Operating Mode
Description
REGULATOR (1)
A light sensor that measures the indoor illumination is
installed.
An occupancy sensor is installed.
CONTROL (2)
A light sensor that measures the outdoor illumination is
installed.
An occupancy sensor is installed.
UPDATER (3)
A DALI sensor with constant light controller functionality
shall be mapped to the BACnet network. Only the setpoint
shall be adjustable via the BACnet interface.
PRESENCE (4)
Based on occupancy the lights shall be switched on and off.
REGULATOR_NO_OCC (5)
A light sensor that measures the indoor illumination is
installed.
No occupancy sensor is installed.
CONTROL_NO_OCC (6)
A light sensor that measures the outdoor illumination is
installed.
No occupancy sensor is installed.
MANUAL_ON_AUTO_OFF (7)
Lights are switched on manually, but shall be switched off
based on occupancy.
REGULATOR_AUTO (8)
Similar to REGULATOR, but a manual override is
automatically relinquished when the room becomes
unoccupied.
CONTROL_AUTO (9)
Similar to CONTROL, but a manual override is
automatically relinquished when the room becomes
unoccupied.
PRESENCE_AUTO (10)
Similar to PRESENCE, but a manual override is
automatically relinquished when the room becomes
unoccupied.
AMBIENT (11)
Effect or ambient lighting is switched on based on the
measured illumination level (switching on ambient lights
does not influence measured illumination level).
REGULATOR_BEDROOM (12)
Similar to REGULATOR_AUTO, but a manual override is
not automatically relinquished when the lights are
overridden to off.
CONTROL_BEDROOM (13)
Similar to CONTROL_AUTO, but a manual override is not
automatically relinquished when the lights are overridden
to off.
Table 38: Constant Light Controller Operation Modes
Regulator Mode
The REGULATOR mode has to be selected if the installed light sensor measures the indoor
brightness. The constant light controller receives the current indoor lux level via the
property
Controlled_Variable_Value
and adjusts the lamp level (from 0% to 100%) by
means of a fuzzy control algorithm.
When the light is switched on the control algorithm selects a lamp value which results in a
lux level close to the desired setpoint and then adjusts the lamp value in increments once
every second until the configured setpoint is reached. The size of increments is adjusted
dynamically but will never exceed the percentage value defined in the proprietary property
Step_Value
(property ID 544).
The regulator mode is available in different flavors:
With our without occupancy sensor
: If an occupancy sensor is installed and the room
becomes unoccupied, the current light level is saved and the light is dimmed to
