Both electronically controlled bypass (ECB) and electromechanical bypass (EMB) designs are available in the VLT HVAC packaged-drive solutions. ECB packages allow users to program advanced bypass control features directly from the VLT HVAC drive keypad, including automatic bypass, coordinated run-permissive in both drive and bypass, and serial control while in bypass operation. The EMB packages are for users that prefer the traditional control provided through selector switches and pilot devices.
