Hi. I would like some advice on swapping receivers. I currently have a Heatmiser Neo wireless setup but have recently purchased a Hive active heating single channel stat pack as I am after the app functionality. I would like to swap out receivers and assume it is a straight swap looking at the installation instructions but I don’t understand why there are 2 wires going to neutral (photo supplied). One is from the fused switch above and one is from the boiler (Vaillant ecoFit) but all installation instructions online show only one neutral going to the Hive receiver. Can I or should I use both still? Any help much appreciated.
