RAC 2.0 Common Option Settings
Various installation option settings are available for Samsung RAC 2.0 systems to modify system operation or to utilize
features not enabled from the factory. Installation options can be modified via the included wireless remote controller, an
optional wired controller, or with the SNET Pro 2 service software (requires the use of a MIM-C02N service tool, sold
separately). Each segment or digit within the "02" installation option code represents a separate option. There are a total
of 24 segments in the installation option code - including page numbers, but not every segment is used for every model.
Below is a general description of each segment that is used for RAC 2.0 indoor units.
Programming instructions and examples can be found on page 7 of this document
Segment 3: Auto clean
The auto clean option is used to remove moisture from the evaporator coil after the indoor unit is turned off. This setting
will operate the indoor fan for 10 to 30 minutes depending on conditions to dry the evaporator coil. This helps to prevent
the buildup of mold on the evaporator coil, thus helping to eliminate odor. The end user can cancel the Auto Clean
function while it is running by pressing and holding the "Options" button on the wireless remote for 3 or more seconds.
