Hi all,
this is my first post, so please go easy on me...
I'm trying to understand how my central heating system is wired - I'm nearly there, but I need to see a wiring diagram for my Switchmaster mid-position valve.
I've found that most valves of this type have 4 wires plus an earth - this one has 5 wires plus an earth.
Any help would be appreciated,
Thanks, Mike.
