Indoor Sensor (CO2, Temperature, Humidity)

The WG AQS/TH-UP sensor transmits via wireless temperature, humidity and CO2 content in the air to the WS1 Colour/Style or (KNX) WS1000 Colour/ Style controller. Several sensors can be "taught" on one controller. The teaching procedure is described in the chapter "Learning wireless connections" (Controller manual).
The WG AQS/TH-UP consists of the housing, the sensor printed circuit board/baseplate, the CO2 sensor and a frame. As an alternative to the frame provided, a frame in the switch series used in the building can be used. You also need a junction box (Ø 60 mm, 42 mm deep, not included in the deliverables).
For the power supply (11...30 V DC) e.g. 12 V DC can be drawn from the connector board for the control system (multifunction-input).
