There is a standard two core plus earth cable running from the timer/programmer to a double plug socket. The boiler and pump were/are plugged into this socket. The live (red) wire goes to the stat (now the receiver) and returns from the stat/receiver to the double socket where it is connected...
No - you misunderstand me. I will definitely take the advice about not using an earth wire for the neutral connection now that I have figured out which of the connection options was the correct one for my set-up.
I just need to get hold of a length of more suitable cable and the job will be...
All I can tell you is that the old stat (and now the new receiver) was fed from the programmer/timer which was feeding live, neutral and earth to both the boiler and pump. The stat was wired in series into the red live feed. I have attached the live wire to the COM of the receiver and this...
An update! Your advice above turned out to be incorrect. I tried wiring it up the "volt free" way but this didnt work so I reverted to the 230v option and this did work. I used the spare earth wire to connect the N terminal on the receiver to a "common" N at the nearby socket. At first I...
