Wiring Question RE Adding Wireless Stat To Gravity HW System

I have a Concord WRS boiler, with gravity HW, pumped heating. It has a Potterton EP3002 programmer

I want to add a Danfoss RET-B-RF wireless room stat

The old stat was in the hall, but the previous owner connected the wires together, and plastered over them.

Can I wire the receiver directly into the programmer, inc the receivers L and N? If yes, which wires connect to which terminals?

Failing this, I have found a two wire cable that comes from the wiring centre which I believe runs to the old stat connection in the hall. There are only 2 wires in there. Do gravity systems only have 2 wires to a stat? The RF receiver needs 3 wires (plus L and N supply). Which 2 terminals in the receiver do I connect the 2 wires to?

Judging by your questions and apparent lack of electrical knowledge I would suggest you employ a suitably qualified professional to undertake the work.

I thought this was a DIY site?

Take a clear picture of the wiring centre and connections and ill tell you where to put ya wires

Cheers! You're a diamond!
