PRODUCT DATA
Integrated Room Control (IRC)
Featuring 0-10V Dimming and Demand Response Capabilities
FEATURES
• Stand-alone simplified daylight harvesting with
full range dimming
• Demand response capabilities
• 2 or 3 zone control for LED lighting
• Kitted with factory configured sensor,
DESCRIPTION
The Leviton Integrated Room Control (IRC) combines
single room occupancy sensing, daylight harvesting,
0-10V dimming, Partial ON, Partial OFF and demand
response capabilities into a single, easily installed
package. IRC features several methods of Ladderless
Commissioning™ for install-and-forget convenience,
including the AutoCal™ feature which automatically
sets the maximum light output levels and calculates
light loss factor for accurate lumen maintenance. The
IRC ships as either custom kits or a complete kit with
a factory configured occupancy sensor, photocell and
4-button switch. The 4-button switch provides ON,
raise, lower and OFF functionality. The performance,
features and capabilities of the IRC product provide
a simple and cost-eective stand-alone energy
management solution to maximize energy eciency
and meet energy code mandates for virtually any
commercial room control application.
