Wire Hive thermostat V2 to Vokera Excel - I 25c

[Andrea_304]

Hello everyone,

Trying to work out how to wire the Hive thermostat to my Vokera boiler but can't get it to work.

Just testing the setup out so currently wired the receiver to a plug.
I've removed the existing link that was in place on the two TA terminals on the X11 terminal as per diagram and connected to terminal 1 and 3 on the hive.

When pushing the button on the receiver nothing happens. Does anyone have any advice ?

Thanks in advance.

Silly question, do you definitely have a single channel Hive?

I'm afraid I can't find the specific manual for that model online, but have you set the heating control on the boiler to continuously on?

As the boiler appears to support OpenTherm, you may want to look into the benefits of having an OT thermostat over the on/off switching Hive, before making it a permanent installation!

If this doesn't get you anywhere, @vulcancontinental will have the answer

Can’t see anything that states X11, but could have wrong manual. Can you post photo of wiring at the boiler end? and as above, confirm which version of Hive.

Yup, I found that manual and it's the wrong version.

The OP originally included a photo from the Excel-i 25C manual that showed the X11 and OT terminals.
The photos have since disappeared!
