The Fog / Smoke control panel is directly related to fog fixtures where ever they are selected or not.
This means that your fog machine needs to be created as a fog machine in the predefined setup of Fixture Creator.
Fixture Creator - Fog Configuration
The “Fog” button activates the fog as long as the button is held pressed.
The orange LED in front of the button indicates when the fog is on.
If you tick the “Continuous operation” check box at the bottom, this makes the “Fog” button toggle so when it is pressed fog is continuously on until it is pressed again.
In this mode the timer function is disabled.
There are two control faders: for fog intensity level and for fan speed (applicable if defined in the fixture ).
When the “Timer” button is activated, it will repeatedly activate the fog for the duration time (5 seconds in this screenshot) when the interval time (40 seconds in this screenshot) is up.
This is a function FreeStyler controls so is therefore nothing the fog machine needs to support.
The small red status bar below the interval fader shows the actual time progressing up. When the bar gets to the end, the fog is activated.
When the Timer function is on, the blue LED on the left of the button will blink.
