Hive Install to replace Danfoss TPOne - B

[Red-DiY]

Thanks for the photos.

Two things to note, first the grey wire is already connected to neutral - a little bit poor, considering it is just hanging out loose, in the backbox of your existing stat.
Secondly, one of the brown zone valve wires has been trapped by the lid of the wiring centre - it shouldn't be an issue, but just make sure its clear of the lid before replacing it.

Next, it depends on what you want to acheive.

If you are happy with your single channel Hive receiver replacing the existing stat...

With the power safely isolated,

Connect the Brown wire to the L terminal of the Hive receiver backplate.
Connect the Grey wire to N.
Connect the Black wire to terminal 3
Put the Green/Yellow earth wire into Hives earth terminal.
Then add a short link wire between L and terminal 1.

Alternatively, for a neater finish, if you would like to put the Hive Receivers near to the wiring centre, we can guide you through the rewiring and decommissioning of your existing stats.

Thanks I will try this tomorrow and give an update

Hi All
Thanks to Random's suggestion the wiring for Replacing the existing Danfoss TPOne-B with a single channel Receiver has WORKED great.
Again Thanks to Random and Eric.
Hence I have replaced the Upstairs zone with the Hive Mini Single Channel and paired with Hive Thermostat. All good

Before I replace the downstairs TPOne-B I have a another question.
In our previous house we had Conventional Boiler with a Hot Water Tank. The Hive Receiver and Thermostat we used was the SLT3.
Can I use this Receiver with a Combi Boiler in our new House without wiring up the Hot Water channel part? If so what would be the wiring in relation to what I have at the moment with the TPOne-B
Thanks for your help.

Yes, connect the Brown wire to the L terminal of the Hive receiver backplate.
Connect the Grey wire to N.
Connect the Black wire to terminal 4
Put the Green/Yellow earth wire into Hives earth terminal.

...and give it a go!
