HI Guys,
I bought a new house and wanted to change the old time clock on the boiler to a c27 programer so I could have different settings for each day. There are no thermostats on the system just a 2 port valve which I think is a spring return.
The boiler fires when I turn on the HW channel and the valve opens when I turn on the CH channel or at least is supposed too.
The valve opened and all the radiators worked before I changed the programmer, so I must have the wiring wrong, although it seems straight forward as I both programmers said HW on, HW off and so on.
Heres the way I connected it
terminal L - mains live
terminal N- All neutrals from valve,boiler and mains
terminal 1-not used (HW off)
terminal 2- not used(CH off)
terminal 3- live to boiler(HW on)
terminal 4- live to valve(CH on)
Anyone have anys ideas any help would be great!
