While moving my Hive single channel receiver one wire has come loose and I dont know where to re - attach it. See pictures. Black cable is from the 2 port valve (detach pro) and the white cable is from the Baxi combi boiler 830. Central heating not working though hot water is fine.
Does the blue wire need to be connected to Neutral on the receiver?
Any advice gratefully received.
Thanks

Yes Blue is a Neutral for the 2 port. I think your orange and grey are opposite, but doesn’t matter.

Usually as follows:

Grey - permanent live
Orange - switched live
Green/yellow - Earth/cpc
Blue - motor Neutral
Brown - motor live
 
The whole thing looks wrong, not just that loose wire. Should be...

Blue to N
Grey to L
L linked across to 1
Brown to 3
Orange to boiler switched Live, not directly connected to Hive
Earth to earth

Thanks you very much CBW, I connected the loose blue wire to neutral and the central heating is back on. Very grateful.

Thank you very much muggles for the very helpful advice. I reconnected the blue wire to the neutral and it is working. I am not confident of correcting the other wrong connections as you mentioned, but will get a qualified person in at some point.
Many thanks for your help.
Guisep.
 
Won`t go off topic but I got Hive system with 2 zone and 2 motorised valve. I would like to heat the full house with single thermostat. can I connect both valve into 1 zone controller?
 
It's a bit of a backward step, and if the reason you have two zones is because your house was built fairly recently then it's a building regulations energy saving requirement requirement that was built like that and shouldn't be changed.

If that's not the case, then yes it can be done. The Hive will control one zone and the the controls for the second zone could be removed and the second zone valve wired to the first zone valve so that they both open together.

Ideally, though get two Hive's one for each zone.

Building regulation for this does not really work and save no energy. Actually is made the way you have boiler working more frequently as on those area it kick on different time. For instance having those thermostat in different room is making the heating going in off more frequently than warming the house in a single shot. So the idea is to combine both valve, use a single thermostat and when goes below the desired temperature will warm the full house.
 
I don't make the regs but I think the idea is that you heat the living areas as you need them all day if you are at home, but save energy by only heating the sleeping areas first thing in the morning and just before bed time.

However, it is physically possible to do what you want, but you might consider doing it so that it's reversible just in case you have a problem should you sell or rent out the property and it's picked up when the EPC is done.

Absolutely, I want to have a go but do not make any massive change and leave everything in place and just revert back to 2 controller when I will sell or rent out. Idea was just to disconnect wiring from controller 2 and connect both on controller 1 to open/close valve at same time.
 
You could re-route the live switching wires from both existing room thermostats to the same Hive single channel* receiver [Terminals 1&3]

It doesn't matter which way around the wires go because terminals 1&3 are just an on/off switch. However, you will need to make sure that both of the thermostat 'lives' go to the same terminal, and both of the thermostat 'switched lives' go to the same terminal. If you transpose them, the heating will be permnently 'on'.

*I say single channel Hive as I assume as you have added your post to someone elses that was discussing fitting a Hive to a combi boiler, you have a combi also. If you have a system with a hot water cylinder the wiring will be different.
 
muggles post is over a year old and relates to the original posters question. @Jonny Vee for future reference you can see why the forum rules. stipulate that you should start your own new thread rather than hijack someonelse's.

Apologies, I thought of doing something good and not creating new thread for a quick question.
 
The biggest plus is that a new post is flagged as such, easily spotted and gets maximum exposure and more help. Tagging a new question on to the bottom of an old thread is much less likely to be seen and easily missed.
