horrible for office setting
This is horrible for an office setting if you work at a computer or are required to read/write for extended periods. The lights constantly turn off, requiring you to get up to turn the lights back on.

Third year electrician here. I have yet to be on a job where these switches work without 30+ minutes of troubleshooting or they just don't work at all. I like the legrand brand of products except these

Questions & Answers
Can I disable manual on/off function on this occupancy dsw-301? It's a commercial application and I need it to be infrared/ultrasonic only so customers can't turn the lights off. I will be using 2 of these in a 3-way.
The manual ON/OFF function of the Wattstopper DSW-301 cannot be disabled. This device is a wallbox occupancy sensor switch, and while you can adjust or disable the sensor functionality through settings, the physical pushbutton remains active and cannot be overridden or locked out.
For commercial applications where manual override is not desired, you might want to consider a ceiling or wall-mounted sensor, which would remove user access to manual controls entirely.

If the switch is not working on motions how do you set it to do so
Hi Bobby,
To set this switch to auto on when you enter, you have to put dipswitch 8 in the down/off position to enable auto on.

Replaced sensor switch w/DSW-301. Connected line to blk, grn to ground, capped ylw, and load to combo of blu/wht, red, neutral. Load is 120-wt LED driver. PIR flashes red, device "clicks" on/off, but no power to LED driver. how to diagnose?
Hi Jerome,
I suggest giving the wiring another look. You mentioned the load is connected to a combination of blue with white striped wire, red, and neutral. The wiring should be as follows:
Black > Power from your Service Panel
Red > Load wire to be connected to your fixture
Yellow > Traveller Wire (to be capped if used as a single pole switch)
Green > Ground
Blue with White Stripe > Connect to the Neutral (If there is no neutral present, connect along with the ground wire)
I would verify functionality at this point.

Does holding the button down for 10 seconds return this to operation as a regular light switch that ONLY works with manual button press? NO motion/light control or auto-off?
No, to put the switch/sensor into Service Mode (where it will function like a manual switch), simply turn the Ultrasonic Sensitivity trimpot to Minimum.

DSW-301, instructions don’t show a wiring diagram with a three way switch, will it not work that way or do have to have 2 -301 devices?
Hello,
The DSW-301 supports multi-way wiring, which requires multiple DSW-301 ( up to 4 sensors) to complete a 3-way configuration.
Best Regards,
Justin
