Hive heating again. Plumber removed wiring for thermostat!!

[vinny1979]

Evening gents.

I did post a few months ago and successfully fitted my hive, removed old thermostat, left wiring in situ in a junction box and bridged it. All worked marvellous.

Just had a replacement heat only boiler fitted so like for like. I mentioned I had bridged the thermostat wiring so didn’t need to touch it.

Came home and he’s snipped it at the old thermostat end and hidden it in the ceiling, and then disconnected it at the wiring centre.

I’ve just got back from a weekend in Paris and have no heating (not that I need it but)

Problem is I don’t know where he’s removed the wires from to bridge it out!

Apologies as this is a little poor. Was/ is a Honeywell set up

Hive clicks on and off as should.

Hot water works as boiler doesn’t control it.

You can see the taped off wiring at the bottom from my old thermostat

Can’t you just bridge it inside the junction box?

 

[vinny1979]

He’s took that away.

Snipped the wiring and buried it in the ceiling, then at this end (heating control centre) he’s disconnected and taped off the wiring

Thank you

 

[Mottie]

Connect it up again.

 

[vinny1979]

I would but my point is at the other end (my picture) he has also disconnected the wiring and I have no clue where it all went

Both ends are disconnected

It doesn't matter where it went if it’s disconnected. Just connect up in the connection box. Either that or get him back to do it correctly.

Sorry I haven’t made my point clear

My boiler isn’t getting the call for heat now.

Because I bridged the wires at the old thermostat

He’s removed everything as pictured including my bridge, and disconnected the 3 wires from the heating centre, to which terminals I have no clue.

If I did I would bridge the two necessary, the live and switched live

Sorry I haven’t made my point clear

Don't worry, I thought your point was clear enough - if you knew where to connect back up the old wires, we wouldn't be having this conversation!

Just had a replacement heat only boiler fitted

What heat only boiler do you have?
Does it have a switched live connection for the pump fed from the boiler?

And I believe the top right hand five core flex connects to the Hive?
If so, can you give us a pic of the wires behind the Hive, just to confirm?

 

[vinny1979]

I haven’t touched the wiring for hive as was direct replacement when I first did it.

In terms of the boiler having a feed silly question but how do I know?

There is a twin and earth to an isolator next to it? Always has been.

Thank you

 

[vinny1979]

Appreciate replies

I can of course get more photographs tomorrow and show where each wire goes as all in airing cuoboard

Thank you

Also I believe it’s a grundfoss pump, black with a led light and a button with 4 modes

I believe the wiring centre has been linked out correctly, with the green/yellow (oversleeved brown) - C/H On from Hive in terminal 9, linked to the Brown/White wire of the 3 Port Valve, in terminal 3.

This is how I think your cables are laid out...

I would first check the terminals are tight, and if that doesn't work, try connecting the brown/white directly to the green/yellow (oversleeved brown), in a spare terminal.

After that, the problem is likely to be elsewhere...

 

[vinny1979]

Wow. That’s super helpful

After work tomorrow I will cross check this against what I have

Thank you again

Your plumber should have sorted it and or tested it. I would ask that it be sorted or deduct from the price for you having to sort it. Daft question, but have you took the call temperature higher than the room temperature with it being hot?

The heating isn’t set to 'off' on the hive room stat, is it?
