Product Description
Leviton ODC0P-D0W Dimming Photocell
The Leviton ODC0P-D0W is an interior low voltage photocell capable of continually dimming between 1-10VDC based on the amount of natural light contribution. It is a lowpower, high-sensitivity mini-daylight harvesting system for precise monitoring of either task or ambient light levels. The ODC0P-D0W’s digital onboard microprocessor adjusts light levels by mimicking the spectral response of the human eye for single zone dimming. The ODC0P-D0W uses patented Daylighting Design Level (DDL) technology for precise load dimming that maintains desired light level. Ideal for existing retrofits and daylight harvesting applications, the ODC0P-D0W can be used with 1-10V sinking loads types and is a cost-effective solution when paired with dimming drivers/ballasts.
OPERATION
The ODC0P-D0W must be hard wired to a compatible Leviton 24VDC power supply to provide the photocell with power. The ODC0PD0W measures ambient light in a space and dims fixtures to a targeted lighting level in that specific area. Connection to optional power pack provides true ON/OFF switching.
FEATURES
• Dimmed lighting at a desired daylight design level offers greater energy savings and comfort and improved energy efficiency
• Leviton-exclusive, patented AutoCalibration™ eliminates the need for configuring labor costs during daylight harvesting configuration
• Industry-exclusive fail-safe circuitry: in the event of product failure, return-to-closed feature causes the relay to default to ON which eliminates life safety concerns
• Fade rate time setting 3-30 minutes
• Controls 0-10V sinking ballast
• No additional power supply required for 0-10V sinking operation
• Dim to OFF —over DDL for 30 seconds then lights OFF
• Test Mode—30 second fade rate for 15 minutes then auto exit
• Provides ultra-convenient, hands-free lighting control
• Measures light from any source in the visible spectrum within a 60º cone at 8-12’ mounting height
• Provides continual measurements to control the lighting
• Mounts on ceiling —surface mount or lowprofile flush mount
• LED status indicators for ease of installation
• Can be used to comply with IECC, ASHRAE 90.1 and Title 24, Part 6 0-10V dimming and daylight harvesting requirements
INSTALLATION
- Low Voltage Class 2 Wiring
• Connects directly to an OPP20 Series Power Pack (OPP20-RD3 or OPP20-RD4) and 0-10V dimming ballasts
• May be installed directly above workspace
• Use with standard Class 2 wiring
OPERATION
• Measured light level Target Level Action: Lights level decreases
• Control output state (Orange wire): - Photocell not calibrated, factory default state: lights ON, output is 0V - Photocell calibrated, light needed state: lights ON, output is 0V - Photocell calibrated, light NOT needed state: lights OFF, output is 12-24V
