Hi,

I have purchased a new hive system which I want to install into our house, however as our current central heating system does not have a thermostat, I am going to need to wire in the hive receiver from scratch. I have gone through the boiler manual and have found the external accessories wiring and now just need a little advice as to the wiring order.

Attached is a pic of the manual and connector in the boiler that I believe needs to be wired to the hive receiver.

So from reading this forum and other threads relating to hive installs, I believe I should be connecting it in the following way:

RT connects to N
24v connects to L
Bus - connects to 1
Bus + connects to 3

I also remove the red loop wire between RT/24v

Is it that simple or have I got this massively wrong?

Thanks in advance for your help.

Ok so after a bit more searching I have found that I'm way off the mark!

Power needs to come from the mains, so should i take it from the feed in the boiler (pic1) or off the back of the isolater switch on the wall (pic 2)

Once it has power I believe I then need to connect the RT/24v to points 1 and 3 on the hive diagram (does it matter which to which?)?

Is this now correct?

Thanks in advance.

Yes
The Hive needs a 230Vac mains supply to N & L. But your system uses 24v for switching.

Edit. Ah you figured it out yourself whilst I was typing.

Thanks Stem.

Is it best for me to come off the isolator switch for the power?

Also is the order for the switching relevant? Or does it not matter which way round they are wired?

Thanks for your prompt response.

Either will do, I imagine at the boiler terminals will be the easiest

Correct. 'Common' and 'Heating On' are the connections you want. It doesn't matter which way around. Remove the red link between RT/24v.
 
Thanks so much, you are a star!

The wife will be please it will be working by the time she gets home!

Going to go to B&Q and get some wire, any recommendation for what type to get?

Thanks again
 
If you do run the cable into the boiler, then 1mm2 or 0.75mm2 heat resistant cable would be good. This will also be good for the 24v switching wires.

If you get the main supply from the FCU (fused connection unit) then use 1.5mm2 twin and earth. Make sure that you connect it to the 'load' terminals not the 'supply' terminals
 
So twin core heat resistant 75mm2 for both and just run the power from the boiler.

Thanks.
 
You only need heat resistant where the cable enters the boiler. And, it's 0.75mm2 not 75mm2:eek:
