Page 2: Unit Description
UNIT DESCRIPTION The Watt Stopper UT-300 sensors turn lighting systems on and off based on occupancy. The UT-300 can be confi gured to turn lighting on, and hold it on as long as it detects cccupancy. After no movement is detected for a user specifi ed or SmartSet time (5 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
WIRING DIRECTIONS CAUTION TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE INSTALLING POWER PACKS OR SENSORS. Each Watt Stopper BZ series power pack can supply power for 4 UT-300 sensors. When using more sensors than this, multiple power packs are required. - Page 5 Standard wiring with local off switch Line Voltage Wire Color Legend Line Feed Through Neutral Black White Load #1 Power Pack Low Voltage Load #2 Class 2 (Optional) Line Black Voltage Common Blue Control Out +24V Ceiling Depluggable Terminal Spring Clips (2) Rear Housing Line Voltage Switches...

Page 8: Sensor Adjustment
SENSOR ADJUSTMENT The sensors are factory preset to allow for quick installation in most applications. Verifi cation of proper wiring, coverage, and customizing the sensor’s settings can be done using the following procedures. To make adjustments, open the Front Cover with a small screwdriver. -
Page 9: Dip Switch Setting
On Mode: Switch 1 Override The Manual ON function is facilitated by installing Normal a momentary switch such as a Watt Stopper LVS-1 Override Momentary Toggle Switch, or RS2-3 Low Voltage Momentary Switch. This switch connects to the Time Delay 3 4 5 sensor’s Manual (Man.) Switch and Common terminals... -
Page 10: Override: Switch
Override: Switch 2 To override all sensor functions, set DIP switch 2 to the ON position. The green LED comes on and stays on for the duration of the override. This bypasses the occupancy detection control functions of the sensor, but still allows the lights to be manually controlled with a light switch, if one is installed. -
