Object_Name
The name of the parameter with the name of the Room Light Control as a prefix.
Object_Type
ANALOG VALUE (2).
Present_Value
The value of the parameter.
Value
The light intensity in percentages for the Room Light Control.
Same value as the property Present_Value of the associated Loop object.
Controlled_Variable_Value
The current value of the light sensor.
Same value as the property Controlled_Variable_Value of the associated Loop object.
Setpoint
The value of the current setpoint in luxe.
Same value as the property Setpoint of the associated Loop object.
Hold_Time
The hold time in seconds used for the occupancy state. The occupancy state remains in the occupied state for the hold time when the value of Occupancy_Variable_Value changes to be unoccupied.
Valid values are between 0 and 2 400 seconds (40 minutes) with an interval of 10 seconds.
Same value as the property Hold_Time of the associated Loop object.
Ignore_Time
The ignore time in seconds used for the occupancy state. Once the occupancy state changes to unoccupied the ignore time is used to temporarily ignore the occupied change of the Occupancy_Variable_Value.
Valid values are between 0 and 2 400 seconds (40 minutes) with an interval of 10 seconds.
Same value as the property Ignore_Time of the associated Loop object.
Occupied_Level
The output light intensity when entering the occupied state.
Same value as the property Occupied_Level of the associated Loop object.
Unoccupied_Level
The output light intensity when entering the unoccupied state.
Same value as the property Unoccupied_Level of the associated Loop object.
Step_Value
The maximum value in percent that the Room Light Control can change its output per second, during constant light control.
Valid values are between 0 and 100 % with an interval of 0.5 %.
Same value as the property Step_Value of the associated Loop object.
Lamp_2_Offset
The offset between the primary and the secondary output.
Valid values are between 0 and 100 % with an interval of 0.5 %.
Same value as the property Lamp_2_Offset of the associated Loop object.
Lamp_2_Limit
The value where the secondary output becomes the same as the primary output.
Valid values are between 0 and 100 % with an interval of 0.5 %.
Same value as the property Lamp_2_Limit of the associated Loop object.
Override
The value of the output override in percent (0 - 100%). When the value is NaN the override is disabled.
Same value as the property Override of the associated Loop object.
Setpoint_Occupied
The setpoint of desired light illuminance of the room when the occupancy state is occupied.
Valid values are between 0 and 65 534 lux with an interval of 1 lux.
Same value as the property Setpoint_Occupied of the associated Loop object.
Setpoint_Unoccupied
The setpoint of desired light illuminance of the room when the occupancy state is unoccupied. It is also possible to use a relative setpoint to the Setpoint_Occupied, for this a negative is used that will represent a percentage to reduce from the Setpoint_Occupied.
Valid values are between 0 and 65 534 lux with an interval of 1 lux. When relative setpoint is used the valid values are between -100 and 0 % with an interval of 1 %.
Same value as the property Setpoint_Unoccupied of the associated Loop object.
Deadband_Setpoint
The dead band in luxe used by the current setpoint.
Valid values are between 0 and 65 534 lux with an interval of 1 lux.
Same value as the property Deadband_Setpoint of the associated Loop object.
Warning_Time
The warning time in seconds used for the occupancy state. The Warning_Command is executed before the Unoccupied_Command which is executed after the Warning_Time, when the value of Occupancy_Variable_Value changes to be unoccupied.
Valid values are between 0 and 2 400 seconds (40 minutes) with an interval of 10 seconds.
Same value as the property Warning_Time of the associated Loop object.
Warning_Command_Value, Occupied_Command_Value, Unoccupied_Command_Value
| Name | Value Range | Unit |
|---|---|---|
| Disabled | 0 | |
| Direct Value | 0 - 100 | Percent |
| Max Level | ||
| Off | ||
| Min Level | ||
| Recall Scene | 0 - 15 | Scene number |
| Start Daylight Harvesting | ||
| Stop Daylight Harvesting | ||
| Relinquish |
Same value as the property Warning_Command_Value, Occupied_Command_Value or Unoccupied_Command_Value of the associated Loop object.
Minimum_Intensity
Minimum intensity of the Room Light Control output.
Valid values are between 0 and 100 % with an interval of 0.5 %.
Same value as the property Minimum_Intensity of the associated Loop object.
Maximum_Intensity
Maximum intensity of the Room Light Control output.
Valid values are between 0 and 100 % with an interval of 0.5 %.
Same value as the property Maximum_Intensity of the associated Loop object.
Override_Timeout
The override timeout in seconds used when unoccupied. The override remains active for this time, before returning to the unoccupied state.
Valid values are between 0 and 72 000 seconds (20 hours) with an interval of 300 seconds.
Same value as the property Override_Timeout of the associated Loop object.
Demand_Response_Value
The demand response allows limiting the illuminance of the room. A negative value reduces the illuminance of the room by this value in percentages. A positive value increases the illuminance of the room by this value in percentages. When daylight harvesting is active, the setpoint is decreased or increased by this value in percentages.
Valid values are between -100 and 100 percent with an interval of 1 percent.
Same value as the property Demand_Response_Value of the associated Loop object.
Description
A description of the object.
Status_Flags
This property indicates the general "reliability" of the object.
Reliability
This property indicates whether the operation of the object is reliable. The values are as follows:
- NO_FAULT_DETECTED (0) - No fault has been detected.
Out_Of_Service
It indicates whether the algorithm that the object represents is in service.
