Hi
Please can you advise on the wiring for the following set up Vaillant 831 combi controlled via Sunvic TLX RFP (wireless) controlling one heating zone valve and the TLX6501 (wired) controlling another heating zone valve. 3 and 4 on vaillant board is 230v so the link will remain on receiver, all wiring terminates in wiring centre, does the SL from receiver and hard wired stat go to brown on zone valves and the grey and orange from zone valves go back to 3 and 4. Main point is how many wires do I need to take to receiver unit, is it just L,N and one other for the SL. Thanks
