REMOTE CONTROLLERS OPERATION

9.1 WIRELESS REMOTE CONTROL FUNCTION

PRECAUTIONS:

x This controls the operation of indoor unit. The range of control is 7 meters. If indoor lighting is controlled electronically, the

range of control may be shorter, in some cases; the control signal may not be received. This unit can be fixed on a wall

using the fixture provided. Before fixing it, make sure the indoor unit can be controlled from the remote controller.

x Press buttons only with fingers. Do not press buttons by any other item, as it may damage the buttons.

x Do not put the remote controller in the following places.

o In direct sunlight.

o In the vicinity of a heater.

x Handle the remote controller with care. Dropping it or getting it wet may compromise its signal transmission capability.

x After new batteries are inserted into the remote controller, the unit will initially require approximately 10 seconds responding

to commands and operating.

x Once the outdoor unit stops, it will not restart for about 3 minutes (unless we switch OFF and ON the power or unplug and

plug back the power cord again.) This is to protect the device and does not indicate a failure.

x If you press the FUNCTION selector button during operation, the device may stop for about 3 minutes for protection.

This document describes various models of wireless remote controllers for air conditioning units, including RAR-3R5, RAR-3U1, RAR-3U2, RAR-3U3, RAR-3U4, and RAR-2P2. These controllers are designed to manage the operation of indoor air conditioning units, with a typical control range of 7 meters. However, this range can be shorter if indoor lighting is electronically controlled. The units can be fixed to a wall using provided fixtures.

General Precautions and Usage Features:

Handling: Users should press buttons only with fingers to avoid damage. The remote controller should not be placed in direct sunlight or near a heater. Dropping the unit or getting it wet can compromise its signal transmission.
Restart Behavior: After new batteries are inserted, the unit may take approximately 10 seconds to respond. If the outdoor unit stops, it will not restart for about 3 minutes (unless power is cycled) to protect the device. Pressing the FUNCTION selector button during operation may also cause the device to stop for about 3 minutes for protection.
Signal Transmission: All models feature a signal emitting window/transmission sign. This window should be pointed towards the indoor unit. The transmission sign blinks when a signal is sent.
Display: The display shows the selected room temperature, current time, timer status, active function, and intensity of circulation.

Common Functions Across Models:

START/STOP Button: Initiates or stops the air conditioner operation.
TEMPERATURE Buttons: Used to raise or lower the temperature setting. Holding these buttons down will change the value more quickly.
FAN SPEED Selector: Determines the fan speed. Each press cycles through different intensity levels: AUTO, HI, MED, LOW, and EX-LOW (where applicable). This allows for optimal setting.
FUNCTION Selector Button: Selects the operating mode. Each press cycles through modes such as AUTO, HEAT, DEHUMIDIFY, COOL, and FAN.
AUTO SWING Button: Controls the angle of the horizontal air deflector, allowing it to swing continuously or be set to a desired angle.
TIME Button: Used to set and check the current time and date.
SLEEP Button: Activates the sleep timer function.
RESET Button: Should be pressed after battery replacement or if irregular operation occurs.
TIMER Control Buttons (SET TIME, TIMER Selector, ON-TIMER, OFF-TIMER, RESERVE, CANCEL): These buttons are used to set and manage various timer functions, including turn-off time, turn-on time, and time reservations. Only one timer (OFF, ON, or ON/OFF) can be active at a time.

Display: Indicates room temperature, current time, timer status, function, and circulation intensity.

RAR-3U3 (For RAS-80YH5A):

SYMMETRY SWING Button:
PARALLEL SWING Button:
Display: Indicates room temperature, current time, timer status, function, and circulation intensity.

RAR-3U4 (For RAS-WX8):

PLASMA ION Button: Activates/deactivates the plasma ion function.
EXTENDED AIRFLOW Button: Pushes air out further for an extended airflow.
- Standby Function: When the unit is in standby mode, pressing this button activates the SELF CLEANING function.
Display: Indicates room temperature, current time, timer status, function, and circulation intensity.

RAR-2P2 (For Bigflow series):

Precautions for Use: Similar general precautions as other models regarding placement (no direct sunlight, away from heaters) and handling (avoid dropping, protect from water).
Restart Behavior: Outdoor unit will not restart for about 3 minutes after stopping (unless power is cycled) for device protection. Pressing the FUNCTION selector during operation may stop the device for about 3 minutes for protection.
Display: Indicates room temperature, current time, timer status, function, and circulation intensity.

Operational Modes and Features:

Automatic Operation: The device automatically determines the mode (HEAT, COOL, or DEHUMIDIFY) based on current room temperature. The mode changes as room temperature varies.
- Setting: Press the function selector to AUTO mode, then START/STOP. Temperature can be adjusted in 1°C increments.
- Note: Preset and actual room temperatures may vary. The display does not show preset temperature in AUTO mode; a beep indicates a setting change.
Auto Restart Control: In case of power failure, operation automatically restarts with previous mode and airflow direction when power is resumed. If the circuit breaker is resumed, operation will also restart. Users should switch off power if they don't intend to continue.
Heating Operation:
- Setting: Select HEAT mode, set desired room temperature, then START/STOP.
- Note: If room temperature is higher than setting, the device dehumidifies. If lower, dehumidifying occurs at a slightly lower temperature. Function stops when room temperature falls below setting.
Cooling Operation:
- Setting: Select COOL mode, set desired FAN SPEED, set desired room temperature, then START/STOP.
Dehumidifying Operation:
- Setting: Select DEHUMIDIFY mode. FAN SPEED is automatically set to LOW and cannot be adjusted. Set desired room temperature.
Auto Changeover (Applicable to specific models and Multizone outdoor units):
- Function: Automatically changes operation mode (cooling/heating) based on outdoor and indoor temperatures.
- Criteria:
  - During Cooling: Restricted to cooling if outdoor temperature >27°C. Changes to heating if room temperature <3°C below preset.
  - During Heating: Restricted to heating if outdoor temperature <16°C. Changes to cooling if room temperature >2°C above preset.
- Temperature Thresholds: Final preset temperature is 25°C. Cooling occurs at -3°C from preset, heating at +2°C from preset.
- Applicable Models: RAC-25WX8, RAC-35WX8, RAC-50WX8, RAC-25FX8, RAC-35FX8, RAC-50FX8, RAC-25NH5, RAC-35NH5, RAC-50NH5, RAC-65NH5, RAC-25YH5, RAC-35YH5, RAC-18YH6, RAC-25YH6, RAC-35YH6, RAC-50YH6, RAC-60YH5, RAC-70YH5, RAC-80YH5.
