Hi everyone
My father in law is having new Honeywell S Plan Controls fitted as the current ones are old/not working correctly.
I'm starting fresh with it all from the wiring centre. The only thing which has thrown me is the boiler has an interal pump as well as the standard pump upstairs in the cylinder cupboard. Do these both both need to be connected as with the S Plan diagram or do they both get wired directly into the boiler?
At the moment they are both wired into the boiler direct. I'm not sure if this is right or not as he thinks it's never been connected right since day one. The boiler is a Main HE 18.
According to an S Plan wiring diagram the non boiler pump connects in with the orange from the zone valves.
Thanks in advance.
