Single room unit with BACnet MS/TP

Whether for office or hotel rooms, in wellness areas, hospitals, schools or universities: the OPEN SRU (Single Room Unit) takes over the entire room control in different types of buildings. The single room unit can be used for integral control of HVAC, shading and lighting in all areas of room automation. Sensors and actuators can be connected via the standardised Modbus or KNX interface. The open interfaces also enable the flexible use of modern touch control devices from different manufacturers. The 8 universal inputs as well as 4 universal and 4 digital outputs provide the flexibility to cover the required range of tasks: temperature, presence detector, air quality, set-point, window contacts, valves or volume flow controller.

You decide whether you want to program the SRU freely or whether you want to use the preconfigured and time-saving DEOS libraries. By using the template or macro library, you can significantly reduce your programming work and avoid programming errors.
