The radio-controlled sensor for carbon dioxide is used to
measure the CO
2
content in a room. The sensor is located in an
adapter housing and runs on the mains power supply. As soon as
the CO
2
content exceeds a defined level, a switching
command is sent to taught-in HomeMatic actuators. The CO
2
content continues to be measured; a second switching command
is sent accordingly after 20 minutes and 10 minutes respectively.
The following example illustrates the process.
Example:
If the air quality sensor for CO
2
measurement has been taught-in
directly on a WinMatic, for example, when the sensor sends a
switching command on account of the high CO
2
content, the
WinMatic will open the window for 20 minutes to ventilate the
room. Should the CO
2
content in the air drop after this time (in
other words, if the air becomes fresher), the WinMatic will close
the window automatically. If the air does not improve after the
first 20 minutes of ventilation, the window will be kept open for a
further 10 minutes.
