E00.17 DHW sensor Closed
E01.04 5x Flame Loss Error
E01.11 Fan Out Of Range
E01.12 Return Higher Flow

Description
Return temperature difference is too
large
Domestic Hot Water tank
temperature sensor is either
removed or measures a temperature
below range
Domestic Hot Water tank
temperature sensor is either shorted
or measures a temperature above
range
5x Error of unintended Flame Loss
occurance
Fan speed has exceeded normal
operating range
Return tempearture has a higher
temperature value than the flow
temperature
Solution
Difference between the flow and return tempera­
tures too great:
No circulation:
Vent the central heating system to remove
air
Check the water pressure
If present: check the boiler type parameter
setting
Check the circulation (direction, pump,
valves)
Check that the heating pump is operating
correctly
Check the cleanliness of the heat exchanger
Sensor not connected or incorrectly connected:
Check that the sensors are operating correct­
ly
Check that the sensor has been fitted proper­
ly
Faulty sensor: replace the sensor if necessary
Calorifier sensor open:
Bad connection: check the wiring and connec­
tors
Faulty sensor: replace the sensor
Calorifier sensor short-circuited:
Bad connection: check the wiring and connec­
tors
Faulty sensor: replace the sensor
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 out­
let are not blocked
Check that there is no recirculation of flue
gases
Fan fault:
Bad connection: check the wiring and connec­
tors.
Faulty fan: replace the fan
Fan operates when it should not be operating:
check for excessive chimney draught
Flow and return reversed:
Bad connection: check the wiring and connec­
tors
Water circulation in wrong direction: check the
circulation (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
