W-2WAY ECO-i SYSTEM Outdoor Unit Maintenance Remote Controller

OUTDOOR UNIT MAINTENANCE REMOTE CONTROLLER (RCS-TM80BG) for W-2WAY ECO-i

NNAbout 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.).
