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.
