Replace Wunda UFH receiver with Hive single-channel receiver

[bobazanetti]

Hi all

Just wondering if it's possible to replace a wunda receiver and thermostat with a single channel Hive receiver? The Wunda receiver is rubbish and needs basic batteries, ie not Duracell, to work.

I have attached an image of the current Wunda receiver.

Any instructions out there on how to wire this up? I can't imagine it's that difficult.

I’m confused, that current receiver looks like it’s mains powered?

Hive should be L to L, N to N, and L1 to Heating on, and link L to Com. Also sleeve the green/yellow as brown, otherwise it could be mistaken as a cpc/earth wire.

Thanks for that. Have drawn diagram to see if this is correct (and for anyone else looking). Obviously the green/yellow is live, so will mark.

Yes, that should work.

Doesn't seem to be working. I haven't hooked up to the app or hub etc, but it should show a light looking for something, right? Feels like no power is getting through at all.

Ah, my bad. Took off the cover and a wire had come loose. S'all good now, works a treat. Just need to sync it to my app. Thanks CBW
