Unit Description And Operation - wattstopper DSW-301 Installation Instructions Manual

UNIT DESCRIPTION AND OPERATION

The DSW Dual Technology Multi-Way Wall Switch sensors combine advanced
passive infrared (PIR) and ultrasonic technologies into one unit. The combined
technologies help to eliminate false triggering even in difficult applications.
Selectable operating modes allow the sensor to turn a load ON, and hold it ON
as long as either or both technologies detect occupancy. It allows for up to 4
sensors to be connected to the same circuit. The first sensor to detect occupancy
will turn ON all the lights that are connected to the same circuit. After the room
is unoccupied, the last sensor that detected occupancy turns OFF all the lights
once the time delay has expired. The occupant can turn OFF the load at any time
by pressing the ON/OFF button of any sensor that is connected to the circuit.
A "walk-through" mode can turn lights off after only 3 minutes if no activity is
detected after 30 seconds following an occupancy detection.
The DSW-301 has one relay and one ON/OFF button. The DSW-302 contains two
relays and two ON/OFF buttons to allow control of one or two loads independently.
Pressing a button toggles the state of the corresponding relay. Optional Neutral is
also available on all models.
DSW sensors contain a light level sensor. If adequate daylight is present, the
sensor holds the load OFF until light levels drop, even if the area is occupied. In
the DSW-302, light level only affects the load on Relay 2. Users can override this
function by pressing the ON/OFF button. See the Light Level Adjustment section.
Turning Load(s) ON (ON Mode)
The relays are programmed independently for either Auto ON or Manual ON. In
either mode, the load can be turned ON or OFF using the ON/OFF button.
Manual ON
DIP 8 ON for Relay 1
DIP 9 ON for Relay 2
Auto ON
DIP 8 OFF for Relay 1
DIP 9 OFF for Relay 2

With an ON Mode DIP switch in the ON position, the
occupant must press the ON/OFF button to turn
ON the load. The sensor keeps the load ON until no
motion is detected for the selected time delay. There
is a 30 second re-retrigger delay. If occupancy is
detected during the delay, the sensor turns the load
back ON. After the re-trigger delay elapses the ON/
OFF button must be pressed to turn ON the load.
With an ON Mode DIP switch in the OFF position,
the load turns ON and OFF automatically based
on occupancy. If the load is turned OFF manually,
Presentation Mode operation applies. This prevents
the load from turning ON automatically after it was
deliberately turned OFF. Pressing the button to turn
lights ON returns the sensor to Auto ON mode.
