Function Description

The remote controller serves as an interface for managing air conditioning units. It allows users to:

Start/Stop Operation: Initiate or terminate the air conditioner's operation with a dedicated button. A green LED lamp illuminates when the unit is operating.
Select Operation Mode: Choose from various modes including AUTO, COOL, DRY, FAN, and HEAT (HEAT mode settings are not applicable for Cooling-only models).
Adjust Airflow Direction: Set the desired airflow direction or activate a swing mode using the "LOUVER" button. Indicators show the current direction (SWING, UP, DOWN).
Control Fan Speed: Select the fan speed from options such as AUTO, QUIET, LOW, and HIGH using the "FAN" buttons. The available fan speeds may vary depending on the type of indoor unit. The AUTO option allows the system to select the fan speed automatically.
Set Room Temperature: Adjust the desired room temperature using the "TEMP." up and down buttons. The temperature setting range varies by mode:
- COOL/DRY/AUTO: 18 to 30 °C (64 to 88 °F) or 20 to 30 °C (68 to 88 °F).
- HEAT: For VRF systems, 10 to 30 °C (48 to 88 °F); for other systems, 16 to 30 °C (60 to 88 °F). The lower limit of the setting temperature can differ based on the place of use.

The remote controller also supports administrative functions, particularly in systems with multiple indoor units. If the "Priority on Administrative indoor unit" mode is set, the operating mode of other indoor units is controlled by an Administrative indoor unit. When the Administrative indoor unit is set to "AUTO", "AUTO" is displayed alongside the current operating mode on other wired remote controllers, indicating that the Administrative indoor unit controls their operation.
