Twilight-/Temperature Sensor KNX [SCN-DTSEN1.01]

2.2 Functions

Light sensor
In addition to the current value in lux, the light sensor provides two separately adjustable threshold
values (1-bit switch or 1-byte scene). The threshold values can be locked by object. Due to the wide
measuring range of up to 100000 lux, the sensor, in combination with an MDT Shutter Actuator, is
also suitable for targeted shading of individual windows or facades.
Twilight sensor
The twilight sensor makes the "Day/Night" object available to the KNX bus via adjustable lux values,
the polarity ("1/0" or "0/1") is adjustable. This means, for example, that the MDT Glass Push Button
II Smart automatically switches to Night mode when it gets dark. Blinds or shutters can be raised or
lowered via the 1-bit switch object with an adjustable delay in the morning and/or evening with the
twilight.
Temperature sensor
The measured outdoor temperature can, as a 2-byte value or via one of the two adjustable
threshold values, for example, block or release the shading of the MDT Shutter Actuators. The
temperature can be displayed in a visualisation or e.g. on the Glass Push Button II Smart.
