no just a plea for help

It's all in the valves microswitches.

make it fully pumped

 

[SimonG]

Read twice, answer once.

As Desrob said, fully pumped, so another valve on the hot water.

Add a 28mm zone valve onto the gravity hot water and wire it as a C plan plus adding two zone valves for heating. As long as the orange switched wires on the heating valves are commoned you can have separate time switches etc. Think of it as though the brown wire connects to the switch live from your underfloor circuit.
