Page 2: Unit Description
SmartSet automatically adjusts the time delay to usage patterns in the controlled space. The UT-305 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 or SmartSet time (5 to 30 minutes) the lights are switched off. -
Page 3: Placement Guidelines
4 to 6 feet away from air supply ducts. Mount the sensor to the ceiling. The UT-305 is designed for a ceiling height of about 8-10 feet. Mounting above or below this range will significantly affect the coverage patterns. -
Page 4: Wiring Directions
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 4 UT-305 sensors. When using more sensors than this, multiple power packs are required. 03624r2... - Page 5 Neutral 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 Front Cover UT-305 Visit our website for FAQs: www.wattstopper.com...

5. Push the sensor up into the J -Box and twist it so that the mounting screws are seated in the keyhole slots. 6. Tighten the two screws to secure the sensor to the J-Box. 7. Snap the front cover onto the sensor. Visit our website for FAQs: www.wattstopper.com... -
Page 8: Sensor Adjustment
SENSOR ADJUSTMENT The sensors are factory preset to allow for quick installation in most applications. Verification of proper wiring or coverage, or 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
Logic Configuration Chart DIP SWITCH SETTING The UT-305 has 6 DIP switches. They are used On Mode to set manual/automatic on/off functions, time delay and sensor activation LED settings. Auto On Manual On On Mode: Switch 1 The Manual ON function is facilitated by Override... -
Page 10: Override: Switch
ON and the sensor reverts to the automatic-on mode. • Once the sensor returns to automatic-on mode, either the switch or occupancy detection can turn the load ON. 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. -
