Room setup

· RDU341 or RDG400KN, Room thermostat: The room thermostat measures the room temperature and

calculates the heating / cooling demand which is sent to the heating / cooling controller and to the VAV

controller. It also controls the valve actuator STA23 of the floor heating.

· GDB181.1E/KN, VAV controller: The GDB… controls the VAV dampers. It’s air volume setpoints are

shifted according to the air demand from the room thermostat.

· AQR2576, air quality sensor: The AQR2576 sends the air quality data to the air handling controller

which controls the fresh air quantity of the supply air. The AQR offers two digital inputs to connect a

standard wall switch to operate lights and blinds.

· UP 258E21, presence detector: The UP 258 detects occupancy in the room and measures the

brightness. These data are distributed to the room thermostat and the KNX/DALI gateway.

· N 141/02, KNX/DALI Gateway: The N 141 transfers the KNX signal to the DALI bus to switch and dim

the lights. In the other direction it sends status information such as the failure or operating hours of a lamp

to the KNX bus.

· N 523/04, blind actuator: The N 523 is controlled by the weather station and drives the blinds and its

slats to the required position.

· AP 257/22, weather station: The AP 257 measures the outside temperature, brightness and windspeed

and calculates drive commands for the blind actuator.
