active for longer than six minutes.
1. Maximum thermostat (STB) has
reacted
The lead temperature has exceeded its
set value. Wait until the lead tempera-
ture is below the set value for at least
one minute, then unlock the safety
function by pressing the reset button.
2/3. Blocking entrance has been
interrupted
An external safety, connected to the
clamps (ST 9.3-9.4) has reacted.

When starting combustion, no flame
was detected during the set safety
period. If the corresponding program-
ming has been undertaken, a new start
is possible.
5. Flames reduce during operation
While the burner is in use, the
respective ionisation flow was below
1 µA.
Check and unlock this safety function
by pressing the reset button.
6. Maximum temperature monitor
(STW) has reacted
The lead temperature has exceeded
the value set for it or the water flow is
too weak.
7. Maximum smoke gas thermostat

o
C
.
Remedy the fault
and activate Reset.
11. Wrong flame signal
An ionisation flow exceeding 1 µA has
been measured while the burner is in
use.
Remedy the fault and activate Reset.
12. Defective lead temperature
sensor
The measured resistance of the
temperature sensor is outside the
range between -10 and +126
o
C
.
Remedy the fault and press Reset.
13. Defective smoke gas temperature
sensor / locked entrance has been
interrupted
The measured resistance of the smoke
gas sensor is outside the range

C
.
Remedy the fault and press Reset.
20/21. Error in the gas valve control
After the burner has been switched off,
no ionisation flow bas been measured
for 5 seconds, which was greater than
1 µA. Remedy the fault and press
Reset.
24. Wrong minimum blower speed
When rinsing, a specific minimum
bower speed is not achieved. Remedy
the fault and press Reset.
25. Defective maximum blower
speed
A specific maximum blower speed has

When the blower is switched off, the
selected speed is too high
(300 revolutions / minute).
Remedy the fault and press Reset.
30. CRC error in the control
parameters
An Eeprom error has occurred in the
stored control parameters. Check and
change this parameter set.
31. CRC error in the safety-relevant
parameters
An Eeprom error has occurred in the
stored safety-relevant parameters.
Check and change this parameter set.
32. Faults in the low voltage power
supply
The low voltage power supply is too
small or the fuse is defective. Remedy
