Introduction

The programmer will automatically switch your central

heating and hot water on and off at times that suit you.

The green light on the front of the programmer shows

when each one is on. LP20RF has a 7-day program

allowing for different timings on each day of the

week, with central heating and hot water working

independently for up to 3 heating periods each day.

If the engineer hasn’t set your timings for you, your

programmer will work with a standard program that has

been set at the factory. If this doesn’t suit you, it’s very

easy to change it.

NOTE:

Advance has no effect with constantly on

or off is selected on the receiver or when

there is no demand from the transmitter.
