Replacing a Honeywell t40 with a Beok tuya.

[Gelu]

Hi!!! I try to look for it but didn’t find anything similar. I want to change the t40 for a beok tuya but only have 2 wires plus the earth conected. How I do it? Thanks.

If you only have 2 wires, then you can’t. You need to run additional cable or change the thermostat

I have three connected, one been earth and 2 with no connection. The black one has a brown sticker around. The blue and the grey are not connected.
Thanks

Ok, so more wires are potentially available. Check the blue wire if it’s connected either in the fcu or wiring center and if not, connect it to a neutral and then the brown to a permanent live (if it’s not already), link L to 4 and then switch live to number 5 and sleeve brown if possible. Connect earth to a connector block.

Ok. What I understand is to check the blue for current if it has current, put it in the N, make a bridge with a bit of cable between L and 4, connect brown to L and black with brown sleeve to 5. And the earth to a conector block.

Thanks

No, I didn’t say check for current, I said check if it’s connected. Everything else is ok.
