I am trying to replace the ESI ESRTP 5 Programmable with Hive receiver at the same location (using the existing wire)
This is the current wiring (ESI Thermostat) Brown- Live (1) Blue-Grey- Neutral(2) Black- Brown N/O (5)
I have attached
However; it's not turning the heating on. After reading all the conversation in here , I assume I have to create a link from L to Common Is that correct If not what I am missing please
