Daylight sensor calibration
Daylight sensor calibration should only be done after group settings are deployed. It is important to note the environmental requirements that should be present for the calibration to result in accurate and effective Daylight Dependent Regulation (DDR):
-
Daylight sensor calibration should always be done when ambient light entering the group through windows, skylights, etc. is minimized. This means that calibration should take place at night, or when any source of ambient light can be completely blocked using blackout shades, window coverings, etc.
-
Daylight sensor calibration of a zone takes approximately six minutes. Multiple zones can be calibrated in parallel if the lights in each zone being calibrated do not influence each other (like in separate rooms with walls in between each group). If lights in different zones will influence each other during calibration (groups with multiple daylight zones or in open areas where zones from different groups must be calibrated), then the zones should be calibrated one after the other.
-
To calibrate the zone to a specific lux level setpoint, a lux meter is required to measure the light level during the calibration process which is guided by the daylight sensor calibration workflow in the app.
1 Navigate to Controls, then tap Daylight sensor calibration.
2 Tap the zone you want to calibrate.
3 Carefully read the Preparing for calibration screens, then tap Got it.
4 Adjust the default level to the required set point (here is where you will require a lux meter if the project requires DDR to target a specific lux set point), then tap Calibrate. The calibration process takes about six minutes and can run in the background. Do not control the lights during these six minutes. If you have set the hold-time to 5 minutes, make sure to trigger motion by walking by, to avoid the lights to go to background level during the calibration.
5 Tap Continue to exit.
Repeat these steps for all the zones that require Daylight Dependent Regulation in the project.
