Terminal wiring for quick and easy installation

Architecturally appealing low profile appearance

Operates at 120, 277 or 347 VAC, 50/60 Hz

Walk-through mode increases savings potential

Auto set automatically selects optimal settings for each space

Ultrasonic diffusers give more comprehensive coverage
