Hi I’m looking to install the above. Atm I have an older one fitted (old wireless thermostat and old receiver that’s wired into my combi boiler. Pic below shows how my current one is wired, live neutral and would the 2x black wires be switch wires and would matter what way they were wired in? My question is when I fit the new hive receiver can I leave existing wiring as is in my boiler and just connect the new receiver to other end of the cable?
Thanks
Thanks
