The ECL-VAV series are microprocessor-based programmable variable air volume (VAV) controllers designed to control any variable air volume box.
This series contains five models as follows: ECL-VAVS-O, ECL-VAVS, ECL-VAV, ECL-VVTS, and ECL-VAV-N. Models with inputs support various measurement types including resistance, voltage, and digital-based ones. All models provide digital, floating, pulse width modulation, and proportional control outputs for valves, heating elements, fans, and lighting applications.
All controller models work with the EC-Smart-Vue series of communicating sensors that feature a backlit display and graphical menus. These sensors are used for indoor temperature measurement, setpoint adjustment, and occupancy state override. An EC-Smart-Vue can be used to perform system air balancing without requiring an onsite controls engineer and to commission and troubleshoot the system. In addition, all controller models are Open-to-Wireless™ ready, and when paired with the Wireless Receiver, they work with a variety of wireless battery-less sensors and switches.
Factory preloaded applications allow these controllers, straight out of the box, to operate standard VAV equipment with a proven energy-efficient sequence of operation thereby eliminating the need for programming. The preloaded application can be selected using an EC-Smart-Vue even before the network has been installed for rapid deployment or through the EC-NetAX solution using Distech Controls’ dcgfxApplications.
