Questions & Answers

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).
