Thank you so much!! Worked a treat! Heating and water back on.

Hi, Our Horstmann channel plus NLH27 HW & CH programmer has given up! Bought a Danfoss FP720 V2. Attached is pic of the actual wiring from the NLH27 which doesn’t correspond to the NLH27 wiring diagram. So am struggling to wire up the FP720. Any advice?
