Operating instructions

OPERATING YOUR

PROGRAMMER CONTROLS

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 tis is always

the case, the programmer is supplied with a gravity system on the

rear of the unit; this must be set to G by your installer.

The programmer gives fully independant 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.
