Window covering does not
react to Thermosunis sensor
Window covering moves
too frequently
Window covering reacts
incorrectly
The Sensor Selector Switch is in the “OFF” position
The Sensor is not programmed to the motor or RTS receiver.
The sunlight sensitivity (threshold) is incorrectly set.
The temperature sensitivity (threshold) is incorrectly set.
The battery is low/weak and needs replacing.
The Sensor cover is dirty or obstructed.
The Sensor is incorrectly positioned/mounted.
Window covering may have received a subsequent
command from another RTS control (i.e., Telis
transmitter, Chronis timer, Decoflex wall switch.)
The Sensor is in “demo” mode.
The sunlight/temperature sensitivity (thresholds)
may need to be adjusted.
A bright light source may be affecting the sensor.
The motorized window covering (directional output)
is programmed incorrectly (in-reverse).
Switch the Sensor Selector Switch to the Sun or Sun/Temp
position
Reference ”Programming: Initial Installation instructions”.
Increase the sun sensitivity (threshold) selector to
“less sun” (-) position.
Re-adjust the temperature sensitivity (threshold) accordingly
Replace battery with correct rated/type.
Clean cover and check for any obstructions.
Reposition Sensor to a more suitable location
Manually command the window covering to its intended
position using another RTS control (i.e., Telis transmitter, Chronis
timer, or DecoFlex wall switch.) Sensor will eventually cycle to
its initial mode.
Switch sensor to standard (default) mode, or wait 2 minutes.
Sensor will automatically default to standard mode
Adjust Sun & Temperature sensitivity selector accordingly
Inspect sensor and surroundings for errant light source.
Confirm correct directional output of window covering via
Telis transmitter or similar device. Program necessary
corrections.
