Changing room thermostat.

GARYF123 · 23 Dec 2009

Hi, can anybody please help?

I have a WB combi boiler. The system has a Potterton PRT2 room thermostat and is using TRV'S. I have purchased a Salus EP200 digital 2 channel programmer but am unsure of wiring. The old Potterton has the following terminals;

2 com
3 H stat switched live
4 TL timed live
5 neutral

The new digital 2 channel programmer (Salus EP200) has the following terminals;

N
L
1 (HW OFF)
2 (CH OFF)
3 (HW ON)
4 (CH ON)
Earth

Can anybody advice on correct connection please?

Many thanks in advance,

Gary.

You only need a 1 channel programmer.
