CENTRAL HEATING FAULT FINDING

Upon a demand for Central Heating, (closure of the time clock
and room thermostat, where fitted), the controls should carry out
a set of start up checks, followed by an ignition sequence. Refer
to Section 5.2.
If the control has powered up correctly but does not respond to a
CH demand. Check voltage between pin 2 connector X1A
(orange wire) and pin 2 connector X1B (blue wire). If 0 V ac,
check room thermostat and clock. If 230 V ac, check control for
lockout or blocking codes, (refer to section 8.3), check operation
of the pump.
If room thermostat and clock are OK and no lockout or blocking
code exists and the control is not in anti cycle mode, then

everything should be working correctly, if not contact Halstead
Boilers Ltd Service Help Line: 08450 710780.

Note:

Whenever a CH demand is removed,

either by the timer, the room thermostat or by the
appliance’s internal temperature control, an anti
cycle mode is initiated which prevents the
appliance from firing in CH mode for 5 minutes.
Ensure that the control is not in this mode by
removing power from the control and restoring it
after a delay of 10 seconds.
