Questions & Answers

I'm working with an LMSW-104 switch. I would like the top (first) button to turn on the lights to 100%, the second button to turn on the lights to 50%, the third button to dim up and the fourth button to dim down. Is this achievable?

Asked by: Andrew
Yes it is. You would configure the 1st and 2nd buttons as Scene Buttons, the 3rd button as ON only, and the 4th button as OFF only, per the Button Configuration instructions in the LMCT-100-2 User Guide. The User Guide can be found here: https://www.legrand.us/lighting-controls-and-systems/software-and-configuration-tools/digital-lighting-management/digital-wireless-configuration-tool-w-usb/p/lmct-100-2?text=LMCT-100-2

The data sheet indicates that a two button (or any switch with moret than one button) can be used to dim the load. How do you set the buttons for dimming?

Asked by: Joe
Hello Joe, This can be accomplished via our LMCT-100-2(programming Infrared remote). We will need to configure the switch buttons to be an ON-only/Off-only to allow dimming control/function.
