ADJUSTMENTS

Sensor Adjustment

R e m ove the wall plate. Remove the button cap by firmly squeezing together the
top sides of the button ass e m b ly. Gently pull it away from the unit.
When the adjustments are co m p le ted, re p l a ce the button cap by inserting its
hinges into the tabs on the main unit and then squeeze the top of the button while
p re ssing it into the unit. Reinstall the cover plate .
Light Level Adjustment
The light level can be set with loads ON or OFF. To enable light level co n t rol and
set the threshold: 1) Make sure the room is lit appro p r i a te ly. 2) Put the sensor into
TEST mode. You have 5 minutes to co m p le te the pro ce d u re. 3) Pre ss and hold the
ON/OFF button (Relay 1 b u t ton on the UW-200) for 3 seconds, until you hear a
beep. 4) Step away from the sensor. After 25 seconds a beep sounds, indica t i n g
that the threshold level is set. This threshold is re tained, even if power is lo st ,
until it is re-set or disabled. In the UW-200, light level co n t rol only affects Relay 2.
To disable light level co n t rol, pre ss and hold the Relay 1 b u t ton for 7 seco n d s,
until a double beep tone sounds.
Reset to Default
To reset the UW to fa c tory settings, pre ss and hold the Relay 1 b u t to n for 1 0
s e co n d s, until a triple beep sounds. This resets the sensor occupancy history and
d i s a b les light level co n t rol (the brighte st ambient light will not hold the light OFF).
