LAMBDA CALIBRATION
if calibration out of range or if other
error occurs during calibration and
aborts

Standard Fuels
if
1) Pre-filling / Ignition insert cannot
be performed because no fuel
2) Failure “FIRE OUT” occurs for the
second time within 2 hours.
3) during operation intermediate
hopper is not full despite power
reduction
Check fuel level
Check burning parameters, adjust
as adapt
Clean intermediate hopper level
sensor
System must be started manually
077
Additional input
Additional input (e.g.: system
pressure, CO-sensor) active
Check failure at additional input
aggregate
078
NIVEAU LEVEL
Active intermediate hopper level
sensor; low fuel level at intermediate
hopper
Check fuel level
Check discharge system (motor,
screw, springs)
080
MP ROOM DISCHARGE
Digital input motor protection room
discharge has responded
Check discharge system (motor,
screw, springs) to debris
088
BACK FLOW SET PWM
CAN communication to the PWM-
module was interrupted or the
module was not found
*Check connection module CANBus
*Check module
✆ - contracting party
089
E-Filter
if external E-Filter:
*Digital input E-filter has responded
if external E-Filter:
*Fault at HV-Modul
*Fault at cleaning
*Check E-Filter
at internal E-Filter:
*see functional description E-Filter

ERROR ASH
DISCHARGE
Ash discharge did not clean 3 times
repeatedly; ash container full; debris
block ash screw; motor defect
Empty ash container
Remove debris
093
ENDSWITCH ROOM
DISCHARGE
Digital input Room discharge
system end switch active has
responded
*Check discharge system (screw,
...) to debris / blockage
096
BURNER STOP
Digital input burner stop has
responded
*Boiler is in the state "Boiler Stop"
*contact open
097
Backup config
Fault when loading backup

Floor temp. WARNING
at external monitoring:
*Digital input temperature ash floor
has responded
at monitoring via CAN:
*a sensor has exceeded the limit
value
▪ check the parameter
101
Floor Temperature fault
Error 101 (floor temp. warning) is
continuously active for 3 hours
during the burning process
▪ check the parameter
103
RECI mixing temperature
Sensor break; Value outside the
measuring range
(-10 - 120°C)
Check sensor, replace as renew
Check plug, replace as renew
Check wiring incl. connections,
replace as renew

Boiler spreading
Boiler spread too low at nominal
load (less than 8K)
▪ Reduce pump speed (step) to get
more spread
