I have had my Vaillant Ecotec Plus system boiler installed along with VR 65 control center and VRC360 receiver and wireless stat. The sparky did not turn up so this is currently not working...so the plumber and I had a go (both novices!). I have followed the wiring diagram supplied by Vaillant but there are some gaps:
1. the diagram only specifies only Earth, Blue and Brown for the two-port valves so do I just not connect the Grey and Orange
2. The cyclinder (Honeywell) has connections as follows, with the 2 (Block 1) connected to the C (Block 2):
Block 1 Block 2
C Earth 2 C Earth 2 1
The VR65 diagram has only two wires specified so where do they go (the wiring diagram for the stat is based on using a Honeywell wiring centre so is completely different).
3. The Vaillant boiler includes a connection cable between terminals 3 and 4 and states that this should be removed for connection to external controls but does not state if this relates to VR65 or not....I presume they are left alone.
I appreciate I should just wait for the professionals but I am now obsessed with this and want to understand...please help!!
