Full instructions on how to install and operate the optional facia-
mounted programmer are included with the programmer kit.
If your boiler operates on gravity feed, the system will only
function correctly on heating if the programmer switches on the hot
water programme at the same time. To ensure that this is always the
case, the programmer is supplied with a gravity system switch on the
rear of the unit; this switch must be set to G by your installer.
The programmer gives fully independent programmes for
central heating (CH) and hot water (HW) when the switch on the
rear of the unit is set to P and the boiler is installed with a fully-
pumped system.
Many calls made to Worcester Heat Systems to report boiler
faults or breakdowns prove to be false alarms, as there is often a
simple explanation for the apparent malfunction.
So, to help you save time and money - not to mention
frustration and inconvenience - a quick-reference fault finder is
included on page 8.
If, after checking through the points suggested, there is still a
fault you should call your local Worcester Heat Systems Service
Centre. Arrangements will be made for an engineer to call as soon
as possible.
CALL-OUT CHARGES
All of Worcester Heat Systems’ field service engineers are
factory trained.
If you request a visit from an engineer and your boiler has been
installed within the last 24 months, no charge will be made for
parts and/or labour providing:
●The appliance was commissioned correctly on installation
and a completed Guarantee Registration Card returned to
Worcester Heat Systems.
●An appliance fault is found and the appliance has been
installed within the past 24 months, provided that the first
annual service has been carried out on a boiler which is more
than 12 months old. Reasonable evidence of this must
be supplied on request.
