Energy Minder wiring help please

happyhero

Hi I am doing a bit of work for a family and the guy has given me this thing called an Energy minder+. It has a switch on it that can be set to Active or Bypass and 2 sensors and one flex with an earth connections and cables coloured brown, black, blue and grey. I have googled it and found some information but it is a little sketchy, can anyone help me. All the owner says is they sent this to him with no instructions or paperwork and told him it would save him money.

From what I looked up, it is mounted by the boiler with one sensor on the flow and one on the return but I could do with some help with the electrical cable with so many colours. I am assuming brown and blue and earth are obvious ie the current colours but where do you wire it to as one bit I read mentioned the wiring box and another mentioned the stat, so some guidance would be great if anyone knows how to connect it.

Any help appreciated.

The likely place to locate the Energy Minder is local to the boiler as you will have easy access to the flow and return pipes.

The PDF diagram shown in the above is very simple. All the wiring connections required will be available in the boiler.
You only have a mains supply (LNE) and Black/Grey wires to place in series with the time clock or external thermostat.

If you are unsure consult an electrician.
