SOMFY THERMO SUNIS INDOOR WIREFREE RTS SUN SENSOR - Manual (Page 2)

Thermosunis Sensor for INDOOR USE ONLY
™ INSTALLATION: MOUNTING THE THERMOSUNIS WIREFREE RTS SENSOR TO WINDOW OR SILL
1. Attach the ‘screw-in” suction cup mounting device for Window Mount or Sill Mount (See Figure 2).
2. Determine the appropriate mounting location and clean window glass or sill area
of debris or residue. Firmly press suction cup mount onto INSIDE window (glass or sill)
positioning sensor towards the OUTSIDE of window (See Figure 3).
NOTE: Thermosunis sensor MUST BE mounted indoors only and should be free from obstructions
in order to correctly sense incoming light. Sill mounts may not be suitable for some window
installations. (Sensor should be mounted in front of all interior window coverings)

SETTING THE SENSOR SENSITIVITY (THRESHOLD) - SETTING SUNLIGHT SENSITIVITY
1. Carefully remove rear cover of the Thermosunis sensor
exposing Control Setting Panel. (See Figure 4)
2. Slide the ON/OFF Selector Switch to the ON or position. Sun
LED Indicator will illuminate for 5 seconds and then extinguish.
3. Momentarily press the Mode Button and Sun LED Indicator will
illuminate for approximately 15 seconds to indicate present
threshold setting.
NOTE: LED Indicator light will remain illuminated for approximately
15 seconds. Should the LED Indicator light extinguish prior to establishing
the light sensitivity (threshold) setting, simply press the MODE BUTTON
momentarily to reactivate LED light.
4. Using a small screw driver or similar device, rotate the Sun Sensitivity Selector to the fully CLOCKWISE (+) position. LED Indicator will
remain illuminated red color (See Figure 4).
5. Slowly rotate the Sun Sensitivity Selector COUNTER CLOCKWISE (-) until the LED Indicator illuminates to a green color. A green colored
LED indicates the present light value (threshold). At this (threshold) the Sunis sensor will provide the necessary RTS command as selected
with the Function Selector Switch (for details reference pg3).
GREEN LED: INDICATES SUNLIGHT WITHIN THRESHOLD SETTING
RED LED: INDICATE SUNLIGHT BELOW THRESHOLD SETTING
NOTE: Rotating the Sun Sensitivity Selector to a FULL COUNTER CLOCKWISE (-) position will simulate sun if no sun is present. It is not
recommended to leave the selector (Threshold setting) in this position.
