I'm hoping to retrofit 2 x 22mm motorised valves into the outlet side of my boiler pipework to create 2 separate heating zones. As it stands the boiler outlet Tees off in 2 directions, upstairs and downstairs.
My hope is that during the night I can have upstairs Rads on and downstairs off, during the day vice-versa.
Fitting the valves locally to the boiler won't be an issue. My confusion lies with how best to program these valves. For simplicity I was thinking about controlling these zones timewise and not temp related (I'd let TRV's cover that requirement). That would also negate the need to run cables to wall mounted Thermostats.
Are simple timer controllers available that I can retrofit in the proximity of the boiler and motorised valves ? If so can someone please give me a few examples.
