Hoping someone can confirm what I’d like to do is correct.
I still have a pump and blending valve for my UFH, from when we had an oil boiler, controlled by a roomstat via a wiring centre.
Yes, I know it would be better without the pumpset but it’s where we are.
I’d like to get rid of said stat and wiring centre, so am I correct in saying that if I wire the UFH circulation pump directly to MA1 in the HPI, this will control the pump, switching it on/off, when there’s a demand for heating/cooling?
My understanding is that MA1 would more usually control a post buffer pump. We don’t have any of that, so MA1 is currently not used for anything.
