New technologies such as IoT (Internet of Things) and BIM (Building Information Modeling) and the resulting diverse possibilities are or are already in the process of significantly expanding the horizon of building automation (BA).

As a result, modern, forward-looking buildings are making fundamentally new demands on their BA systems, their functionality, network, data and handling.

ECOAIR Controller is used to implement efficient automation solutions in all areas of modern building and room automation.


ECOAIR Controller includes solutions for connecting building automation to cloud and IoT services.

Graphical Web Server

The graphic web server on board of the ECOAIR Controller allows autonomous communication of the automation system with the user via a standard web browser. Through the graphical web server, the entire operation of the equipment of the technical building equipment is carried out by means of dynamic graphics, including alarm management, trend and visualization of the equipment.


Modern wireless technology via WLAN with optional USB WLAN adapter ensures convenient operation of the automation station on site via mobile devices such as smartphones, tablets and notebooks.


HTTPS ensures secure data transmission.

SD Card

The SD card allows the storage of relevant project and automation data as well as historical trend data directly on site without a management system.


ECOAIR Controller can be used as a BACnet® Building Controller (B-BC) according to the BACnet® Standardized Device Profile according to Annex L of the ANSI ASHRAE standard 135-2001. Communication takes place via BACnet / IP and BACnet MS / TP. BACnet Building Controller B-BC, Protocol Rev. 1.15 AMEV profile AS-B according to "BACnet 2017" (identical to BACnet 2011 V1.2)


As the central unit of the building automation network, ems5 integrates all components of the building automation system into the building automation system. Extensions via ems4 integration modules enable connections to KNX, DALI, Modbus, M-Bus, OPC, Profibus, SMI, EnOcean as well as to manufacturer-specific systems such as Grundfos, Wilo, Belimo MP-Bus, Schüco, ebm-papst and others.


The increased performance within the CPU and memory of the ems5 guarantees short reaction times and also enables the implementation of complex mathematical calculations and algorithms, the basis for exceptionally efficient building solutions and instrumentation and control technology.

Implementation of "Smart Building"

ECOAIR Controller includes pioneering automation and control strategies for the implementation of "smart buildings" - efficient, flexible and sustainable.

Multi-functional Concept

Like its predecessors, the ems5 automation station is compact and modular at the same time as the 14 inputs are freely configurable as PT / NI1000, 0-10 VDC or DE 24 VDC. Also onboard are 4 analog outputs 0-10VDC and 6 floating relay outputs 230VAC / 6A.
