BACnet room controller KTRBUu Flush-mounted installation – Design Berlin UP
Technical data
Application
Design:
Berlin UP (flush-mounted) PC, PMMA, ABS plastic
The alre BACnet individual room controller with graphic display was specially developed for time-dependent heating and cooling operation in 2- or 4-pipe systems. The controller can be used in a wide range of applications, such as hotels, residential, office and business premises as well as hospitals and schools. The communication takes place via BACnet according to DIN EN ISO 16484-5 with the BACnet MS/TP network protocol. The room controller is therefore compatible with all com- mon building automation systems. The control- ler corresponds to the BACnet profile “B-AAC” (BACnet Advanced Application Controller). The predefined applications cover a wide range of applications for room temperature control in room automation. Special colours are available for projects as well as the colors anthracite and aluminum on request.

* Depending on the selected system scheme, a menu setting can be used to select whether control should be based on the internal or external sensor. In the intermediate positions, if both sensors are used, a weighting is applied to the internal room sensor and the external temperature sensor. The weight- ing allows for compensation of different structural conditions such as large window areas or cardinal directions. For very slow controlled systems, it is recommended to assign a higher weighting to the temperature sensor than to the internal room sensor.
