Evening.
Is there any way of wiring a Sundial ST9420C programmer into a gravity fed hot water/pumped heating system with no motorised valves? I know the best thing to do would be to put a 2 port valve in and turn it into a C-Plan, but I would like to know if it is possible without.
Thanks for any thoughts.
