Unison Echo Light SensorETC
Echo Control Series
GENERAL INFORMATION
Having the lights on in an already well-lit area means wasted energy
and bigger electrical bills. Echo Light Sensors are the sensible way
to lower energy expenditures and meet energy codes. Light Sensors
have a neutral look that easily blends into their surroundings. The
sensors are ready to go in their standard form, or you can detach
the sensor’s RemoLux head to use as a remote sensor. It is perfect
for atriums and other spaces with high ceilings. The Light Sensor can
also be installed indoors or outdoors.
