WattStopper PW-100-I – Frequently Asked Questions

1) Does the WattStopper PW-100 wall switch occupancy sensor need a neutral wire?
No neutral is required. The PW-100 PIR wall switch sensor wires like a standard switch, which is why it goes into older retrofit boxes where no neutral was pulled. It works on either 120V or 277V, so the same part covers a residential-style branch circuit and a commercial 277V lighting circuit.
2) Does the PW-100 turn the lights on automatically when someone walks in?
Not by default. The PW-100 ships set to Manual-ON: someone presses the switch to turn lights on, and the sensor handles automatic shut-off when the space empties. That is the bigger energy saver and it is what many commercial energy codes expect in offices and private rooms. If you want lights coming on by themselves as people enter, this is not the sensor to spec.
3) Is the PW-100 a PIR sensor or dual technology, and where does that matter?
It is passive infrared only, with high sensitivity and dense coverage. PIR needs line of sight to moving body heat, so it suits open offices, private offices, classrooms, retail floors, and corridors where the sensor can see the occupants. In restrooms with stall partitions or anywhere occupants sit behind obstructions, a PIR-only switch is the wrong choice and you want a dual-technology or ultrasonic sensor instead.
4) Can I use one PW-100 to replace an existing wall switch in an office?
Yes, that is exactly the format. The PW-100 mounts in place of a standard wall switch in the existing single-gang box, so a retrofit is a device swap rather than new rough-in. Because no neutral is needed, you are not pulling additional conductors to make it work. Typical applications are offices, retail, schools, healthcare, hospitality, and multi-family common areas.
5) What colors does the PW-100 occupancy sensor come in?
Two: ivory (PW-100-I) and white (PW-100-W). The lens is color matched to the faceplate and the profile is low, so it blends into a gang of standard decorator devices rather than standing proud of the wall. Match it to the existing wiring devices on the floor so a retrofit does not leave one odd switch in the bank.
6) What operating modes can be set on the PW-100 sensor?
Besides the default Manual-ON behavior, the PW-100 has selectable walk-through, test, and presentation modes. Walk-through drops lights quickly when someone only passes through a space. Test mode is what you use at commissioning to verify coverage before you leave the job. Presentation mode holds lighting on where normal occupancy detection would false-off, such as a conference room during a seated meeting.
7) Is the WattStopper PW-100 still the current model?
WattStopper lists the PW-301-I as the replacement part number for the PW-100. If you are standardizing a facility on one device going forward, note that; if you are matching sensors already installed across a building so the switches look and behave the same, the PW-100 is the direct match.
8) Where is the WattStopper PW-100 made, and does it have an environmental profile document?
Country of origin is China, and WattStopper publishes a product environmental profile for it. That combination matters on public and institutional bids where sourcing disclosure and environmental documentation get requested with the submittal package.
