Bluetooth brightness / temperature sensor
The Bluetooth brightness / temperature sensor is used for re-
cording brightness and temperature values. It can be adhered
on window panes without tools using an adhesive pad and is
operated with a lithium battery. It is thus independent of the
mains power supply and can be attached everywhere in the
room without interfering cables.
The wireless range in a room is approx. 10 metres.
The Universal Timer is expanded by various functions with the
brightness / temperature sensor.
Overview of the functions:
− Measured brightness and temperature values can be transmitted via Bluetooth to one or
more Universal Timers. Then the Universal Timer initiates the sun protection or the twilight
function and lets the blinds move to a defined position or switches / dims the lighting.
− Sends the current brightness value (in the range of 5 – 80,000 lux) via Bluetooth to the
Universal Timer
− Sends the current temperature value (in the range of -5 – +55 ºC) via Bluetooth to the
Universal Timer
− Sun protection function enables automatic lowering of a blind in the case of too strong
sunlight:
− Blind moves to the sun protection position if the brightness threshold is exceeded for longer
than two minutes
− Blind moves up again if the brightness drops below the threshold for longer than 15 minutes
− Brightness threshold can be linked with the temperature measurement. In this way, the shad-
ing is not initiated until a specified temperature and the brightness threshold are exceeded.
− Twilight function enables automatic lowering of the blind or switching / dimming of the
lighting
− Blind moves to the twilight position if the twilight threshold is undercut for longer than four
minutes
− Blind moves up again if the twilight threshold is exceeded for at least four minutes
− Lighting switches on if twilight threshold is undercut for four minutes
