    The documentation says you must have a load per gang for the switch to work,
    whats the effects it you dont - does it not function at all ??
    Does this mean if i install a 2 gang and only one light say that some sort of dummy load has to be put on the second switch ??

    The simplest rule is to do what the instructions say.

    If you want only a single channel of load control, install a 1 channel unit.

    Dimmers and relays are slightly different in how they operate and extract power through the load.

    In the case of the relay products, use of only a single channel on a 2 channel device will cause a very strange and nasty thing to happen (you have been warned).

    Don't put dummy loads on - then you have to find somewhere for the load to go, and the idea of a load hiding in a wall dissipating (power / heat) or being switched by accident is not attractive, and possibly even dangerous.

    I assume that what you really mean when you say "a load per gang" is actually "a load per channel". So you're asking if you need to have both channels of a 2-channel C-Bus Wireless device connected to something? The term "gang" applies to the number of buttons and basically unrelated to the number of channels.

    Yes, this is true. It also means that if the load on channel 2 blows then you might not be able to control the load on channel 1 either.

    It's a trade-off situation. The entire design is 2-wire so that it can be retro-fitted where no neutral is available. The consequence for 2 channel units is that you need 2 loads to keep them happy.

    G'day Dave,
    Because of retro fitting, we obviously just use the existing cabling, meaning there is no neutral at the wall plate. So your light (fillament) is the path to complete the circuit. Therefore a blown globe and / or no load on second channel means an incomplete circuit and no joy......

    Cheers,

    loads

    It just means i can not put in switchs with spare outputs for later use, going to have to match current loads and if additional loads required change switch to bigger one.

    Yes, but this will be the least of your worries. You will have to get the new wires down the wall for a start (unless you have had the foresight to install conduit or extra wires).
    If you install a switch with extra keys, you can always use it to control a separate wireless dimmer which can be wired in anywhere.
