The Control Panel has a 3 digit display, during normal
operation the display will show one of three things on the
two right hand digits;
During Stand-by (no demand for Central Heating or D.H.W.)
'on' will be shown on the display and no LEDs will light.
During a demand for Domestic Hot Water, the temperature of
the outgoing hot water is displayed in
summer mode LED will light (F - F
During a demand for Central Heating, the temperature of the
central heating flow will be displayed in
central heating mode LED will light (H - F
During the operation of the flue analysis mode* the
display will show 'sc'.
Should a fault occur the display will show the fault code
and one of two letters, for a non-volatile shutdown the
letter 'A' will be shown followed by the two digit code for
the fault eg. 'A02' and the red LED (G - F
light, a non-volatile shutdown will require the reset button
(D - F
. 2.22) to be pushed before the boiler will attempt
IG
to relight, should the boiler lockout again, the assistance
of an Authorised Service Engineer should be sought.
Should the boiler develop a fault that cannot be corrected
by resetting the boiler, the letter 'E' will be displayed
followed by a two digit code (e.g. E33) indicating a
volatile shutdown code, in the event of such a shutdown,
the boiler will automatically resume operation once the
cause behind it is resolved. Should it not the assistance
of an Authorised Service Engineer would be required.
A list of the fault codes can be found opposite.
