Function and device overview

An additional relay output enables the device to control a

connected consumer, e.g. a lamp. The light can be easily

switched via remote controls, wall-mounted push-but-

tons, motion detectors or via the Homematic IP app. A

ﬂush-mounted box can thus be used simultaneously for

the CO2 sensor and for light control.

Thanks to its 55 mm design, the sensor can be easily

integrated into existing frames of common brand man

ufacturers. The design, colours and surfaces of switches

already installed remain unchanged.
