Sensor Calibration and Sensitivity

Ambient Light Calibration

Redwood Sensors are shipped calibrated, except for the ambient light Sensor. The ambient light

Sensor has an adjustable dynamic range. You must calibrate it based on the light level of the

space. (Calibration might not be needed if you are not using the daylight harvesting feature.)

IMPORTANT NOTE

Note that not calibrating only prevents the daylight harvesting feature from working, so

calibration may not be needed in all installations. Stored light Sensor readings may also be

affected.

Before beginning calibration, do the following:

! To set up for calibration, it is recommended that you finish all other aspects of commissioning.

! Turn on all non-Redwood-controlled lights that would usually be on, such as emergency

lights.

! Set all Redwood-controlled lights to their normal Policy when daylight harvesting is running.

! Perform calibration when it is dark outside and there is no significant external light.

! Determine if a Fixture has already been calibrated by checking its status in the Maintenance

tab.
