Operating instructions

Full instructions on how to install and operate the optional facia-

mounted programmer are included with the programmer kit.

Your boiler is designed to operate on a fully pumped system only.

The programmer gives fully independent programmes for cen-

tral 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.

Ensure that your installer sets the switch to P on the back of the

programmer.

Many calls made to our Contact Centre reporting 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 frustra-

tion 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 our Contact Centre. Arrangements will be

made for an engineer to call as soon as possible.

CALL-OUT CHARGES

All of Worcesters’ 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.

 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.
