Setting the set point is covered later in this document under “Configuring the Controller”.
The daylight harvesting application can override the Auto-ON feature of occupancy
sensors if the light level is sufficient and calls for the lights to be off.
The daylight harvesting application can be overridden by a manual wall switch when the
light is dimmed to off by clicking the switch on. If the light level remains above the Light-
OFF-Set point, the controller will turn the light off again after 250 seconds.
The daylight harvesting application does not affect the operation of the wall switch or
motion sensor when the light is on. If the light is on, either the switch or motion sensor
can override the light off.
See the section on Occupancy Based Lighting Application - Photo Inhibit for alternative
functionality.
Radio Range Confirmation
The “F series” controllers includes patent pending technology that works with all
Echoflex sensors equipped with the range confirmation feature to provide visual
feedback of a linked sensors signal strength for optimal sensor placement.
To evaluate the radio signal strength, the sensor must be also support the test and be
linked to the controller. Check the sensors documentation to find out if it supports radio
range confirmation testing. Do not have any repeaters in the controllers vicinity enabled
during the test.
The range confirmation test is invoked at the sensor and sends unique telegrams to the
controller. The controller will evaluate the signal strength from the sensor and send back
a unique telegram containing the strongest signal value received. This value is displayed
at the sensor using color LEDs.
Consult the sensor installation guide for more details.
