Neptronic EVCB

VAV Unit Controller

What is the EVCB VAV unit controller used for in HVAC systems?

The Neptronic EVCB is a compact, all-in-one VAV unit controller engineered forprecise airflow management and seamless BAS integration. It supports BACnetMS/TP and Modbus RTU communications, making it a flexible choice for single-duct and fan-powered VAV applications.

With an integrated 70 in-lb (8 Nm) actuator, optional differential pressuresensor, and a menu-driven LCD interface, the EVCB delivers fastcommissioning, stable control, and dependable performance in criticalenvironments. Designed for field efficiency and long-term reliability, it combinesrobust construction, configurable I/O, and intelligent control logic tailored tomodern HVAC demands.

The EVCB aligns with Neptronic’s fully integrated design philosophy: reducingwiring, simplifying installation, and providing native interoperability across buildingautomation ecosystems.

 

Why choose the Neptronic EVCB VAV controller for zone control?

All-in-One VAV Control

The EVCB combines controller, actuator, and pressure sensor in one compact package: fewer parts, faster installs, and consistent performance every time.

Smarter, Faster Commissioning

Setup and balance directly from the digital room sensor. Copy and share configurations across devices in seconds to keep projects on schedule.

Flexible by Design

Adapt easily to any VAV application with configurable inputs and outputs for reheat, fan, temperature, or CO₂ control, all adjustable from the onboard menu.
