6.1 Reading fault codes

If a fault develops in the boiler, the display shows a fault

code starting with "F...".

A plain text display explains the displayed fault code.

Example for F.10: "Short circuit heating feed sensor".

Fault codes have priority over all other displays. If a fault

occurs, then the display no longer shows the current

heating flow temperature.

If multiple faults occur at the same time, then the

display shows the corresponding fault codes for two

seconds each in sequence.

> If your boiler displays a fault code, then contact your

heating engineer.
