I've been trying to wire up my new boiler (baxi combi duo tec 28) with my existing drayton 522 programmer and digistat 1 thermostat.
I have one question I'm hoping you can answer:
I've got power to the programmer and and boiler both off a 3A mains supply. Terminal 4 on the programmer (CH on) is wired to the common on the digistat, the call for heat on the digistat is wired to the switched return on the boiler. My question is where does the wire (switch out) from the boiler go that completes the loop as per the manual? I believe it should go the the programmer but don't know which terminal it should go to?
Terminal on programmer as follows:
N
L
1 (hw off)
2 (ch off)
3 (hw on)
4 (ch on)
Help needed!
