This document is an operation manual for the Daikin Wireless Remote Controller Kit, covering models BRC7EA628, BRC7EA629, BRC7EA630, BRC7EA631, and BRC7EA632. It provides instructions for safe handling, operation, and troubleshooting of the remote controller and its interaction with the air conditioning system.
Function Description
The Daikin Wireless Remote Controller Kit is designed to operate Daikin air conditioning units, including VRV and Sky Air Systems. It allows users to control various aspects of the air conditioner's operation, such as power ON/OFF, operation mode selection (Cooling, Heating, Automatic, Fan, Dry), temperature setting, fan speed control, air flow direction adjustment, and programming of timer functions. The remote controller transmits signals to a receiver on the indoor unit, with a transmitting distance of approximately 7 meters.
Important Technical Specifications
- Models Covered: BRC7EA628, BRC7EA629, BRC7EA630, BRC7EA631, BRC7EA632.
- Power Source: Two AAA.LR03 (alkaline) dry cell batteries.
- Temperature Setting Range: 16°C to 32°C.
- Timer Programming: Up to 72 hours for both start and stop times.
- Fan Speed Options:
- BRC7EA628/629: High/Low.
- BRC7EA630/631/632: High/Medium/Low.
- Control Systems: Supports individual control, group control (one remote controller for up to 16 indoor units), and two remote controllers control system (two remote controllers for one indoor unit or one group of indoor units). Note that the two remote controller system with only wireless remote controllers is not supported.
- Refrigerant: The manual warns about refrigerant leakage and the generation of noxious gas if it comes into contact with naked flames. The refrigerant itself is safe and normally does not leak.
- Safety Features: Includes a safety device that prevents overload, causing a 5-minute delay before restarting operation.
Usage Features
The remote controller features a clear display and intuitive buttons for various functions:
- ON/OFF Button (8): Starts or stops the system.
- Temperature Setting Buttons (10): Adjusts the set temperature. Operates with the front cover closed.
- Operation Mode Selector Button (15): Selects between Cooling, Heating, Automatic, Fan, and Dry modes. Automatic operation is available only for Heat pump split or Heat recovery VRV systems. For cooling-only types, only Cooling, Fan, and Dry operations are available.
- Fan Speed Control Button (9): Selects desired fan speed (High/Low or High/Medium/Low depending on the model). The microchip may automatically control fan speed to protect the unit.
- Air Flow Direction Adjust Button (14): Controls the air flow flap. Allows for continuous automatic swing or fixed air flow direction. Left/right air flow direction can be adjusted manually via a knob on the unit.
- Programming Timer Button (11): Used to set "START and/or STOP" times. Operates with the front cover opened.
- Timer Mode Start/Stop Button (12): Selects timer mode.
- Timer Reserve/Cancel Button (13): Confirms or cancels timer settings.
- Inspection/Test Operation Button (17): Used by qualified service persons for maintenance.
- Emergency Operation Switch (18): Located on the main unit, this switch allows basic operation if the remote controller is not working (e.g., due to battery failure). The machine runs in the previous mode with previously set air flow direction.
Special Operating Conditions:
- Dry Operation: Designed to decrease room humidity with minimal temperature decrease. The microcomputer automatically determines temperature and fan speed. It does not operate if room temperature is below 16°C.
- Defrost Operation (Heating Mode): When frost accumulates on the outdoor unit coil, heating effect decreases, and the system enters defrost operation. The indoor unit fan stops, the DEFROST lamp illuminates, and after 6-10 minutes, the system returns to heating.
- Master Remote Controller Designation (for VRV systems): In systems with multiple indoor units or BS units, one remote controller must be designated as the master. Only the master can select HEATING, COOLING, or AUTOMATIC operation. Slave units follow the master's mode, but can adjust fan speed and air flow direction within the master's selected mode.
Maintenance Features
- Battery Replacement: The remote controller uses two AAA.LR03 alkaline batteries. Batteries should be replaced when the indoor unit does not respond, responds slowly, or the display becomes dark (typically once a year). All batteries should be replaced at the same time, and old and new batteries should not be mixed. If the remote controller is not used for a long time, batteries should be removed to prevent leakage.
- Air Filter Cleaning Time Indicator Lamp (22): Lights up when the air filter needs cleaning. After cleaning, the filter sign reset button on the remote controller should be pressed to turn off the lamp.
- Troubleshooting (Malfunction Code Display): If the air conditioner stops due to an emergency, the run lamp on the indoor unit blinks. The remote controller can display a malfunction code (e.g., A1-UF) which helps diagnose the problem. Users are instructed to contact their dealer with this code for faster repair.
- Disposal Requirements: The product and batteries are marked with symbols indicating they should not be mixed with unsorted household waste. They must be treated at specialized facilities for re-use, recycling, and recovery. Batteries containing heavy metals (e.g., Pb for lead) are also indicated. Users are advised not to dismantle the system themselves and to contact a qualified installer or local authority for proper disposal.
Safety Precautions (General):
- Avoid prolonged, direct exposure to cool or warm air.
- Turn off power and contact a dealer if the unit malfunctions (e.g., burning odor).
- Installation, modification, repair, and maintenance should be done by a local dealer.
- Do not insert objects into air inlet/outlet.
- Beware of fire in case of refrigerant leakage; ventilate the room and do not use naked flames.
- Use dedicated power supply and correct fuses.
- Install an earth leakage breaker and earth the unit properly.
- Do not operate the unit by turning the power supply breaker ON/OFF.
- Avoid using the product in atmospheres contaminated with oil vapor, excessive oily smoke, flammable/corrosive gas, or metal dust.
- Do not use flammable sprays or organic solvents near the unit.
- Do not use the air conditioner for purposes other than its intended use (e.g., cooling precision instruments, food, plants, animals, or works of art).
- Ensure adequate ventilation if other burning equipment is used in the same room.
- Check unit stand and mounts for damage after prolonged use.
- Do not operate with wet hands.
- Do not place heaters or naked flames directly below the unit.
- Do not block air inlets/outlets.
- Do not wash the unit or remote controller with water.
- Do not place water containers on the unit.
- Do not install where flammable gas leakage is possible.
- Do not place flammable containers within 1m of the blow-off mouth.
- Ensure complete drainage from the outdoor drain pipe.
- Children should be supervised to prevent play with the unit or remote controller.
- Do not touch internal parts of the controller.
- Do not leave the remote controller where it might get wet.
- Avoid strong light beams or inverter fluorescent lamps near the receiver.
- Exercise caution during air filter cleaning or inspection, especially when working at heights.
