E13
Communication error with
sensor board
Boiler status:
Boiler go to phases
S7, C0
and
OFF
.
Possible causes
:
Call service man!
E14
Lambda probe error
a)
Error occurs in the phase of "OFF" The problem is with
el. heater which is integrated into the lambda probe
b) Error occurs in all phases except "OFF”
The problem is with the communication system within
the lambda(Cables, connectors, el. boards, software)
E16
Communication error with
CM2K module (1st and
2nd circuit)
Boiler status:
Boiler work normally.
Possible causes
:
Interruption in el. connections between
boiler and CM2K (between two CM2K’s), connection on
boiler and CM2K (or two adjecent CM2K’s) or CM2K
module is invalid.
E17
Sensor CM2K 1. circuit
Boiler status:
Pump of 1+ heating circuit doesn't work.
Boiler work normally.
Possible causes
:
Error on flow temperature sensor of 1+
heating circuit (on regulator CM2K).
E18
Corrector CM2K 1. circuit
Boiler status:
Pump of 1+ heating circuit work in
intervention mode by heating curve. Boiler work normally.
Possible causes
:
Error on room corrector of 1+ heating
circuit (CM2K regulator), bad corrector connection to the
CM2K or room corrector failure.
E19
Sensor CM2K 2. circuit
Boiler status:
Pump of 2+ heating circuit doesn't work.
Boiler work normally.
Possible causes
:
Error on flow temperature sensor of 2+
heating circuit (on regulator CM2K).
E20
Corrector CM2K 2. circuit
Boiler status:
Pump of 2+ heating circuit work in
intervention mode by heating curve. Boiler work normally.
Possible causes
:
Error on room corrector of 2+ heating circuit (CM2K
regulator), bad corrector connection to the CM2K or room
corrector failure.
E24
Boiler status:
Boiler work normally.
Possible causes:
Interruption on el. connections between
room corrector and boiler, connection to the boiler or room
corrector is invalid.
Room corrector
E22
Flue gas temperature too
high
Boiler status:
Boiler goes to phase „OFF”.
Possible causes
:
Flue gas tubes are dirty (wood side),
invalid flue gas sensor, bad sealing, open middle boiler door
(wood side).
E12
Communication error with
motherboard
Boiler status:
Boiler immediate go to phase OFF.
Possible causes
:
Call service man!
E26
Boiler status:
Boiler work normally.
Intervention mode:
Boiler work to content heating demand
but boler has reduced possibilities.
Possible causes:
Interruption on el. connections between
firebox sensor and boiler or bad connection to the boiler.
Firebox sensor
disconnected
