Well, that's not entirely true, I can if I switch everything off!
System - as far as I can tell
- Danfoss CP15C controller
- Danfoss WB12 wiring thingy
- Danfoss T45? valve?
- Danfoss Thermostat
- Grundfos Selectric pump
- HRM Wallstar oil-fired boiler
Stuff that works
- When I just switch the CH on at controller it comes on fine in conjunction with thermostat
Stuff that doesn't work
- When I switch on just the HW at controller, CH comes on too, regardless of thermostat setting.
I can find no way of having just the Hot Water come on by itself.
Any help would be very much appreciated.
