OMX-DACPI Automatic Daylighting Control
Description
• Saves energy in spaces with windows,
skylights, or doors. Automatically dims
lights when the sun is bright.
• Monitors ambient daylight via Lutron’s
MW-PS-WH photosensor or 0-10V
photosensor by others.
• Automatically selects scenes based on
the amount of daylight available.
• Helps maximize energy savings with
“enforce” mode – automatic control
overrides lighting set by occupants.
• Eliminates “passing cloud” effect with a
two-minute “range qualification” timer.
• Works with GRAFIK 5000, 6000, and
7000 Systems.
Functionality
• In the OMX-DACPI Daylighting Control,
thresholds are set to define different
ranges of daylight.
• The OMX-DACPI monitors ambient
light, automatically selecting scenes as
daylight levels cross thresholds.
• The OMX-DACPI allows setup of four
“banks” of thresholds and scenes.
• Three different thresholds can be set
up for each bank.
• Use the bank select keys to select
which bank the OMX-DACPI uses.
• The OMX-DACPI automatically selects
scenes based on the bank selected
and the amount of daylight available.
This provides 12 different thresholds
that call 16 different Control Unit
lighting scenes. Create thresholds and
scenes for different times of the day
(morning vs. afternoon) or year (winter
vs. spring).
