HELP I AM A FAILURE!!! Switchmaster 9000 Heating control

[duncangunstone]

I need to update my central heating/DHW controller (Switchmaster 9000) and have taken off the cover to check the wiring behind, making sure I buy like-for-like. But, putting the cover of the Switchmaster 9000 back on, the bloody thing doesn't work. I've checked electric feeds and everything else in the system seems to be on and ready to work -- but the controller does not!

Help, it's freezing!

hi it looks like you will have to put in a couple of tempary links with all the power off and the fuse removed, take a feed from the live in and put into the hw out screw and the heating out screw then at least you can tturn it on and off with the fused spur b if you look at the wiring diagram normally a small label on the back it will tell you what numbers are heating on and water on
