Troubleshooting
Faults, recognising and rectifying
In the event of a fault, the fault code will flash on the
control unit display. The room controller shows faults as
plain text messages.
A fault is present if the display flashes and indicates
something other than the current boiler water temperature
or a message related to standard operation.
Example: "6A" = burner does not start
A list of the fault codes and the possible causes and
remedies can be found in the control unit documentation.
V
Press and hold down the "Reset" button for about
5 seconds to clear the fault.
The display shows "rE" whilst the reset is implemented.
The reset is only possible, if a fault message flashes.
Fig. 77 Clearing a fault with the reset button
If the display then reverts to a standard operation
message, the fault has been eliminated. Should the fault
recur, repeat the reset two or three times.
