Of course, he *could* have got it wrong. The pipes on the right *could* just
go to the F&E tank, and the zone valves *could* be one for CH and one for

The pipes on the right run straight to the cylinder. I also have two
CH zones (upstairs & down) - the valves are for each circuit....

Thanks SS for yout time in describing how, with some wiring, I could
stop the pump running. If I'm honest, I think it is beyond me........!
Think I'll wait until the summer - when I change to boiler..

Many thanks
