AHU CONTROLLER EAIR 100 PLC

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 ventilation 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 ventilation process. Expandability is implemented through add-on IO modules. The eAir controller comes standard with Modbus RTU and TCP/IP interfaces, enabling integration with monitoring sub-stations, cloud monitoring systems, or energy management services from various manufacturers. eAir110 Controller - eAir110 is a ventilation controller - Compatible with the additional IO eAir120 - eAir110 is a DIN-rail mountable module component (8 modules) - eAir110 is ordered as a separate product and installed into the enclosure - Additional options - eAir110 can be ordered with the eAir120 additional IO to expand the required IO quantity Functional Features - Damper motors: two-position or adjustable - Filter monitors: either alarm-only or measuring; measuring types also provide airflow alarms and sliding limits - LTO can be rotary (disc), plate (cube), or liquid (glycol) - Fans: either 1- or 2-speed or continuously variable (SC or EC) - Control of adjustable fans via standard message, pressure control, or airflow control - Three heating stages: heat recovery wheel, LTO, and heating coil - Cooling coil control and regulation - Room temperature, carbon dioxide, and humidity measurement - Additional time button, boost, and night heating function - Sensor fault alarms and upper/lower limit alarms for temperature, pressure, and differential pressure measurements - Fan and pump conflict alarms - Freeze protection acknowledgment button and indicator light - Pre-heating coil - Plate LTO defrosting Other Features - Clear graphical display and five buttons - Ethernet RJ45 connector - Two RS485 interfaces - SD card slot - Freely configurable IO - Widely compatible sensors - Connectable to monitoring systems or cloud services Ethernet Features - Email alerts - WebVisu - Modbus TCP/IP (optional BACnet IP) - IO points - 12 x relay outputs - 12 x digital inputs - 12 x analog inputs - 6 x analog outputs This product description is an automated translation of the original Finnish description.
