(lock out error)
Flame error
Too many flame failures
are detected
Recirculating flue gases due too
incorrect roof or wall flue terminal. Make sure the flue terminal is installed
correctly, refer to Venting system (see
section 8.7). If necessary, connect the
correct flue terminal.
Make sure that the terminal is installed
correctly, refer to Venting system (see
section 8.7). If necessary connect the
flue terminal correctly.
Make sure that there are no flue gas
leaks to the rest of the venting system.If
necessary reconnect the venting system
and replace any damaged seals.
Make sure that the flue terminal
discharges into a permitted area.
Make sure that the CO
2
-value measured
in the flue gas outlet is correct, refer to
CO
2
value (see section 8.9.4).
Make sure that the CO
2
value measured
in the air inlet is below 0.5 vol%.
If necessary, reconnect the venting
system and change the necessary seals.

No sufficient gas supply. Make sure that the gas supply (see section
13.3) pressure is correct.
F07
(lock out error)
Ionisation error
Ionisation measured after
the gas control valve was
closed
Defective gas control valve. Make sure that there is no flame after the
gas control valve has closed.
If there is a flame, the gas control valve
must be replaced. •

F08
(lock out error)
Ionisation error
Ionisation measured
before the gas control
valve was opened
Defective safety relay. Reset the controller.
If error appears again, replace the
controller. •

F09
(lock out error)
Temperature error
Temperature, in the tank is above the
97ºC. See measure of error
E01
.
Make sure that the wiring between 1 and
7 of J9 is connected and not damaged.
If necessary, replace or reconnect the
wiring.
When the wiring is reconnected, reset the
controller.

F11
(blocking error)
Ionisation error
Ionisation measured with
a closed gas control valve
Defective gas control valve. Make sure that there is no flame after the
gas control valve has closed.
If there is a flame, the gas control valve
must be replaced. •
•
F19
(blocking error)
Supply voltage error
There is not enough or too much supply
voltage present, during 60 seconds.
The measured voltage must be 230 V
AC
(-15%, +10%).
Make sure that the supply voltage on the
controller is correct.
If the supply voltage is above or below
the stated tolerance and the error
persists, contact your maintenance and
service engineer. •

F21
(lock out error)
Air proving switch error
Switch is not closed, while
fan runs during post purge
Damaged wiring/open circuit. See measure of error
F03
- Switch is not
closed when fan is running during pre-
purge.
