Wiring diagram for Central heating system

[stevecarr]

Can anybody direct me to a website that shows the wiring diagram for a pumped central heating system, I need to know how?
1 pump
2 boiler
3 room thermostat
3 cylinder thermostat
4 3 port valve (Honeywell)
5 programmers (Drayton tempus7)
Are wired together in the connector blocks.
Problems started when I installed a new tempus7 programmer, whenever I wanted hot water only, I would get hot water but the central heating would also come on, if I wanted central heating only, nothing at all would work.

So I’m thinking the 3 port valve is stuck in the open position, because the little lever on top of the valve is very floppy when I move it, So now I have a new 3 port mid-position valve, but before I install it, I would like the wiring diagram for my system, just to make sure the wiring is correct
thanks
