ERROR CODE LIST
Error code
Description
Possible cause
Loc 2
Flame failure at the end of the safety time
- Faulty or dirty fuel valves - Faulty or dirty flame
detector - Non-optimal burner setting, lack of fuel
- Faulty ignition device
Loc 3
Air pressure error (air pressure switch stuck
in rest position, drop after specific time)(air
pressure switch signalling time)
Air pressure switch error - Air pressure drop after
the specified time - Air pressure switch stuck in
rest position
Loc 4
Extraneous light
Extraneous light upon burner start-up
Loc 5
Air pressure error, air pressure switch stuck in
operating position
Air pressure switch time control - Air pressure
switch stuck in operating position
Loc 7
Flame loss
Too many flame losses during operation
(limitation of repetitions) - Faulty or dirty fuel
valves - Faulty or dirty flame detector - Non-
optimal burner setting
Loc 10
Unassigned error (application), internal error
Wiring error or internal error, output contacts,
other faults
Loc 12
Seal control
Fuel valve 1 is leaking
Loc 13
Seal control
Fuel valve 2 is leaking
Loc 14
POC error
POC valve closing control error
Loc 22
Safety circuit
- Gas pressure switch-max open - Temperature
safety limiter has been triggered
Loc 60
Analogue power source 4-20 mA, I<4 mA
Broken wire
Loc 83
PWM fan error
- PWM fan does not reach the target rpm
within the specified time or, after reaching the
target rpm, it stays outside the tolerance range
(parameter 650) after the tolerance time for rpm
discrepancy (parameter 660) has elapsed
Loc 138
Restore process successfully completed
Restore process successfully completed
Loc 139
PME7 has not been acknowledged
No PME7 has been inserted
Loc 167
Manual lockout
Manual lockout
Loc 206
AZL2 is incompatible
Use a new version
Loc 225
PWM fan error
- After reaching the pre-ventilation rpm, pre-
ventilation PWM has fallen below the minimum
limit (parameter 675.00) or, after reaching the
ignition load rpm, the maximum ignition load
PWM has been exceeded (parameter 675.01)
Loc 226
PWM fan error
Parametrization error - minimum load rpm >
nominal load rpm or minimum load = 0 rpm or
maximum rpm = 0 rpm
Loc 227
PWM fan error
One or more parameters exceed the minimum/
maximum limit
rSt Er1
