How to Use
Upload a .dat file on the Central Controller Config Tools page, then click Group Rearranger to open it here. Drag and drop group cards into the numbered slot positions. Slot numbers stay fixed — groups are automatically renumbered when dropped. Double-click a group tag name to edit it inline, and click the controller name above the grid to rename it. If the file has refrigerant systems, tick Create blocks from refrigerant systems to get one block per outdoor unit. Download the rearranged configuration when finished.
