6-1. Overview
What is the outdoor unit maintenance remote controller?
Beginning with the DC-INV series of outdoor units, nonvolatile memory (EEPROM)
is used in the outdoor unit PCB. In this way, the setting switches that were located
on earlier PCBs have been converted to EEPROM data. This remote controller is an
outdoor unit maintenance tool that is used to make and change the EEPROM set-
tings.
This remote controller can be used for checking the outdoor unit EEPROM settings
and contents, and also can be used to monitor the outdoor unit alarm history and
indoor/outdoor unit temperatures, and to check the status of the indoor unit connec-
tions (No. of units, operating status, etc.).
Note: Because this tool does not function as a remote controller, it is used only dur-
ing test runs and servicing.
* The special service checker wiring is required in order to connect the outdoor unit maintenance remote controller to
the outdoor unit PCB.
* Even when the outdoor unit maintenance remote controller is connected, a separate remote controller or other con-
trol device must be connected to the indoor unit.
