I have just installed Hive and after some messing around managed to get everything talking to each other. The only problem is the boiler will not fire, the receiver is showing all green lights showing it is working but the boiler refuses to fire except when there is DHW demand.
On the boiler - a Worcester a Junior 28i Combi - there are only three terminals Ls - live supply, Ns - Neutral supply and Lr - or switched live from the thermostat. On the Hive receiver I have L & N connected to terminals N & L respectively and the switched live connected to terminal 3 - Heating On (NO). Terminals 1&2 must be right as the status lights would not be on so that leaves the switched live which could be wrong. The remaining terminals in the receiver are 1 - common and 2 - Heating off (NC)
Have I got the wiring wrong? Will I do any damage swapping connections round, the guys on the Hive live chat have not been any use referring me back to the wiring diagrams.

(so called) volt free relay contacts, and you need to link the Ls to
the COM to make it work.

From your description, I'm assume that you've got the single channel

(heating only) rather than dual channel (heating + hot water) receiver.
The single channel receiver works in a different way from the dual
channel jobbie.
The L&N are purely to power the receiver. The switch is what is usually
called "voltage free" and can be used to switch anything you like -
including low voltage stuff. It's a changeover switch, in which COM is
connected to NC in the off position and to NO when on. So the boiler
won't see anything from NO unless you supply power to COM.
So all you need to do is provide a link from L to COM, and all will be well.

Thanks Graham and Roger, I had just come that conclusion myself and was about to post an update. I rewired my original programmable thermostat back and everything was hunky dory. It gave me an opportunity to spot a small circuit diagram on the back of the receiver and you are right terminal 1 is the common for a changeover switch between terminals 2 & 3 and as such is not wired to anything and will require a link between it and Ls. That's tomorrow's task now.
Thanks again for the quick responses. I have previously wired heating and water programmers using the common backplate and have never had to provide links only L & N and just assumed it was the same. As you say on this L & N only provide power to the electronics. I will confirm the results tomorrow.
The Hive manuals do not have any wiring diagrams neither does the website to which I was referred to by the guys at the live chat service. I get the impression it's all about drumming up custom for BG even though a bit more info would enable anyone with a bit of ability to do the installation.
Thanks again

of each terminal on their receivers, but don't have any overall system
diagrams showing connections to the outside world.
Unlike the heating receiver, the Heating+Water receiver (which I have)
*does* have internal links from L to COM on the 2 relays, and can't be
used for non-mains switching applications. It took me a lot of digging
to sort out what was what before I bought mine.

Yes, the Hive installation manuals are not very good. They show the use

I can confirm that a connection between L and terminal 1 - Common was all that was needed to get things going correctly. Hive is now responding to commands from the app and all that remains is to get to grips with the app and set up some schedules.
Thanks again Graham and Roger, it's a pity BG in their installation manual could not provide the information a simple wiring diagram would have done. It was by chance I spotted the tiny wiring diagram on the back of the receiver and realised the changeover switch was isolated. Even a reference in the install manual pointing out the diagram would have helped, then again if you are trying to drum up some business keeping a few things a bit of a mystery helps.
