Questions & Answers

What does each button do? We want to set the room to bright for a learning event.

Asked by: Betsey Iko
The LMSW-105 is customizable so it depends on how your switch was programmed. If the programming was not changed, and the switch is at factory settings, it is a scene switch. The long button is a dimmer that will take the assigned light from 0-100%. Scene 1 (button 1) is 100%, scene 2 (button 2) is 75%, scene 3 (button 3) is 50% and scene 4 (button 4) is 25%. If it is not operating this way, you will need to contact the person who programmed your site for assistance.

Where is the full operational details? I only have the quick start guide.

Asked by: Cory
The LMSW-105 is a part of the Wattstopper Digital Lighting Management System. It has to be connected to other DLM devices to work properly. The manual for the switch can be found on the website. You may also want to look at the information for the LMCT-100-2 Commissioning tool for further programming information.

How does Legrand recommend cleaning these switches to comply with CDC recommended cleaning of High Touch Surfaces? Is there a recommended cleaner or method which can ensure the surface is sanitary without damaging the electronics?

Asked by: Anonymous
Do not apply cleaning solvent directly onto unit. Apply cleaning solvent onto a cloth, then wipe the unit to clean it.

Hello, May I know the maximum wattage allowed on this dimmer?. That is, if I have an LED light fixture which is 24W (wattage of the light), how many number of maximum lights can I install on this dimmer?. Please and kindly advise.

Asked by: Sai Konda
The LMSW-105 communicates with a Room Controller (e.g., LMRC-211, LMRC-212, etc.) which actually powers the load. The LMRC-200 series Room Controllers are rated for 16A for LED loads.

I have this light switch in my classroom and the motion sensor does not pick up our movement well enough, so the lights regularly turn off. How do I adjust the switch so that the lights either always stay on or so I have longer intervals of lights on?

Asked by: Barbara
The adjustment would not be made at the switch, the adjustment would be made at the sensor. Please contact Technical Support @ 800-879-8585 for instructions on making sensitivity and time adjustments.
