Release notes ACC MT Description: Air Center Control with Touch Display Software version: 2.1.0 Release date: October 2022 Hardware: 8 733 502 082 and 7 733 701 822 These release notes show an overview about the status of the software including limitations and known issues of ACC MT software version 2.1.0. Software Status --------------- Newly added features: - Modbus/RTU energy meters visible on system monitor - Energy meters can be assigned to ODUs - Energy distribution for AF5300 systems - System-based hourly/daily/monthly energy-distribution report in Excel format - Tenant management (tenants can be created and IDUs assigned) Removed features: - 12-hour time format Improvements: - Several bugs fixed - Security patches - Faster XYE communication after scanning 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. - This software can only be installed on ACC already executing 0.3 or higher. 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. 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. Energy distribution: - In case of a broken Modbus/RTU connection to a energy meter, the energy distribution report may need manual correction. - In case of serious issues of longer than one hour within the first week, there may be no data in the energy distribution report for that time frame. - In case ACC is not powered-on at 00:10, the daily summary of the last day may not be calculated. This can be still calculated manually based-on hourly data. - In case ACC is not powered-on on the first day of a month at 00:20, the summary of the last month may not be calculated. This can be still calculated manually based-on daily data.
