Settings

Parameters
- Latching Time: Time distinguishing between short and long-click of a pushbutton.
- Toggle Mode: If you use the Toggle Mode via "On / Off command of the functional unit", the lamp / lamp group toggles between the resetting value and "off".
- Dimm Up Option: This describes what the assigned lamp (group) will do, if a short-click of Digital Signal (Group) - Dimm Up was detected.
- Dimm Down Option: This describes what the assigned lamp (group) will do, if a short-click of Digital Signal (Group) - Dimm Down was detected.
Sensors / Actuators

In this menu you enter the lamp / lamp group and the digital signals for switching the correspondent lamp / lamp group.
In general there are two different procedures to control the lamp / lamp group: with two pushbuttons for dimming up and down or with one pushbutton which alternately dims up and down. A combination of both procedures is possible.

Commands
- Fade Up: This command will increase the light value of all assigned lamps by their entered fade-rate. The command will only work when the lamp is already turned on. Increasing the value above the maximum level is not possible.
- Fade Down: This command decreases the light value by the entered fade-rate but will not let a lamp turn off completely.
- On: Turns the assigned lamps either to the maximum or the Resetting Value, which depends on the fact, if the Resetting Mode is activated or not. The Resetting Mode can be activated for each lamp separately.
- Off: Turns the assigned lamps off. When the Resetting Mode is activated the light value prior to the off state will be stored.
- Call Maximum Control Value: Each lamp will be turned to its maximum level.
- Call Minimum Control Value: Each lamp will be turned to its minimum level.
- Off ↔ Resetting Value: The switching direction depends on the average value of the lamp (group). If the value is greater than 0 all lamps will be turned off. When the value is equal to 0 all lamps will be either turned to their Resetting Value or to their maximum value, when the Resetting Mode is not activated at the lamp.
- Off ↔ Max Control Value: The same as Off ↔ Resetting Value but all lamps will be toggled between off and their maximum value.
- Set Control Value Direct: The entered value will be taken over to the lamps, when the Apply-button is pressed. If the entered value is greater than the maximum value of one of the lamps, the lamp will be set to its maximum level. If it is lower than its minimum level, but not 0, the lamp will be set to its minimum level. Entering and applying 0 will turn the lamps off.
State
- Average Control Value: Average value of all active (non-erroneous) lamps.
- Resetting Value: When the functional unit is turned off, the previous light level will be stored in this variable. If you have selected the entry "Toggle via On/Off command of the Functional Unit" as "Toggle Mode", the lamps in the functional unit are set to this value, when they are switched on with the command Off ↔ Resetting Value and the Resetting Mode of the lamp is deactivated.
