TRY THESE PEOPLE SHUAN www.[B]tglynes[/B].co.uk NOT SURE IF THEYLL DO MAIL ORDER BUT MAY POINT YOU IN THE RIGHT DIRECTION THEY HAVE AN ELECTRICAL SIDE AND DO ALL THE MAJOR BOILER HOUSE STUFF

Is it a PCB or part of one, if it is you will probably have to go to the engineer who made/designed it,
what does it control,
You have hit my curiosity button

How does it work? Is it similar to a weather compensator?

Thanks

thanks for all your help guys. went to nobbs and jones office in preston today, ( impressive and very helpfull teckies )
ive learnt the gadget i require ( is only an automatic switchover between boilers 1 & 2 ) is no longer made, the panel is 18 years old, electro controls used to make the parts.
anyway, an entire new control panel to be made, and installed.

about 5 grand by my reckoning.

what happened to the good old days with an on/off switch??

bob, shall satisfy your curiosity with a couple of photos in a couple of days when i get back to that site!

cheers everyone
