Light sensor
Together with the SOMFY Chronis Uno L, Chronis IB L and Chronis RTS L, the SOMFY
brightness sensor can be used to operate your roller shutters and venetian blinds in relation to
the amount light. These SOMFY control units have an integrated automatic solar control unit (L
= light control) that automatically creates shade if the sunshine is too strong.
In addition, the SOMFY Chronis Uno L and Chronis IB L offer an automatic dusk control unit
that operates your roller shutters and venetian blinds in conjunction with the switching time
when dusk sets in.
Insert the plug of the
brightness transmitter into
the socket on the front of
the Chronis L control unit.
Stick the suction cap of the
brightness sensor to the inside of
the window pane at the desired
shade position of the roller
shutter.
