This is a powerful building automation controller which can be user programmed to control any typical HVAC application including coolers, boilers, vavs, and air handlers. The front end software supports building floorplans, mechanical diagrams and live data from the building. The configuration software and the building operator software are free so there are no license fees and no monthly cloud service fees. The controller can operate as a stand alone device or it can be networked together with many other devices covering many buildings. All communication are carried out using industry standard BACnet and Modbus protocols. With an open source front end and open source code of the hardware itself, there is no system like it on the market.
Each controller has a RS485 port and an optional Wifi port. MODBUS and BACnet protocols are supported on all these ports. The controllers can be integrated into other environments from the big names such as Honeywell, Siemens, Johnsons, Kreuter and Sauter to name a few.
