Message Faults Probable causes Action
AL 50 Boiler sensor
The sensor circuit has been broken or
short circuited. The installation is stopped.
Advise the installer.
AL 52 Domestic hot water sensor The sensor is cut
The installation continues to operate but domestic hot
water heating is no longer covered.
Advise the installer.
