Lighting control overview
EasySense controls the light output based on the
occupancy, daylight regulation and field task level.
When both occupancy- and daylight-based lighting
control are enabled, the light level is determined by
the lowest light level of the following:
• Occupancy-based set point (either the switch-on
level, background level or off)
• Daylight regulation set point (The daylight
regulation set point is the amount of light needed
on top of the available daylight.)
• Field task level
In case occupancy-based lighting control is disabled,
the occupancy-based set point is not used for
determination of the light level. In case daylight-
based lighting control is disabled, the daylight
regulation set point is not used for determination of
the light level. When both occupancy-based light
control and daylight-based light control are
disabled, the light output will continuously be on
field task level.
