Configuration (continued)
Daylight Regulation
Purpose:
In the presence of daylight, a luminaire is dimmed to a fixed light level on the working plane to save energy.
How to:
• When day-light based control is switched on, the light output adjusts approximately to 500 lux (this value is highly
fixture and application dependent) times the percentage value set for the Eco-on level. If the Eco-on level is set to
80% for example, the light output from the luminaire adjusts to 400 lux on desk level.
• Any time after configuration a calibration routine can be initiated. When the calibration routine is complete the
light level adjusts to the full light output (given by the operating current of the luminaire) times the percentage
value set for the Eco-on level. By adjusting the operating current of the luminaire and the Eco-on level in the App
a user has full control on the light level realized on the desk.
• Please take note of the important remarks on next page.
Remarks:
• The calibration for daylight dependent light regulation needs to be done in the absence of daylight, i.e. at night or
with blinds closed.
• When the calibration is run, the light output of the luminaires first goes to a low level and to a high level before it
regulates to the set light level. This procedure normally takes one minute but may take up to 5 minutes.
• The lux levels are an estimation for a typical office configuration; the precise level depends on the amount of light
reflecting surfaces in the field of view of the sensor. If the light level is not as wanted, please do the calibration and
adjust the light level via the Eco-on level.
• To determine the optimum Eco-on level it is recommended to turn off daylight regulation temporarily before
calibration, and to measure illuminance as a function of Eco-on level.
