How to wire extension kit to simply turn the mains power to the boiler on or off.
I have a very old oil boiler which only has a simple power supply to the boiler and a stat on the boiler itself to control the temperature of the boiler itself.
Their are NO room stats or and other control equipment. If it's cold I turn power to the boiler on and adjust the stat depending how hot I want the water in the boiler / radiators to be.
So I plan to cut the mains cable to the boiler and wire through an extension kit which of course if then wirelessly connected to the Tado smart room stat.
I just need to know what the wiring diagram should be. It should just be simple L+N+E in and Earth common with a switched Live (or Neutral or both) but I am unsure what each of the connectors in the ext box do.
Tado just tell me to remove the old unit and wire accordingly but I don't have an old unit.
Any help would be much appreciatted.
