I'd appreciate some advice with wiring for a Drayton Wiser Heat Hub.
I have a Vaillant ecoTec 837 combination boiler, currently controller by a Honeywell programmer in the hallway. On removing the Honeywell controller, it appears it's connected to the boiler with only 2 wires (a permanent live and a switched live).
I believe I will therefore need to provide a separate 230v supply to the Wiser Heat Hub. I have an existing 3A fused spur ajacent which I plan to use for this purpose.
I'm confused with the wiring requirements on the new Wiser backplate. I have purchased the 2 channel version of Wiser (which includes HW control, which I don't currently need). So I need to use the 2-channel Heat Hub as a single channel unit, simply to control the Vaillant combi for heating only.
I will have 4 wires available at the backplate (live+ switched live to the boiler), plus L and N from the new 240v supply. I'd be grateful for some guidance as to how to wire this, the Drayton wiring diagrams don't cover my particular scenario in using the 2 channel unit for 1 channel operation!
Many thanks in advance
