Possible cause: The temperature of the pellet flexible filling
tube on the burner is higher than 80° C.
Boiler status: Currently goes to OFF mode.
Troubleshooting: Possible fulfilling of the burner furnace and
flexible tube due to incorrectly adjusted combustion air,
incorrectly tuned delivery parameters, inadequate dimensions
or pellet quality, possible hole on the flexible tube or fall of the
flexible tube from the delivery tube, possible fan stopage,
possible impassable flue gas passages in boiler and chimney.
Possible cause: Break in the cables between the sensor and
control, control contacts, cold connection or defective boiler
sensor.
Boiler status: departure to shutdown mode.S7 (S7-1).
Troubleshooting: Call an authorized service person to check
the sensor location in the tank, check for sensor/cable damage,
check connections at the connectors, check the ohmic
resistance of the sensor.

Boiler status: Currently goes to OFF mode.
Troubleshooting: Check that the fault is caused by the loss of
pellets (in the tank/transporter), the congestion of the
transporter motor, the spiral of the transporter, the foreign body
in the transporter, the improper supply, the supply of too humid
pellets, the burning of the burner grate to the remains of pellet
combustion or the scorching of the photocell.
Possible cause: The photocell does not see the flame during
the burner operation in the burner furnace, before which the
current has disappeared in one of the burner stages except
"OFF", "A0" and "S7-3".
Boiler status: departure to shutdown mode S7 (S7-1).
Troubleshooting: Check that the fault is caused by the loss of
pellets (in the tank / transporter), faulty feeding ,feeding of the
