too hot.
A-09 Gas pressure
Case 1: Within 5 sec flame, then flame failure.
The flame is not detected. Check the ignition cable and electrode. (cable resistance 1k
•
Ohm).
The electrical earth of the heater is poor,
•
The print board is defective.
•
Case 2:
There is not enough gas pressure.
•
The mixture of gas/air is poor, adjust the gas valve
•
The gas valve does not open, check during ignition for 230V on the valve.
•
Check whether the ignition electrode sparks, replace cable, electrode
•
Case 3: Heat exchanger too hot
Check whether the system fan blows enough air.
•
Check the setting of the gas valve, the heater may me overloaded.
•
Instructions condensing Air heaters type XR version XR-GB-4001-a
Too many errors on heat hot exchanger temperatures
Explanation
Internal error
Overheat heat exchanger sensor
Internal error
Flame detection when that should not be
Internal error
Flue sensor not detected
Flue sensor short circuit
Too many reset actions in a short time
Overheat heat exchanger sensor
Sensor heat exchanger not detected
Heat exchanger sensor short circuit
Supply voltage too low
Supply voltage too hot
Too many pressure switch errors
Flue temperature too high
Appliance temporarily paused, automatic restart will follow
Explanation
Internal error
Heat exchanger hot, heater will reduce power
automatically
Flue gas hot, heater will reduce power automatically
Gas pressure switch open (when mounted)
