Troubleshooting
Heating system faults are shown on the control panel display. You will
find detailed information regarding fault displays in the service
instructions for the relevant control panel. The burner fault is also
indicated by a fault lamp on the burner.
NOTICE: Risk of system damage from freezing.
▶ The system can freeze if it is out of service, e.g. power
failure, shutdown caused by fault(s).
▶ If the system remains switched off for several days
because of a fault shutdown, you should drain the
heating water via the boiler drain valve at the lowest
point in the system to protect it against freezing.
▶ Press the burner reset button (see burner operating instructions).
NOTICE: Risk of system damage due to too many resets.
▶ The burner ignition transformer may be damaged if
you press the reset button more than three times in
succession when the burner refuses to start.
▶ Do not attempt to remedy the fault by pressing the
reset button more than three times in succession.
If the burner does not restart after three attempts, refer to the technical
documentation provided with the burner to find out how to reset it.
