I have just installed a Worcester Bosche 24RI. I understand wiring but am lost with the plan I have.In the airing cupboard I have a back box with a bank of 9 electrical connectors. Ther are no markings or signs as to what is doing what. I have a cable from the Pump, the three port valve, the boiler (5core) the control unit (5Core) and room stat and of course power. I would be grateful for a simple diagram as to which cable is in each connector starting from the left numbered 1,2, etc. and colour coded Grateful for assistance.
