• the FZ-94 setup defines 2 configurations that can be switched by pressing the COMMAND/Apple key (macOS) / CONTROL key (Windows) modifer plus a number key.
  • CMD/CTR-1 (default): logs drum- and fan speed changes as custom events
  • CMD/CTR-2: defines drum- and fan speed sliders that allow to take control via a re-configuration of the frequency drives
• The drum heat limit can also be controlled via an SV slider by ticking Control in the device setup (menu Config » Device)
• The Ghibli and Silon touch setups feature control of the burner level, fan speed and drum speed which requires the roaster to be equipped with the latest firmware.
