DESCRIPTION AND OPERATION
The UW Ultrasonic Wall Switch sensors employ 40kHz
ultrasonic technology in a single-gang wall switch unit. The
UW sensor can turn a load ON, and hold it ON as long as the
sensor detects occupancy. After no movement is detected for
the selected time delay, the lights switch OFF. 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 UW-100 has one relay and one ON/OFF button. The
UW-200 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.
UW 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 UW-200, light level
only affects the load on Relay 2. Users can overrule this
function by pressing the ON/OFF button. See Light Level
Adjustment.
Turning ON the Load (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
** UW-100: Switch 8 is not used. UW-200: Switch 8 default is ON to comply with CA Energy Commission Title 24 bi-level switching
requirements.
Model # Relay Default ON Mode DIP Switch # Setting
UW-100 1 Manual ON
UW-200 1 Auto ON
2 Manual ON
NOTE: Shaded cells in the following tables indicate default operation and switch setting.
Presentation Mode
This is a feature of the Auto ON mode.When both relays are manually turned OFF the UW holds the lights OFF until no motion has
been detected for the duration of the Time Delay. With subsequent occupancy, the UW turns the load ON. If both relays are ON and one
relay is manually turned OFF this relay remains OFF until both the Time Delay and retrigger delay expires for the relay that is ON, after
that time the ON Mode control settings again apply.
Time Delays
The UW sensor holds the load ON until no motion is detected for the selected time delay. Select the time delay using DIP Switch
settings. In the UW-200, both relays use the same delay.
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 re-triggers during the delay (see Trigger Mode), 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.
