Thanks so much for your patience with me. That has fired straight up!!! A happy home.

amazing!!! I can't believe I missed that. What a fool! I'll give this a go and report back, though I am sure this will do the trick now.

There is nothing much to it as it just plugs in via a Molex and uses the OpenTherm wiring in my boiler. (I wish Hive was OT this would have been so simple) Sorry for the link - but this is the guide to the receiver...

Yes - without the receiver connected nothing works.

Hi - I wondered if you had had a chance to look at the pictures yet? I'm sure I've tried just about every permutation but cant work this out :( all assistance gratefully received!

Picture 1 shows my current wiring, which is working as long as the Ideal wireless receiver remains connected. Picture 2 shows the Ideal wireless receiver Picture 3 shows the back of the wireless receiver - you can see the Molex connector that joins it to the PCB Picture 4 is a close up of the...

Fair enough - I will do this in the morning now when there is a bit more light. I haven't implemented what I have drawn yet but will do so and photograph. Cheers for all your assistance.

So, based on what you have said, this is how I should be wiring the receiver. I'm confused why connection 1 in the receiver would not be used at all. This would leave 1, 2 & 4 in the receiver empty.

I tried this, so removed the wire from 1 and put it in the live connection in the receiver. I removed the boilers own wireless receiver and powered it all back on...I was again unable to get the heating to come on from the Hive thermostat.....its very odd.

Just to confirm, that would be putting the wire that is currently in 1 to the live port?

Possibly? And this would be done inside the receiver? Which port would I bridge with live?

So I have now got this working - but as suggested with the old receiver connected and the thermostat plugged in. I have had to put the old thermostat at maximum and the always-on for it all to work. Annoying that I will have to keep this hanging around and full of batteries...

The problem is, the actual programmer part is built into the thermostat, so I can't just turn it on as the thermostat needs power, and therefore you have to set a temp etc. Does this make sense?

also just attached the relevant pages from the installation book of the boiler...in case that helps.

Thanks. The first picture shows the cables I have connected to the receiver. Second shows the Molex connector that went into the wireless programmer.

Hi understood. So where exactly do I do this? Should I put the wire bridge back in at the boiler end, like in this photo? Or, do I bridge them on the white connector I disconnected from wireless receiver? If the former, obviously this photo does not show the wires connected to 1 & 3. In case...

Hello DIYers I made a similar post a few days ago that didn't get any helpful information back. I though I would update where I have got to, rather than continue on with that one. I am aware that I should not be removing the cover of the boiler and accept all risks in doing so. That said, the...

Hi I am just after some quick advice. I am removing a Nest thermostat and replacing it with a Hive one. The Nest is using OpenTherm which I know the Hive doesn't use. My current wiring can be viewed here In picture 2 you can see the OT connection - I am just going to remove this. In picture...
