Fault Indication - Potterton Performa 24 User Manual

Fault Indication

1. Your Potterton Performa 24 has three neon
indicators. The upper two function as boiler on and
fault indicators.
2. Depending on the nature of the fault the upper two
neons will illuminate, go off or flash.
3. There are five possible combinations, each
indicating one or more fault conditions. These are
described below.
A
The flue or flue terminal is blocked or obstructed in
some way, or there is an internal fault.
If there is no external blockage of the flue that can be
easily removed contact your Installer or Service
Engineer.
B
The circulating pump is faulty or the system pressure
has dropped. Check the system pressure (see page 7).
If the pressure is in the normal range a pump fault is
indicated. Contact your Installer or Service Engineer.
C
A fault on the boiler temperature sensor is indicated.
Contact your Installer or Service Engineer.
D
The primary system or the boiler has overheated.
Allow the boiler to cool. Turn the selector switch fully
anticlockwise against the spring pressure to the 'Reset'
position and hold for at least 3 seconds.
If this occurs repeatedly contact your Installer or
Service Engineer.
E
The burner has failed to light, or incomplete lighting of
the burner has occurred. Turn the selector switch fully
anticlockwise against the spring pressure to the 'Reset'
position and hold for at least 3 seconds.
If this occurs repeatedly contact your Installer or
Service Engineer.
