Hi,
I'm renovating a few rooms, one of which contains a very old central heating controller:
I'd like to replace this. The wiring looks fairly normal, with one output for "heating on" and another "hot water on".
Can I put a new controller on in place of this one? My concern is that this one only allows "water" or "water and heating" -- not independent control of water and heating as most do, even though the wiring looks like it treats them separately. Can all systems support independent control of water and heating, or do I need to check? If I need to check, what do I need to check please?
Normally I'd just try it and find out -- but I can't because there's no power, and I need to make the decision before getting the plastering done, only after which the power can be reconnected.
Thanks!
