So the customer has bought:

A Potterton Gold Combi gas boiler, no tank, so hot water on demand.

A Siemens programmable room stat RDJ10

There is a FCU

Plumber has fixed boiler to wall


So am I being thick and can't figure out the wiring and the customer hasn't allowed space for a wiring centre (or similar)

Yes I realise the boiler needs PL, SL, N and E!

Thanks


(tin hat well and truely on!)

What is it you want to know?

You wont need a wiring centre, just a 5 core flex to the receiver of the wireless stat from the boiler and a 3 core from the fcu to the boiler

Is it an RDJ10 or an RDJ10RF stat Murdoch?

 

[Merl]

RDJ10 stat only requires a 2 core to it from the boiler PL & SL across LX & L1. The internal battery powers the stat unit & internal relay. An RDJ10RF will need a 5 core from the boiler to the receiver unit.

But I bet you knew that already! ;-)

RDJ10 ok.

Its a weak area for me, central heating systems.

Not so weak though that the dead short N-E on the boiler circuit, maintained and installed by a well known large company, I recently put a CU in for (TT, only half of board on an RCD), was probably the one-of-two of the motor for a zone valve motor winding cables that was shoved in with all the cpcs.....

"well it worked didn't it"

" not with an RCD!!!"

we see some terrible, terrible work.

Agreed. ...... No need for a wiring centre.

Combi boiler has no need of an external hot water tank, it heats on demand.
No need for external pump as it is internal to the boiler.

Combi's just need a live supply and a switch live to fire the heating up.
Some have a live supply and then two terminals with a wire link in them, remove the wire link and connect the external controls so that they switch these two terminals to fire the boiler.

As already said, should be just a supply plus cable for the stat (4-core if that model needs a neutral). Make sure it's heat resistant too, unless it enters where the casing never gets hot.

Hello. I have installed a few of these. There are two types though.a hard wired and wireless. The hard wired needs two cores and the wireless 3 cores. have fun.
