Scheme Status Day* Night* Description
ON/OFF Vacant OFF OFF Lighting will be inhibitedwhen theambient lightlevelishigherthan the set
threshold, regardless ofoccupancy or vacancy. When theambient light
level is lower thantheset threshold,the controlledlightwillbe turnedon
automatically once the sensor detectsthepresence of occupant, and
turnedoff afterthedelaytimeelapsed.
NOTE:This is a typical occupancy sensing control scheme can be used
withdimmable or non-dimmable lighting, but not HID.

Wheneverspaceis occupied, lighting outputwill be increased toHigh Dim
level orcontinuously regulated to maintain within thepre-set rangeby
SmartDIM control.
NOTE:This is anoccupancy sensing control scheme can be applied in
areasthatrequire 24-hourlighting.

Lightingwill be inhibited if theambientlight level is higher than theset
threshold, regardless ofoccupancy or vacancy. When theambient light
level is lower thanthe set threshold, thesensorwill automatically control
the lightat LowDim level. Whensensordetects thepresenceof an
occupant, lighting output will be increased to the High Dim levelor
continuously regulated within the pre-setrangeby SmartDIM control. After
thedelay timeelapsed,lighting outputwill be reduced to Low Dim levelor
shut off if the ambientlightis higher than thesetthreshold.
NOTE:This is anoccupancy sensing control scheme can be applied in
spaces that require automatic lighting whenever ambient light level is
lowerthan the set threshold.
Do NOT usewithnon-dimmable lighting.

Lightingwill be inhibited if theambientlight level is higher than theset
threshold, regardless ofoccupancy or vacancy. When theambient light
level is lower than theset threshold,andany sensordetectsthe presence
of occupant, lightingoutputwill be increasedtoHigh Dim level or
continuously regulated to maintain overall lightinglevelwithin the pre-set
range by SmartDIMcontrol. After thedelay time elapsed, lighting output
will bereduced toLow Dimlevel for aperiodof TIMEOFFdelaybefore shut
off.
NOTE:This is anoccupancy sensing control scheme can be applied in
spaces that require maintainingLow Dimlightingfora period oftime

Thisschemerequiresdimmable lightingto enabledimming control. If
lighting is non-dimmable, thecontrolledlights will be shut off afterthe

Lightingwill be inhibited if theambientlight level is higher than theset
threshold. When theambient light level is lower than the set threshold, the
sensor will turn the light to High Dim level or continuously regulate the
output tomaintain overall lighting levelwithinthepre-set rangeby
SmartDIM control. Lighting output will be reducedtoLow Dim levelfrom a
certain timebeforevirtual midnightto a certain timeafter.
NOTE:This is a daylight sensing control scheme can be applied in spaces
thatrequire automaticallydimmingthelight to alow levelbetween a
certain time before and after virtual midnight. This scheme requires
dimmable lighting toenable dimmingcontrol. If lightingis non-dimmable,
the controlled lighting will remainfull on whenever theambientlight level
is lower than the set threshold.
