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.

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

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

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

Native BACnet MS/TP or Modbus RTU ensures effortless connection to any building automation system, with auto-baud detection and firmware updates that keep you current.

Field-proven algorithms and pressure-independent operation deliver stable airflow, tight temperature control, and energy-efficient comfort in every zone.

Rugged 24 Vac design, thermal protection, and removable terminals make the EVCB as reliable on-site as it is intelligent in operation.
