BACNET ROOM CONTROLLER KTRBUU FLUSH-MOUNTED INSTALLATION – DESIGN BERLIN UP
TECHNICAL DATA
APPLICATION
Design:
Berlin UP
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 common building automation systems. The controller 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 as well as the colours anthracite and aluminium are available for projects upon 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 weighting 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.
