Many of them will be solved with the next SW release, so the SW on the ACC MT should be updated then. General Issues: - ACC MT might show a white screen and does not respond to any user inputs in some rare and not reproducible cases. Resolution: Restart the ACC MT. The ACC MT can be restarted by using the restart button on the left side (next to the USB port) or by plug out and plug in of the power supply. - For indoor units connected to the same wired remote controller (ARC C) and if the system was scanned on an ACC MT with an older software version: The indoor units which are connected to a single ARC C might be shown wrongly on the ACC MT. Resolution: Rescan the VRF system on the ACC MT. Scan VRF systems: - The scan result might be displayed incorrectly which means the scan is displayed as "failed" although scan was successful. Resolution: If scan is displayed as "failed", log out and log in again and access system structure to check scan result manually. If scan was not successful, check VRF system status for other possible reasons and restart ACC MT to retry the scan. - The scan result might not show all connected refrigerant systems. Resolution: If scan was not successful, check VRF system status for other possible reasons and restart ACC MT to retry the scan. - The scan process takes longer than expected (approx. 5 min) and the progress indicator disappears without success or fail notification. Resolution: Log out and log in again and check the scan result manually. If scan was not successful, restart ACC MT to retry the scan. Schedules: - Rename a schedule. It is not possible to rename an existing schedule. Resolution: Delete the schedule and create a new one using the new name. - Schedule execution while an indoor unit is offline, which is assigned to the schedule. In this scenario the execution of the schedules fails, if any indoor unit which is assigned to the schedule is not reachable by the ACC MT. Furthermore, the settings defined in the schedules are not applied to any indoor unit. - Overlapping schedules: If a schedule is already enabled it is not possible to create a second schedule with overlapping periods and assign IDUs to the second schedule. Time and date settings: - After setting time and date, the ACC MT might log out the current user session. Resolution: Log in again after setting time and date. Error manager: - In the event and fault history it is possible to sort the events and faults with an ascending or descending order for different categories by clicking on the column heads. This sorting function is working only once. Resolution: access the event and fault history again to sort the list again with the preferred order. Floorplan-View: - In rare scenarios, the indoor units displayed on a floorplan view might vanish if settings are changed on the ACC MT. Resolution: Log out the current user, log in again, and access the floorplan view again. Lock Manager: - For Mini-VRF systems: If mode lock settings are applied to more than four IDUs at the same time, the mode lock settings might not be applied to all IDUs. Resolution: Do mode lock settings with single IDUs selected. System monitor: - The tab "Outdoor unit" might not show all available parameters. XYE Extension kit (AC-XYE): - The ACC MT might show a communication error. Operating IDUs is still possible. Resolution: Restart AC-XYE and ACC MT.
