auto-diagnostic system for rapid fault finding (see section: “Error messages”)
• Language selection
• Alphanumeric text display
• Internal log memory with 1024 kB for storing actual temperature, temperature setpoint, vacuum and
error states with time stamp
• Control of oven and logging of actual temperature values on MEMoryCard XL
• Programme sequence control for up to 40 ramp segments
• Vacuum pressure control for digital operation of the built-in solenoid valves
• Programmable inlet valves for fresh air and inert gas
• Integrated weekly programmer with group function (e.g. all workdays)
• Recessing push/turn control for simple operation of the oven
• Visual alarm indication
• Built-in sounder as alarm if limit values are crossed, as acoustic signal at programme end and to
acknowledge input (key click)
