ECB and ECL 50 Series BACnet and LonWorks controllers with live graphics color displays allow users to quickly view, edit, and configure an HVAC system’s operating parameters, while color-coded icons and highlights provide at-a-glance indication of alarms and override conditions. The controllers’ local human-machine interface facilitates system troubleshooting and diagnostics without the need for a laptop. 50 Series models range from the ECB and ECL 253 for rooftop units, to the ECB and ECL 650 for central-plant applications. —Distech Controls
