Wiring boiler thermostat receiver

[anthonyseoul1]

Hello all,

I need some help wiring a Siemens RDJ100RF Thermostat receiver.

A house I just bought has a brand new boiler but the boiler is just plugged in and has no thermostat. I'm trying to figure out the wiring and have searched on the internet but I'm still unsure of exactly how to wire this up.

I have mounted a fused spur next to the boiler and the boiler has some pre-wired flex coming from it. Could someone guide me as to how to wire this?

I have attached pictures of the boiler, the boiler connections and the thermostat receiver connections.

Thank you

Removal of the cover on that particular boiler involves the combustion circuit, so needs to be checked for safety afterwards. Piggyback (using 5 core) the L and N at boiler to receiver, and take the link out and run the 2 switch wires from that linked part to Lx and L1.

Thanks Chris.

So the flex to the mains in terminals in the boiler should be coming directly from the fused spur?

Ideally yes.
