Electronically Controlled Bypass
The Danfoss Electronically Controlled Bypass (ECB) incorporates HVAC-specific features such as automatic bypass, common start/stop, coordinated run-permissive, and serial communications over the BAS as standard. Unique among microprocessor-based bypass products, the ECB uses the same keypad for both drive and bypass functions. The ECB centralizes I/O and logic tasks into the VFD package. In many cases, this means retrofit installations can easily take advantage of new functionality with minimal changes to the BAS system. Using the next generation VLT HVAC Drive, now available with BTL -certified BAC net, the ECB represents Danfoss’ ongoing commitment to customer applications.
