Please can someone help me out with this one.
I have a boiler, cylinder, 3nr 2 port valves a thermostat/programmer and UFH downstairs'.
I understand the basics of the S- Plan heating controls as below;
Boiler, 2 port valves and thermostat/programmer (nest) are all connected to the wiring system.
Stat/programmer calls for hot water or heating to rads, this triggers the boiler to start heating and the associated valve to open to allow hot water to the cylinder or to the rads.
UFH has a separate control centre, which I understand works as below;
Stat calls for heat, control centre triggers the boiler and UFH valve to send hot water to the manifold to heat the zone calling for it.
Assuming the above is correct what I cant understand is do these operate as 2 separate control systems, each with a link back to the boiler with 2 valves on the heating (Hot water and rads) and 1 valve on the UFH, or are they somehow linked?
