Hi,I have bought this receiver but I am having some difficulty matching up the wiring.The live and neutral are fine but I have an extra wire that I don't know what to do with. ( extra neutral ) I have attached some photos. Hopefully someone can help me. Thanks. Nomad

Are you trying to wire the receiver to where the old thermostat is? Reciever needs a permanent live so unless that old thermostat is connected directly to the boiler. And there is no programmer. You can't do it without a bit of rewiring at the source. You would be better off trying to wire it near the wiring centre or programmer, or boiler. Depending on What type of system you have? Is it a Combi or conventional?

It should be fairly simple. The existing wiring to your current thermostat are likely as follows: [Please check it first by confirming what the existing wires are connected to, or preferably by testing with a multimeter]
Red = Live from existing timeswitch / programmer
Yellow = Switched Live to turn the heating on
Blue = Neutral
If this corresponds to your installation, then the wires would be connected to the Salus as follows:
L = Red wire, plus a link to the Com terminal
N = Blue wire
Com = Link to L terminal
NO = Yellow wire
If you have an existing programmer / timer controlling the heating, this will then need to be set to be permanently 'on' because the Salus will now take control of the heating temperature and timing functions.

We know what you are trying to replace.
But you have not told us about any timeclock or programmer.
If you have one then the usual wiring does not send a constant mains supply to the thermostat.
On the other hand if you really have no timeclock at all then you could.
But what not put it at the boiler location anyway?

These units are becoming quite common, and I have come across two instances where a neighbours thermostat has caused interference, so you may want to consider changing the RF address code of yours from the factory set code, to one selected by you.
