    Hi,

    I have a few lightwaverf devices but this is the first I want to use to control an appliance. I have a 600w heater that is currently cabled into a switched fused spur, I want to use the 3000w relay between the fused switch and the appliance to allow control. What I don’t understand though is what I should do with the relay, it seems wrong to have it hidden and just dangling in the drywall void, plus I’ll need access to then pair it anyway.

    So, do I instead cable everything in but have the relay essentially on the plasterboard wall by the socket with the cables coming through the wall from the switch, again this seems odd as then they’ll be exposed cables!?

    Am I missing something or is this simply the wrong piece of kit for the job?

    Thanks

    As you say, I wouldn’t put it behind the plasterboard.

    Perhaps a suitable solution would be to put a double pattress box in/on the wall next to the switched spur, put the relay in that, and then cover with a blanking plate?

      Update, item is too large for a double pattress box, any other ideas!?

      Hmm… what dimension is too big? I have an LW830 which is surface mounted in my airing cupboard to control the immersion heater. I’ve not tried, but I can’t see why it wouldn’t fit in a surface or flush mounted pattress box that’s 143mm x 83mm x 47mm, like the one I linked to. LightwaveRF specs say dimensions of relay are 135mm x 65mm x 37mm.

        The pattress box dimensions do no account for the internals so the clips where the screws go, tried everyway round but not even if I removed the screw tabs off the relay would it fit!
