■ About the outdoor unit maintenance remote controller
The outdoor unit utilizes nonvolatile memory (EEPROM) on
its PCB. This allows EEPROM data to replace the setting
switches that were present on previous PCBs. The outdoor
unit maintenance remote controller is used to set and change
these EEPROM data.
In addition to setting and checking the outdoor unit EEPROM
data, this remote controller can also be used to monitor the
outdoor unit alarm history, monitor the various indoor and
outdoor temperatures, and check the indoor unit connection
status (number of units, operating mode, etc.).
NOTE
Outdoor unit maintenance remote controller does not function as an
ordinary remote controller. It is therefore only used for test runs and during servicing.
