evening chaps....i have been registered to fit unvented cylinders for a while now and i'm currently on my first install fitting a unistor 260, a ecotec plus 637 and 2 heating zones.
I have asked about wiring this lot up a few weeks back but now have a different question.....as specified by vaillant i will be using the vr61/2 control centre, a vrc 430f control with a vr 81/2 to control the second heating zone.
The question i need answering is....inside the vr 61 there is dedicated slots for the 3 motorised valves....now on the motorised valves there are 5 wires as you know but only 3 ports inside the control centre for the wires....i know that the 3 ports are for l,n and e....so what do i do with the other 2 wires for the valves??? are they not needed?? and do i just do away with them?
cheers.
