General information
The SMS 2 or SMS U2 are used together with the SW 4 wind
sensor and the SL 2 light sensor for safe and convenient
control of awnings or external blinds.
When the sun intensity is high, the awning is extended auto-
matically, and retracted again when the brightness decrea-
ses (this automatic function can also be deactivated).
If the wind speed is too high, the awning is retracted automa-
tically.
The SMS 2 also has an integrated twilight function and a
blind reverse function.
Buttons for direct OPEN/CLOSE operation can be connec-
ted. The automatic shading system can be deactivated for a
certain period of time by pressing an operating button for a
longer period of time.
Wind monitoring always has priority, so system safety is gua-
ranteed even in the event of incorrect operation.
Applications
Convenient automatic shading control with additional protec-
tion against wind damage to electrically operated awnings.

SMS 2
(rail mounting version)
SMS U2
(flush mounting version)
SMS 2 has an additional automatic twilight function for night-
time room darkening.
Operation
The desired response thresholds are set with the „Sun" and
„Wind" (and „Twilight" at SMS 2) settings.
When a set limit value is exceeded, the control LED starts
flashing and the awning is activated after the response time
has elapsed. The details of the individual operating modes
can be found in the function diagrams.
The awning can also be operated manually by a directly
connected dual push-button (without mutual interlock). The
response time of the automatic shading function is reset
after each manual operation.
In order to manually force the awning to remain stable for a
long period of time, a long press (5 seconds) of the OPEN or
CLOSE button can completely deactivate the sun automation
for 5 hours. Pressing the button during this time reactivates
the automatic sunshade function.
