Load from file	Allows loading a binary setting file in the interface.
Save to file	Saves the setting in a binary file.
Read	Read the current setting of the dimming controller.
Write	Write the setting in the dimming controller.
Config Version	Indicates the version of the setting.
Foot-candle to Lux	Displays a window to convert a value of foot-candle to lux and vice versa.

Status

This window provides access to the status of the dimming controller.

Item	Explanation
Input	The entry value is calculated in lux or percent depending on setting.
Digital Input 1	Value of the digital input 1.
Digital Input 2	Value of the digital input 2.
Digital Input 3	Value of the digital input 3.
Input 0-10V	Value of the 0-10V physical input.
Output	Last command sent to the relay. Output percentage: if shown in red, the output feedback is not following the output command. Value of the 0-10V physical input as 0% and 100% can be limited by settings.
Occupancy	Occupied mode.
Setpoint	Setpoint for occupied mode.
Setpoint unoccupied	Set point of the unoccupied mode.
Burn-In Duration	Remaining time (in hours) for initial lamp burn-in. Writing a value greater than zero starts the burn-in and the value will decrease by one each hour. While the burn-in is active, dimming commands are prohibited.
Run Hour	Indicates the total time (in hours) the output has a value greater than 0%. The button "Reset" writes zero to this value to clear accumulated times.
Unoccupied Delay	Delay (in seconds) before the Occupancy takes into account the changes to the input. For example, this value may adjust the time of a motion sensor. It must then be set to minimum as sensor delay is added to this delay.
BACnet Output Command Dim Mode	Determines if the BACnet command uses the fade or not.
Overwrite	This section allows direct modification of some values.
Output 0-10V	Percentage of the 0-10V output.
Occupancy	Occupancy mode.
