Adjust Daylight Dimming Response*
Out-of-the-box, the daylight sensor is operational for basic operation to automatically control dimmers 1, 2 and 3. Adjustments to default light levels
are done using the Daylight Sensor Programming Remote HHPRG-RC. The remote control contains Zone Level buttons, 1, 2 and 3, which correspond
to dimmers 1, 2 and 3 on the Room Controller. Zone 1 should be the zone closest to the window, while zone 3 is furthest into the space.
When the remote is used to adjust light levels, within the daylight sensor’s lens, the Red LED
should flash each time the button is pressed. The Green LED will flash rapidly indicating that
the Room Controller has entered Commissioning Mode.
LED Location
Daylight Sensor
Daylight levels are being set during the day when lighting should be dimming from daylight contribution, but not to the point where loads
should be at a full dim level.
Press any wallstation “All OFF” button and then turn lighting ON again. Immediately after, verify that the Green LED in the daylight sensor
lens is not on. If it is on, please follow the procedures on page 18 to change the sensor range and reset daylight levels.
Point the remote at the daylight sensor lens and press the raise or lower button for the appropriate zone until the desired light level is
reached.
Repeat this process for each of the dimming zones as needed.
To save the new levels and exit Commissioning Mode, press the “All OFF” button on any wallstation. If “All OFF” is not pressed, the
controller will save the settings and exit Commissioning Mode after two minutes.
The setup process is now complete.
*Some daylighting sites may require a more in-depth setup process due to sensor location or furnishings in the space. If
daylighting does not appear to be operating after following this basic procedure, refer to the next section to make Advanced
Daylight level adjustments.
Advanced Daylight Level Adjustments
For more in-depth adjustments in rooms where daylighting does not seem to operate as intended with the basic daylight
setup performed, OR, if the Green LED seems to be on within your daylight sensor lens, follow the procedures below.
Daylight Levels should not be set at night or when the space is overly saturated with natural light. The daylight levels should
be set during a time when loads should be dimming from the daylight contribution, but not to the point where the load
should be at a full dim level.
Verify and Set the Daylight Sensor Range
The daylight sensor provided has three ranges of operation. The default level is the High Range of 30-3000 lux
(approx. 3-280 FC), which will operate properly for most applications. The first step in this process will be to verify the current
sensor range is adequate for the light level being sensed by the sensor.
If the sensor is reading too much light for its current range setting, it will flash its Green LED with a slow blink pattern
(6 seconds ON, 1 second OFF, repeated)--this blink pattern may appear as if the Green LED is continuously on. Adjust the
range if you see this behavior.
