WireFree Eolis Sensor – Preliminary

Part #9013911

I. The Somfy WireFree Eolis sensor (Figure 1) is a battery powered, 2-axis,

vibration sensor that detects vibration of an awning caused by excessive
wind. Upon detecting excessive vibration, the sensor emits an RF signal
to retract the awning. The sensor is bound to an RTS motor as if it were a
Telis transmitter. The sensor is housed in a weather resistant enclosure.

II. Preliminary specifications:

a. Size: 45 mm X 100 mm X 32 mm
b. Lithium Battery Powered, minimum 7-year life. Assumes 50 “Wind

Present” transmissions per day.

c. Range: 50’ open air

III. Mounting considerations: With the awning extended, the sensor must

be mounted either horizontally or vertically; not on an angle. Either end of
the front bar is the preferred mounting location with the awning arms being
a secondary possibility. For proper operation, the awning should be rigidly
mounted to avoid excessive vibration.

a. Horizontally: When mounting horizontally (Sensor A parallel to the

ground) Adjust set point A to setting F and set point B to setting 0.

b. Vertically: When mounting vertically (Sensor B parallel to the

ground) Adjust set point A to setting 0 and set point B to setting F.

IV. Binding Sensor to Motor – Prior to mounting:

a. Set both set points 0
b. Set DIP switches as shown in Figure 2 – Set Up

c. Insert battery
d. Put RTS motor in program mode by depressing the program button

on original transmitter. Motor jogs.

e. Push the program button on the sensor. Motor jogs. The sensor is

now bound to the motor.
f. Set the DIP switches to Run as shown in Figure 3.
g. To test: Depress the program button and verify that the awning

retracts.

V. Mounting: Adjust the set points as described in I. above. Install cover.

Once the location is chosen mount the sensor using self-tapping sheet
metal screws. While mounting the sensor, be certain to have the original
transmitter nearby, as the sensor will most likely send an up command
due to handling.

VI. Operation:

a. There must be two vibration events exceeding the threshold within

15 seconds for the sensor to send an UP command.
b. There is a delay of 4 seconds between the first vibration event and

the sensing of the second vibration event. This is needed to prevent

nuisance trips caused by the awning arms releasing upon start-up

and the awning stopping upon reaching the extended limit.
c. If the awning is fully retracted and a down command is sent, a

subsequent stop or up command sent within 15 seconds will likely

cause the sensor to send an up command.
d. If the awning is started and stopped within 15 seconds from any

position, the sensor will likely send an up command.
e. The sensor requires 10 seconds of calm before it will send a

second signal. This delay prolongs battery life.
f. When the battery is near full discharge, the sensor will send an up

command and shut down.
