Hello, I need some help please with wiring my CH and DHW.
What I hope to achieve is a system whereby I can program both my CH and DHW independently, both times and temperature. Previously I had just the option of CH + DHW or DHW only. I only had 1 x 2 port valve but am going to fix a second to allow CH to be off when DHW is on - primarily to reduce the temp of the DHW and hopefully reduce oil usage!
i.e. CH set to temp of boiler (say 70 degrees) and controlled by programmable room stat and DHW to be heated to a set temp controlled by timed program and cylinder stat (60 degrees or lower)
The components I have are
1 x Salus EP200 2 channel programmer
(Connections are N , L , 1 HW OFF, 2 CH OFF, 3 HW ON, CH ON, Earth)
1 x Salus RT500RF wireless programmable room thermostat
(Connections are NO ,COM, L , N)
1 x Salus CT100 cylinder stat
(Connections are NO ,COM, L , N)
1 x Salus TC100 wiring centre
1 x 2 port motorised valve with 3 connections N, L & E
1 x 2 port motorised valve with 5 connections N, L , E , C – CH Call, CH (NO)
Feed to the oil boiler and pump wired to both be on at the same time from the same N & L feed
I had hoped the wiring centre would make life easier but all the wiring examples I’ve looked at have confused me particularly as they all show the 2 port valves as having 5 connections when my original one, controlling CH, has only 3!
I’m hoping this is a simple wiring job for the experts here and that some of you kind folks will point me in the right direction.
Thank you
