Reviews

Rated 1 out of 5 by from 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.

Questions & Answers

I have 3 x 301's in a row. please post a wiring diagram for more than 2 devices in a row. Also when should use the walk thru mode ?

Asked by: dale
We do not have a diagram that shows more than 2 sensors. You should connect the primary switch, install the second per the diagram and then mirror the same with the remaining 2 switches. A short hallway that is not used often or a storage closet application are places where Walk through mode may be appropriate.

Can this be use on one side of a 3 way system with the other switch a regular 3 way>

Asked by: cody
Hello Cody, The DSW301 Occupancy sensor supports Multi-way functionality for use with additional DSW301 sensors. The DSW301 will not work with a traditional 3-way switch and must be paired with another DSW301 for 3-way applications. Best Regards, Technical Support

Is the watt stopper dsw 301w  also a 3-way switch

Asked by: Anonymous
Hello, DSW-301-W supports the following Multi-way features: (Total of 4 Sensors) The Multi-Way capability is available on all models. Sensors can easily be wired together for convenient control of a common load. When wiring this way, only use 300 series sensors. Multi-Way in 300 series is not compatible with prior sensor models. The following principles apply for Multi-Way: • All units should be on the same phase. • All units can see each other’s push-button events and respond accordingly. • All units can see each other’s PIR trigger event. The response will be determined by the Light Level setting and/or conditions of the space of the detecting sensor. • The time delay for all units is defined by the unit with the smallest time delay Best Regards, Technical Support

Is there any way to purchase a replacement plastic lens for this? During construction, mine popped off and was swept up and disappeared, and it seems like such a cheap little piece that should be replaceable as it is easy to remove and/or damage.

Asked by: Mea Felton
The lens is not available as an individual part. Please contact Wattstopper Technical Support for further information. 800-879-8585.

What relay positions are needed to return this until back to basic on/off (no motion sensing) functionality?

Asked by: ankr
Reset to Default Use the DIP Switch Settings tables shown below to return features to factory settings. To reset the DSW, press and hold the Relay 1 button for 10 seconds until a triple beep sounds. This resets the sensor and disables light level control (the brightest ambient light will not hold the light OFF).
