Hi, looking for some information.
I have what is probably a fairly standard set-up for central heating and gravity fed hot water with what I think is a Y-Plan design. What I want to know is if it is possible to control the hot water and heating separately?
At the moment if we turn the heating on via the ST9400C controller it also turns the hot water on. We can just switch the hot water on it's own but cannot switch the heating on on it's own. Is there a relatively simple way to change this or is it just not possible?
The system appears to be using a Honeywell V4073A1039 3 position valve and looking around on the internet it kind of implies that it should be possible to use this valve in a way that makes the above achievable or is that just wishful thinking on my part?
