39 Troubleshooting

39.1 General information
Never remove, bypass or otherwise disable any safety or monitoring equipment. Only operate the heat pump in perfect
technical condition. Any faults or damage which impact or might impact upon safety must be remedied immediately
by a qualified contractor. Replace faulty components and equipment only with original WOLF spare parts.
Faults are shown in plain text on the display of the control accessory – AM display module or BM-2 programming unit
– and correspond to the messages listed in the following tables.
A fault symbol (triangle with exclamation mark) on the display indicates an active fault message. A padlock symbol
indicates that the current fault message has caused a lockout of the heat pump. The display also shows how long the
message has been active.
Faults must only be rectified by qualified personnel. If a fault message is acknowledged several
times without the cause of the problem being repaired, this can lead to component or system
damage.
The control unit automatically acknowledges faults such as faulty temperature sensors or other
sensors if the part concerned has been replaced and plausible test values have been supplied.
