    Hi guys,

    I haven't used the bus coupler before so have a quick question. I plan on using some iconic rocker switches to switch the contacts on a bus coupler for a bathroom setup. My question is can you have two separate channels of the bus coupler switching the same output. For example, a bathroom fan will be switched like a 2 way set up on both entrances into the bathroom... if one switch is already made and the fan is running will the other switch, when switched be able to turn it off and vice versa?

    A bus coupler is just a normal Cbus switch without the physical switch. If you hook it up to a rocker switch it will generate a short press followed by a long press when the switch is turned on, and a long release when the switch is turned off (unless you flick it very quickly which is unlikely). If you set the macro function to ON/OFF then it will turn the group ON when the switch is turned on, and set the group OFF when the switch is turned off.

    If you have 2 bus couplers assigned to the same ga, either will control the ga, but not like a normal 2 way. If both switches are off and you turn one on, the ga will be turned ON. To turn it off from the other ga you would need to turn the other switch on and then off again to generate the off message. To turn it back on from the other switch (which is still on, you would need to turn that switch off and back on again.

    Whether that is ok is up to you.

    To make it act like normal 2 way hard wired switches you would need a logic device and a bit of programming.

    Generally bus couplers are used with momentary push button switches.

    Sorry NWB, am I mis-understanding some other additional requirement here pushing you in the bus-coupler direction?

    Instead of using bus couplers and Iconic 240v mechs to link to C-Bus control of the fans, why aren't you just using the C-Bus '40 Mech' Masters (aka an Iconic plate compatible C-Bus switch) in the Iconic plates in your bathroom. The 40 Mech C-Bus switch provides full 2 way control like any C-Bus switch without the rocker switch issues Ashley has highlighted and makes it a standard C-Bus install.

    Brad's solution is how it should be done :)
