Page 2: Unit Description
UNIT DESCRIPTION The WattStopper UT-300 sensors turn lighting systems on and off based on occupancy. The UT-300 can be configured to turn lighting on, and hold it on as long as it detects cccupancy. After no movement is detected for a user specified time (30 seconds to 30 minutes) the lights are switched off. -
Page 3: Placement Guidelines
PLACEMENT GUIDELINES Depending upon obstacles such as furniture or partitions, the area of coverage may be less or more than the sensing distances shown in the coverage pattern. This must be considered when planning the number of sensors and their placement. It is also recommended to place the sensor 4 to 6 feet away from air supply ducts. - Page 4 WIRING DIRECTIONS CAUTION TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE INSTALLING POWER PACKS OR SENSORS. Each WattStopper BZ series power pack can supply power for 5 UT-300 sensors. When using more sensors than this, multiple power packs are required. Refer to the wiring diagram on the next 03620r2 UT-300...

SENSOR ADJUSTMENT This unit is pre-set for basic operation as described in this guide. Adjustment is optional. The sensors are factory preset to allow for quick installation in Keyhole slots most applications.

It will not turn the lights off if they are on. The default setting is for maximum, meaning that even the brightest ambient light will not hold the lights off.

again by occupancy detection or switch activation. b. Activating the manual switch while the load is ON turns the load OFF. • When the load is turned OFF manually, as long as the sensor continues to detect occupancy the load stays OFF. For the selected time delay, the lights stay off and the sensor reverts to the automatic-on mode. - Page 13 Lights do not turn off automatically 1. The sensor may be experiencing activations from outside the controlled area or from some type of interference (see “Unwanted Sensor Activations” below). 2. Check all sensor wire connections. 3. Disconnect power pack’s blue wire: If the lights do not turn off, replace power pack.
