This document provides a comprehensive operation manual for the Daikin Wired Remote Controller, models BRC230Z4, BRC230Z8, BRC24Z4, and BRC24Z8. It covers essential information from basic button functions to advanced timer and zone control settings, as well as maintenance procedures.
Read Before Operation
The manual begins by detailing the Name and Functions of Buttons on the remote controller. This section serves as a quick reference to understand the purpose of each button, ensuring users can navigate the device effectively. Key buttons include:
- ON/OFF button: Used to turn the air conditioner ON or OFF.
- MODE selector button: Allows selection between AUTO, COOL, HEAT, DRY, and FAN modes.
- FAN setting button: Adjusts the airflow rate.
- TEMPERATURE adjustment button (▲ TEMP / ▼ TEMP): Used for temperature adjustment and other settings.
- 7 DAY TIME CLOCK button: Accesses the setting display for Simple and Multi 7-Day Timers.
- ON/OFF TIMER button: Sets ON and OFF timers.
- SHIFT button: Changes the display during settings.
- ENTER button: Confirms and accepts settings.
- CLEAR button: Cancels settings.
- TEST/EXIT button: Exits programs.
- DAY/TIME button: Navigates to the clock and day setting.
- SELECT SENSOR button: For sensor selection.
- FIXING SENSOR button: Enters the selected sensor.
- ZONE button: For making zone settings.
- DISPLAY: The LCD screen that shows current settings.
The manual also explains that two remote controllers can be connected to the system, functioning as master and sub units. The sub remote controller mirrors the master's functions, except for time and day settings, which are exclusively set on the master.
The Preparation before Operation section guides users through initial setup, starting with Turning the breaker ON. It emphasizes that if nothing is displayed on the LCD, the breaker should be turned ON.
A crucial part of the preparation is Time and Day Settings. This step is vital for the proper functioning of timer operations. The process involves:
- Identifying if "Mo", "00:00", and "SET" are blinking, indicating no time/day settings have been made.
- Pressing the "DAY/TIME button" to access the setting screen.
- Using the "SHIFT button" to enter adjustment mode, where "Adjust." and "Mo" blink.
- Selecting the day (Mo → Tu → We → Th → Fr → Sa → Su) using the "▲ TEMP / ▼ TEMP buttons".
- Pressing "SHIFT button" again to move to time setting, where "0000" blinks.
- Adjusting the present time using the "▲ TEMP / ▼ TEMP buttons".
- Pressing the "ENTER button" to confirm and save the settings.
Instructions are also provided for Cancelling Time and Day Settings, by pressing the "CLEAR button" for at least 4 seconds, which resets the settings and makes "Mo" and "SET" blink again.
Notes on energy saving are included, advising users to maintain moderate temperature settings and use blinds/curtains to block sunlight, thereby improving cooling efficiency. It also reminds users that the air conditioner consumes a small amount of electricity even when off and recommends turning the breaker OFF for long periods of non-use, switching it back on 6 hours before operation.
Operation
The FAN · DRY · AUTO · COOL · HEAT Operation section details how to use the air conditioner in various modes.
To start operation:
- Press the "MODE button" to select the desired operation mode (FAN → DRY → AUTO → COOL → HEAT).
- Press the "ON/OFF button" to start the air conditioner in the selected mode.
To stop operation, simply press the "ON/OFF button" again.
To change the temperature setting:
- Press the "▲ TEMP / ▼ TEMP buttons".
- In DRY or FAN mode, temperature setting is unavailable.
- In AUTO, COOL, or HEAT mode, adjust the temperature between 16°C and 32°C using the "▲ TEMP / ▼ TEMP buttons".
To change the airflow setting:
- Press the "FAN button" to select the airflow rate.
- Airflow volume is selectable from two levels in normal or AUTO fan mode.
Notes on specific operation modes provide important context:
- HEAT operation: Explains that heating capacity drops in lower outdoor temperatures due to heat absorption from outdoor air. It also mentions defrosting operations, during which warm air will not flow from the indoor unit.
- COOL operation: Clarifies that cooling performance drops if the outside temperature is high, as heat is released outdoors.
- DRY operation: States that the computer chip automatically controls temperature and fan strength to remove humidity, making manual adjustment unavailable.
- AUTO COOL/HEAT operation: Describes how the system selects COOL or HEAT based on room temperature and automatically reselects settings to maintain the user-set level.
- Airflow rate setting: Explains that the fan may stop for 6 minutes continuously and then operate for 30 seconds when AUTO fan speed is selected and the room temperature is within the selected range. It also notes that AUTO fan function operates differently if "Indoor Sens" is not selected.
The TIMER Operation section covers how to use ON and OFF timers to automatically switch the air conditioner.
