S Plan, 2 Houses, 2 Pumps, 2 Programmable Controllers, 1 Shared Gas Boiler

[jimmycooker]

Is this possible?

Do you just wire up the boiler as per the S-Plan Wiring Diagram, and wire the boiler switched live from both controllers?

Do i need a bypass valve? How is this controlled....don't the boiler pumps stop when the valves close?

Thanks,
James.

It is possible and quite easily done but why would you want to do this?

2 seperate HW cyls?
4 motorised valves?

You probably won't need the 2 pumps

Wire as a Std S plan with another programmer, cyl and room stat switching the other pair of valves.

You will still need a bypass
