Code Description Solution
E00.20 Flue gas temperature sensor is either removed or
measures a temperature below range
Open circuit in flue gas sensor:
Bad connection: check the wiring and connectors.
Incorrectly fitted sensor: check that the sensor has
been correctly fitted.
Faulty sensor: replace the sensor.
E00.21 Flue gas temperature sensor is either shorted or
measures a temperature above range
Flue gas sensor short-circuited:
Bad connection: check the wiring and connectors.
Incorrectly fitted sensor: check that the sensor has
been correctly fitted.
Faulty sensor: replace the sensor.
E00.40 Water pressure sensor is either removed or
measures a temperature below range
Hydraulic pressure sensor open:
Bad connection: check the wiring and connectors.
Incorrectly fitted sensor: check that the sensor has
been correctly fitted.
Faulty sensor: replace the sensor.
E00.41 Water pressure sensor is either shorted or measures
a temperature above range
Hydraulic pressure sensor short-circuited:
Bad connection: check the wiring and connectors.
Incorrectly fitted sensor: check that the sensor has
been correctly fitted.
Faulty sensor: replace the sensor.
E01.04 5x Error of unintended Flame Loss occurance Flame loss occurs 5 times:
Vent the gas supply to remove air
Check that the gas valve is fully opened
Check the gas supply pressure
Check the operation and setting of the gas valve
unit
Check that the air supply inlet and flue gas outlet
are not blocked
Check that there is no recirculation of flue gases
E01.12 Return tempearture has a higher temperature value
than the flow temperature
Flow and return reversed:
Bad connection: check the wiring and connectors
Water circulation in wrong direction: check the cir­
culation (direction, pump, valves)
Incorrectly fitted sensor: check that the sensor has
been correctly fitted
Malfunctioning sensor: check the Ohmic value of
the sensor
Faulty sensor: replace the sensor
E02.04 Parameter Error Configuration error:
Reset CN1 and CN2
See
The data plate for the CN1 and CN2 val­
ues.
E02.13 Blocking Input of the Control Unit from device
external environment
Blocking input is active:
External cause: remove external cause
Wrong parameter set: check the parameters
E02.15 External CSU Timeout CSU time out:
Bad connection: check the wiring and connectors
Faulty CSU: Replace CSU
E02.17 Gas Valve Control unit communication has exceeded
feedback time
Communication error with the security kernel:
Restart the boiler
Replace the CU-GH PCB
E02.35 Safety critical device has been disconnected Communication fault
Carry out an auto-detect
