Recognising and rectifying faults

In case of a fault, the fault code will flash on the control
panel display. The programming unit shows faults as
plain text messages.
A fault exists if the display flashes and indicates some-
thing other than the current boiler water temperature or
an operating message.
Example: "6A" = the burner will not start
Press and hold down the "Reset" button for about
5 seconds to clear the fault.
The display shows "rE" while the reset is implemented.
A reset is only possible when a fault message is flashing
on the display.
The fault is cleared when the display shows a normal op-
erating message again. Should the fault recur, repeat
the reset two or three times.
If the fault cannot be reset:
Note down the fault message and notify your heating
technician.
