alarm 3 - FUME OVERHEATING (HOT FUME)
This is not the same signal as the warning HOT FUME signal. It is triggered when
fume temperature rises above the set threshold, that cannot be changed for safe-
ty reasons. The O-Ring will display the following error through the red leds.
alarm 4 - FUME ENCODER FAULTY
In the event of failure of fume fan or its speed measuring system (RPM), the
fume encoder alarm is triggered displaying the error through the
alarm 5
- FAILED SWITCH-ON
If the heater does not produce a flame within a specified number of minutes and
the fume temperature does not rise, the stove will go in Alarm 5 state, due to
failed ignition.
It is recommended not to put the pellets from the braizer back into the tank
as they may contain burning pellets that may cause the tank to burn into
flames. Put the pellets in a container suitable for flammable material (i.g.
metal bucket).
The O-Ring will display the error through the
RED LEDs.
RED LEDs as follows:
alarm 6
- NO PELLETS (or pellets finished)
It occurs when the stove detects a fume temperature below a set threshold
during operation, a reduction which, if detected in the absence of other errors,
indicates that the pellets in the tank have finished.
The O-Ring will display the relative error by means of the
position shown in the figure.
alarm 7 - SAFETY THERMAL BREAKER OVERHEATING
It is triggered when the safety thermostat probe detects a temperature higher
than the set threshold.
The thermostat blocks the pellet infeed screw and the electronic board detects
the error and blocks the stove; the error is displayed on the O-Ring with 2 red
leds in this position.
