Mounting
Remove empty batteries immediately and dispose of in an environmentally friendly
manner. Do not throw batteries into household waste. Consult your local authorities
about environmentally friendly disposal. According to statutory provisions, the end
consumer is obligated to return used batteries.
Selecting installation location
To ensure good transmission quality, keep a sufficient distance from any possible sources of in-
terference, e.g. metallic surfaces, microwave ovens, hi-fi and TV systems, ballasts or trans-
formers.
Depending on the intended application, whether as a brightness sensor for shading or as an ex-
ternal temperature sensor for the temperature controller, the installation location must be selec-
ted.
Operation as brightness sensor: Select the installation location on the window pane so that the
sunlight hits the sensor unobstructed even when the sun protection is active. Shadows produce
incorrect measured values.
Operation as temperature sensor: Select an installation location on furniture or walls so that
draughts or air turbulence caused by heat sources do not disturb the measured values.
We do not recommend mounting on uneven surfaces such as rough wallpaper, plaster-
board, structured vinyl wallpaper or fabrics.
Mounting the sensor
The contact surface of the substrate must be dry, clean and free of grease. When mounting on
walls or furniture, the surface must be as smooth as possible.
￭
Apply adhesive pad (5) to underside of housing (Figure 7). Remove the protective film on
one side, place it on the underside of the sensor housing and press it down firmly. The
light guide (4) for brightness measurement must not be pasted over.
￭
Remove the protective film from the adhesive pad, place the sensor on the surface and
press firmly.
Dismounting the sensor
￭
Detach the sensor from the surface by rotating it alternating clockwise and counterclock-
wise.
