Advanced Rooftop Controls (ARC)

Manage your rooftop units more efficiently

An Advanced Rooftop Unit Control (ARC) is an energy-saving retrofit solution for constant volume, single-zone packaged rooftop equipment. These controls work with various rooftop unit (RTU) manufacturers, have the ability to control and monitor RTUs via the Internet, and can reduce utility expenses by more than 50 percent. For more details about the ARCs, please download our ARC fact sheet.

PSE, Seattle City Light, Snohomish County PUD and Tacoma Power offer energy rebates, up to 100% of the total cost, for adding Advanced Rooftop Controls to constant volume rooftop units.
