The central controller is used for centralized management of indoor units (up to 64 indoor units can be connected via an adapter card).
The indoor units can be divided into 20 zones, each zone can contain no more than 64 indoor units. All indoor units in one zone can only be set to the same mode. (By default, "the zone is not assigned to indoor units").
Users can select the desired mode and temperature with a weekly schedule. Control can be a separate internal unit, a zone or all indoor units.
The controller displays the error codes and the current operating status of the connected indoor units.
