The Z1000 Bypass Package is optimized with an Intelligent Bypass and advance BAS interface. The design sets a new benchmark for performance, benefits and quality. The Z1000 Bypass is BTL listed, view listing.
The Intelligent Bypass, when enabled, can transfer the motor across the line when the application requires 60Hz. Most HVAC systems require 60Hz at peak demand (Summer months – daytime), which will utilize the intelligent bypass function. Removing the drive at 60 Hz saves energy and removes harmonics at worse case conditions.
