2. Press ON for 3 seconds. If the dimming output is enabled the light will turn ON, if
disabled the light will be OFF
3. Click ON to activate this function, OFF to deactivate.
4. To continue with configuration, press ON for 3 seconds, the light will resume
dimming down + up seven times. To exit Smart Click press OFF for 5 seconds.
Level 8 - Lighting Set point -
The set point is a single value that can affect how the
controller manages the light output depending on if the controller is setup for daylight
harvesting or photo inhibit applications.
When set for photo inhibit operation, the Auto-ON feature associated with a linked
occupancy sensor will be ignored when the natural light level measured by the light
sensor is above the lighting set point. The photo inhibit feature will not turn lights OFF if
the lights are ON.
Photo Inhibit Examples:
• Light level is < day-lighting set point – The lights do turn ON automatically when
you enter the room.
• Light level is > day-lighting set point – The lights do not turn ON automatically
when you enter the room.
• Lights are ON and the light level increases past day-lighting set point – The lights
stay ON.
• Lights are OFF and the light level decreases past day-lighting set point – The lights
will turn ON upon the next motion detected by the occupancy sensor.
When set for daylight harvesting operation, the set-point is
used with a photo sensor
(light sensor) and will automatically turn lights on and off or modulate dimming fixtures
depending on ambient light levels.
You can use the light sensor to function as a closed loop sensor. When set as a closed
loop sensor, the controller will dim the lights until the light level recorded at the sensor
meets the set-point value. For more information on this operating mode, see the section
at the beginning of this guide titled Daylight Harvesting Application.
If the light from the fixture does not impact the light reading at the sensor then it is
an open loop application. When the dimming output is enabled, the value selected
becomes the maximum dimming set point. With the dimming output disabled, the value
becomes the Light-ON set point.
Control Response
In the diagram below, the thick line indicates the dimming output. The output will
begin lowering as the natural light level increases (thin line). The point where the light
output begins dimming down is the lighting set point (default 60% sensor FSR). The
minimum dimming level is set to 100% sensor FSR.
To adjust the light set-point:
• Enter Smart Click configuration mode and click the switch ON or OFF until the light is
dimming down + up eight times.
