What would be the best way to run a L, N and E to the Nest Heat Link if the boiler is currently on a plug?
Would I also just connect the 2 wires currently going to the thermostat to the heat link terminals 2 and 3?
Thanks
Looking for some advice for what will be the most straightforward to install out of Nest 3rd gen or hive single channel thermostat to my Glow-worm 38cxi combi boiler, which is currently wired to a Honeywell t40 thermostat and has a dial programmer fitted.
See photos of current setup and manual...
