Limitations / known issues
--------------------------
General:
- To be able to select a country not yet existent in the pre-installed software version,
  this version must be already installed first. A factory reset is required after a
  software update to reach the installation wizard again to select the country.

Group editor:
- Although written differently in the manual, the group editor can only be access by an
  "Administrator" user.

IDU listings:
- Scrolling with a long list of IDUs: Use either scroll bar, or touch the white area left
  of the check boxes or right of the rename icon to scroll instead of drag-n-drop.

Time and date settings:
- 12-hour time format is only working for visualization of current time within dashboard
  and footer. All other functions are 24-hour time format only.
  Suggestion: Only use 24-hour time format.

Fault and event history
- In rare cases, already solved errors on IDU side still show as pending error within the
  fault and event history. If this is the case, please clear the fault and event history.

MDCI:
- General system limitation
  - Dry mode can be enabled on all controls (ACC MT, ARC and IRC) for IDUs connected to
    MDCI systems, but response to ACC MT is always cooling mode. This means, after some
	seconds, ACC MT will show cooling mode instead of dry mode.
  - Only mode and IRC lock are possible, although others like ARC lock are now offered by
    the ACC MT, those locks are non-functional in MDCI systems.
  - IDUs which are in mode conflict are shown as "off" on ACC MT.
  - ACC MT shows always the default icon "4-way cassette IDU", independent from the real
    IDU type.
  - The current outdoor temperature display is not available.
  - System structure: No outdoor unit information available.
  - System monitor: No diagnosis data available for MDCI systems.
- Limitations depending on ODU firmware
  - Although the ACC offers seven fan speeds, those may be mapped to three fan speeds
    in case the ODU executes an old firmware (update not possible). Use of seven fan
	speeds via the ARC and IRC still possible.
