The Z1000 family of HVAC drives includes the Z1000 variable speed drive for building automation applications such as fans, pumps, and cooling towers through 500 HP. The Z1000 Bypass Package, designed specifically for commercial HVAC applications, is optimized with an Intelligent Bypass and advance BAS interface. 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.
