – INSUFFICIENT DRAUGHT
AL 12 – CLEANER FAULT
Every alarm causes the appliance to switch-off immediately. The alarm state is reached after the time set on Pr11
reset by pressing button 3 for a while. In the event of a fault, contact the NORDIC FIRE Authorised technical assistance centre.

Black-out alarm. When power is cut off under determined conditions
Faulty or disconnected flue gas temperature sensor.
This occurs when the speed detected by the flue gas extractor does not correspond with the set
speed.
Flue gas extractor or flue gas extractor encoder faulty. This occurs when the encoder (tachometer)
in the extractor detects an extractor speed equal to 0.
No ignition. This occurs when the minimum temperature in the combustion chamber (Pr13) is not
reached within the maximum ignition cycle time (Pr01).
Sudden shut-down during the work phase. This occurs when, during the work phase, the
temperature in the combustion chamber drops below the minimum threshold (Pr13).
Temperature safety device. This occurs when the safety thermostat (pellet container over
temperature) or the fire door open or not correctly closed cuts in. If the safety thermostat cuts in the
appliance must be manually rearmed (see"Components of the appliance").
Poor depression. This occurs when the flue gas pressure switch cuts in due to poor draught in the
flue pipe or the pellet container door is open.
This occurs when a continuous loading of pellets takes place (the screw feed gear motor does not
stop for at least 0.2 seconds during the maximum work interval of 8.0 seconds). Before the alarm
is activated a safety relay cuts in and forcibly cuts off the power supply to the gear motor.
This occurs when the flow of combustion air is less than the set threshold. NOT USED ON THIS
PRODUCT.
This occurs when the brazier is not correctly aligned during the cleaning procedure (either during
start-up or shut-down).
