AHU CONTROLLER EAIR 100 ENCLOSURE M12

The installation of the eAir controller is designed to be as hassle-free as possible. The controller can be configured directly from the controller panel, touchscreen, or via the controller’s web interface. The controller comes with pre-set configurations for the most common HVAC unit variations, such as LTO models, pressure control, heating, and cooling. The eAir unit controller differs from traditional sub-stations in that it includes factory-programmed and thoroughly tested control programs. The installer activates the control programs as needed, and all parameters are adjustable to match the desired HVAC process. Expandability is implemented through add-on IO modules. The eAir controller standardly includes Modbus RTU and TCP/IP interfaces, enabling integration with control sub-stations, cloud monitoring systems, or energy management services from various manufacturers. eAir100K Enclosed Controller
