· RMB795B, Central control unit: Central control for 10 rooms / room groups via KNX.

· QMX3.P70, Room unit with room temperature controller and CO2 sensor:

Measures and controls the

room temperature and sends the control commands to the switching actuator. The air quality is displayed

by a color-changeable LED.

· S 290, Door-/Window contact: Detects the status of the window/door and sends the value to the room

temperature controller.

· N 562/11, Switching actuator, main module: Controls up to 3 heating circuit.

· STA23, Electrothermal actuator: Controls the radiator valve.

· UP 258E21, Presence detector: Detects presence of people and measures the brightness in the room.

Control commands are sent to the light actuator and to the apartment unit. The presence detector makes

sure that the artificial light is off when the room is not occupied or when enough natural light is available

and the room operating mode is switched to pre-comfort (reduced temperature setpoint).

· N 141/31, KNX/DALI Gateway Twin: Controls the lights on the DALI bus.

· N 523/11, Venetian blind actuator: Controls the blinds according to the received commands.

· UP 222, Wall switch: For operation of the lights and blinds.

· AP 257/22, Weather station: Measures the wind speed and the brightness. When exceeding the speed-

limit the weather station sends a command to the blind actuator to drive into a safe position. When the sun

is shining the blinds are driven into a position to keep off the sun radiation. The weather station supports

the functions sunlight tracking and shadow outline tracking.

· RMH760B, Heating controller: The heating controller controls the heating plant in dependence on the

heating demands sent by the central apartment units.

· OZW772.16, Web-Server: The web server offers a central remote operation of the heating, lighting and

shading of the whole building.

Raumtemperatur-

regelung

The temperature of each classroom is acquired and controlled. The heat demand from each room is acquired and

transmitted to the primary plant. Non-occupancy periods during the night can

be programmed for each room. During

these time periods, the room temperatures are automatically reduced. Open windows are automatically detected

and room temperatures lowered to save heating energy. Also during the day when the rooms are not occupied, the

room temperatures are slightly lowered.

Air quality monitoring

The air quality sensor measures the CO

concentration in the room air and shows the measured value via a high-

lighted LED on the front of the device. A red lighted LED indicates that the room shall be supplied by fresh air.
