Operating Modes
The Operating Modes screen provides Unit and Circuit level mode information valuable to
understanding the equipment operating state. Each Unit and Circuit mode provide sub-mode
information with details to understand active controls and limits that are affecting operation especially when there are NOT any active Alarms present.
Important Note:
RAUK – if your unit does not have a physical TD7 display, a virtual TD7 display can be accessed by connecting your laptop to the Symbio controller with a USB-A to USB-B connector (printer cable). Open Chrome, Firefox or Microsoft Edge web browser and type in http://198.80.18.1/UI_Medium/index.html in the address field. This will be necessary as RAUK units ship in the Stop mode by default.
Unit Operating Modes
Unit operating modes provide a status of the equipment operating state. Each of the unit modes will
have one or more sub-modes that provide more details about the functions active in the mode. The
following tables show each top level mode and list the possible sub modes for each, associated with unit
and refrigeration circuit operation.
Circuit Operating Modes
Circuit Operating Modes provide refrigerant circuit level operating state and sub-mode information.
When the unit has two circuits, the user interface will provide both Circuit 1 and Circuit 2 mode and submode
information. The tables below show each Circuit - Top Level Mode and lists the Sub Modes
possible.
