Hive thermostat installation

[Red316]

Hi, I've just changed from a EPH thermostat system to Hive, just wondering if anyone could help in matching the wires up for me, are they installed correctly?

I've attached 2 photos showing the change I've done between them, thanks

You're close, but not quite there.

For safety's sake, you need to strip more insulation (outer sheath) from the black cable.
The end of the green/yellow wire is almost definitely earthed. That is mere millimetres away from the live terminal and a big bang.
Strip more insulation from the cable and terminate the green/yellow wire properly in the Hives earth terminal.

And with a single channel Hive, common is on terminal 1 and C/H on is on terminal 3.

Additionally, the wiring could be a little tidier - there are a couple of strands of wire that haven't been captured from the blue wire, and some insulation has been trapped under the terminal on the brown wire.

Great I'll get the earth terminated properly, unfortunately the controls don't seem to be switching the heating on/off like it should, same with the app, hopefully these wires are in the right place, thanks

Have you moved the wires to..

Definitely on the correct setting on the boiler if applicable?

Hi I've changed these wires around now yes, attached is the setup I now have, hopefully these are the correct settings for the Hive and will check now to see if the thermostat will now control it properly

These connections are for a Biasi boiler, do the wires look in the right place?

That's a lot better, well done.
If your previous thermostat controlled the boiler with that wiring, there shouldn't be a need to change the settings.

Although your water pressure is in the red. A little top-up is required.

I can't seem to be able to turn the boiler off by the app/thermostat. It'll only turn on then stay on, what would the problem be?

Sounds more app related. Does it turn off without the app?

What colour is the LED on the receiver?

If the batteries are out of the thermostat, does the button on the receiver turn the heating on and off?

...and how long have you left it running after the thermostat turns off?

Only if i turn the boiler off itself, doesnt with the thermostat either

It's a solid green block LED so appears to be paired up

If the batteries are out of the thermostat it's still powered up.

The receiver lights can bu turned on/off, but the boiler doesn't turn off and stays on, regardless of whether its turned on or off on both the receiver and app

So, how long have you left it running to determine it's not turning off?
