12 Troubleshooting
12.1 Identifying and clearing faults
When there is a fault, the fault code will flash on the con-
trol unit display. The programming unit shows faults as
plain text messages.
A fault is present if the display flashes and indicates
something other than the current boiler water tempera-
ture or a message related to standard operation.
Example: "6A" = burner does not start
Please refer to the control unit's
documentation for an
overview of fault and service codes, as well as possible
causes and remedial measures.
B
Press and hold down the “Reset” button for about
5 seconds to clear the fault.
The display shows "rE" whilst the reset is being imple-
mented. The reset is only possible if a fault message
flashes.
If the display then reverts to a standard operating mes-
sage, the fault has been cleared. Should the fault recur,
repeat the reset two or three times.

pipework at the lowest possible point.
