1.
RDG400KN room thermostat: The RDG400KN acquires the room temperature and calculates the
request for heat/cooling energy sent to the heating/refrigeration and VAV controllers. It also controls valve
actuator STA23 of the floor heating system.
2.
QMX3.P70 room operator unit: The QMX3.P70 acquires the indoor air quality and sends its value to the
ventilation controller which adjusts the amount of fresh air required.
3.
GDB181.1E/KN VAV compact controller: The GDB.. controls the VAV dampers. The setpoints of the
volumetric air flow are shifted depending on the amount of air demanded by the room thermostat.
4.
N 141/02 KNX/DALI gateway: The N141 transmits the KNX signal to the DALI bus to switch and dim the
lighting. In the other direction, status information, such as error messages or operating times of lamps, is
sent to the KNX bus.
5.
N 523/11 blind actuator: The N 523/02 features 8 channels to control up to 8 blind motors.
6.
UP258E21 presence detector with constant light control: The UP258E21 acquires room occupancy
and brightness. This information is then forwarded to the room thermostat and the KNX/DALI gateway.
7.
UP 223/2 pushbutton, triple, neutral: The UP 223/2 is used to control the lighting and/or the blinds.
