Operating principle
This product is mainly intended for automatic
control of inside/outside lighting circuits (ON/
OFF and dimming controls) and blinds or rolling
shutters according to ambient lighting level.
Associated with an external probe, this light-
sensitive switch measures natural lighting and
controls circuits according to a preset threshold
range of 2 to 20000 lux.
Several light sensitive switches may be chained to
increase the number of channels.
In this case, only one probe is connected to one of
the light sensitive switches.
Setting lighting threshold
After configuration :
1. Set switch 1 to the test position (threshold
2. Press push-button 6 (one of indicators 2 or
3 lights on) to select the gauge (2... 200 lux or
200... 20000 lux).
3. Switch back auto/manu/test switch to the
desired mode
4. Set switch 1 to "test" position; at the
selected moment of the day, turn the setting
potentiometer 4 up to the switching threshold
(indicator light 5 switches on).
5. Set back switch 1 into "auto" position, as the
normal operating mode of equipment.

Installation recommendations
1. Install the module at the bottom of enclosure to
prevent excessive operating temperature.
2. Connect module to bus.
3. Connect probe EE002 or EE003 if necessary.
4. Follow the instructions of system requirements.
5. To ensure a good working of the light
sensitive switch, the lighting probe must not
be influenced by artificial light or direct solar

Indicator light goes on when the value measured is lower
than threshold set.
Indicator 2 is on when gauge 2 ... 200 lux is selected.
Indicator 3 is on when gauge 200 ... 20000 lux is selected.
Indicators 2 and 3 flicker alternately when probe is not
connected or faulty.
