Errors
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.
E3
PELLET SUPPLY TUBE
TEMPERATURE
TOO HIGH
E4
INCORRECT BOILER
SENSOR
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
man
to check the sensor
location in the tank, check for sensor/cable damage, check
connections at the connectors, check the ohmic resist
.
of the sensor.
E5
INCORRECT DHW
SENSOR
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).
If the user
turns off the DHW fault stops and the boiler can start.
Troubleshooting:
Call an authorized service
man
to check the sensor
location in the tank, check for sensor/cable damage, check
connections at the connectors, check the ohmic resis
t.
of the sensor.
E6
FLAME LOSS WHILE
WORKING
Possible cause:
The photocell does not see the flame in the burner
furnace.
Boiler status:
Currently goes to OFF mode.
T
roubleshooting:
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.
E6_1
FLAME LOSS AFTER
POWER FAIL
Possible cause:
The photocell does not see the flame during the
burner operation in the burner furnace, before which the current has
disappear
.
in one of the burner stages except "OFF", "A0" and "S7-3".
B
oiler 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 too humid
pellets, the burning of the burner grate to the remains of pellet
combustion or the scorching of the photocell. Clean grate and burner.
E7
WRONG
DATE AND TIME
Possible cause:
Low or fully charged battery. Clock reset at 00:00 and
date on 1.1.2000. after switching off or unplugging (or not configured),
and at least one switching time
(boiler/DHW/recirculation) is switched
on. If no switching time is on, this error will not occur, but Warning W2.
This burner failure can not be detected by itself, it can only occur if a
switch-on time is triggered in the work while we have a W2 warning, in
which case the burner goes into the S7 (S7-1) shutdown phase. If any
currents, during the burner operation (all stages except "OFF", "A0" and
S7-3) are disconnected, then the current is returned and the E7 is
acknowledged, the boiler will perform the necessary actions after power
failure and will not start due to mistakes. If the currents are gone when
the burner is in the "OFF", "A0" and "S7-3" stages, and then the
currents return to the E7, the boiler will not start due to an error.
Boiler status:
The boiler can operate, if all the switching times are off,
otherwise it can not operate. The boiler states under different
circumstances are described above
„Possible cause“.
Troubleshooting:
It is necessary to replace the battery (CR1220) on
the control panel PC board.
