Daikin Brc1c51 61 Installation Manual Extra Quality -
The Daikin BRC1C51/61 is a wired remote controller used primarily for ducted and VRV air conditioning systems. The installation manual provides critical procedures for mounting, wiring, and initial configuration to ensure the system operates correctly without electrical interference. Key Installation Procedures
The installation process is divided into physical mounting and technical electrical connection: Preparation: Disconnect all power before starting work.
Separate the upper case (which contains the PCB) from the lower case using a flathead screwdriver in the designated recesses. Mounting the Lower Case:
Select a flat mounting surface and avoid over-tightening screws to prevent deforming the plastic, which can make the upper case difficult to snap back on.
Route wires through the top, rear, or bottom center outlets before securing the case to the wall. Wiring and Connection:
Terminals: Connect the remote controller terminals (P1, P2) to the corresponding terminals on the indoor unit.
Polarity: These wires are non-polar, meaning it does not matter which wire goes to which P1/P2 terminal. Cable Specs: Use 2-core sheathed vinyl cord or cable ( ) with a maximum length of 500 meters.
Noise Prevention: Keep control wiring at least 1 meter away from power lines and electronic devices (like TVs or radios) to avoid electrical noise interference. Field and Hardware Settings
After installation, specific configurations may be required:
Main/Sub Controller: If controlling one unit with two controllers, one must be set as the "Sub RC" by holding the Mode button for 4 seconds during power-up.
Hardware Jumpers: The board may have jumpers to adjust the temperature range (e.g.,
) or to activate/deactivate the "Turbo" and "Quiet" features.
Field Settings: Access the service settings menu by holding the Mode button for 4 seconds or longer to adjust "Mode No." values for specific system behaviors like group control. Troubleshooting Common Install Errors
Error Code U5: Typically indicates a communication error or failure to designate a Sub-controller when two controllers are used.
Blank Screen: Often caused by poor P1/P2 connections or damage to the PCB during installation. daikin brc1c51 61 installation manual
Temperature Inaccuracy: Ensure the controller is not installed in direct sunlight or near heat sources, as this affects the internal sensor.

The Daikin BRC1C51/61 is a wired remote controller used primarily for ducted split systems and SkyAir units. While many users look for a combined manual, these models often share a similar installation interface and basic setup procedures. Pre-Installation Requirements
Location Selection: Install the controller in a place where the average room temperature can be accurately detected. Avoid locations near heat sources or in direct sunlight.
Wiring Precautions: Keep control wires at least 3.5 feet (1 meter) away from televisions or radios to prevent signal interference. Use only copper wire and ensure all electrical work conforms to local codes.
Safety: Always shut off the power supply before beginning any installation work to avoid electric shock. Physical Installation Steps
Back Plate Mounting: Remove the back plate from the controller. Place the top of the controller on the top of the back plate and snap the bottom into place.
Routing Wires: Route the control wire through the top center outlet of the lower case before securing it to the wall.
Wall Attachment: Use the provided screws to fix the lower case to a flat surface. Do not over-tighten the screws, as this can deform the case. Configuration & Field Settings Installation Manual - WIRED REMOTE CONTROLLER
Daikin BRC1C51/61 is a wired remote controller specifically designed for VRV systems and Heat Reclaim Ventilation (HRV) units. Installing it correctly ensures precise climate control and access to advanced features like 24-hour programming and HRV integration. 1. Pre-Installation Safety and Requirements
Before starting, ensure all power supplies to the indoor unit and HRV are shut off to prevent electric shock.
Location Selection: Install on a flat surface away from direct heat sources, high humidity, or electromagnetic radiation.
Wiring Separation: Keep controller wiring (P1, P2) separate from power lines to avoid electrical noise interference.
Protection: Use putty to seal the wiring lead-in hole, preventing insects or moisture from entering the casing. 2. Mounting the Controller The Daikin BRC1C51/61 is a wired remote controller
Disassemble the Casing: Insert a flat-head screwdriver into the recesses at the bottom of the controller to carefully pop off the upper casing. Avoid touching the internal PCB directly.
Attach the Back Plate: Use the provided wood screws to fix the back plate to the wall. Do not over-tighten, as a deformed plate can prevent the upper casing from snapping back on correctly.
Route the Cables: Feed the two-core transmission wire through the rear or side outlets of the lower case before securing it to the wall. 3. Wiring Connections BRC1C51/61 uses a non-polar two-wire connection system.
Terminals: Connect the wires to terminals P1 and P2 on the controller's terminal block.
Indoor Unit: Connect the other end of these wires to the corresponding P1/P2 terminals on the indoor unit's control board.
No Polarity: Because the signal is non-polar, it does not matter which wire goes to P1 or P2, simplifying the installation. 4. System Configuration and Field Settings
Once mounted and wired, the controller must be configured for the specific system.
Initial Power Up: Upon turning on the power, the controller will display "88" while it performs a self-diagnosis.
Master/Sub Settings: If using multiple controllers for one unit, one must be designated as the "Master" and others as "Sub" controllers.
HRV Integration: If controlling an HRV unit, you may need to set the unit to "VENTILATION" mode via the controller's mode selector.
Field Settings: Access the field setting mode (typically by holding the "Test" button for 4 seconds) to adjust parameters like filter sign intervals or external static pressure. 5. Final Checklist and Handover How to Install Daikin AC Remote Control Mount on Wall

Where to get the full manual
- For exact wiring diagrams, DIP switch settings, and detailed menus, obtain the official Daikin BRC1C51/BRC1C61 installation manual or service manual from Daikin or an authorized dealer.
If you want, I can search for and summarize specific wiring diagrams or provide step-by-step DIP-switch/menu settings — tell me which model (BRC1C51 or BRC1C61) and whether you need wiring, address configuration, or sensor hookups.
Getting your Daikin BRC1C51/61 remote controller set up correctly is essential for managing your system efficiently. This wired controller is commonly used with Daikin's VRV and SkyAir systems.
Below is a helpful summary of the installation and initial setup steps based on standard Daikin technical manuals 1. Pre-Installation Check Power Off: shut off the main power supply at the circuit breaker before starting any electrical work.

3. Installation Location Guidelines
Before running wires, choose the location carefully:
- Height: Typically installed 1.0m to 1.5m (approx. 3.3ft to 4.9ft) from the floor.
- Avoid:
- Direct sunlight.
- Areas near heat sources (radiators, stoves).
- Areas with high humidity or water splashes.
- Areas with dust, oil, or corrosive gases.
- Dead air spots (corners where the sensor won't read the room temperature accurately).
- Locations near the air discharge of the indoor unit (affects thermostat reading).
2. Specifications
- Power Supply: Power is supplied from the corresponding indoor unit (typically 12V–16V DC via the transmission cable). It does not require a separate external power source.
- Ambient Temperature: 0°C to 40°C (32°F to 104°F).
- Humidity: Less than 80% (non-condensing).
- Wiring: Uses 2-core non-shielded cable.
Maintenance & Troubleshooting
- Routine: clean front panel with a dry cloth; do not use solvents.
- If display is blank: confirm power supply and terminal wiring.
- Communication error: verify bus wiring, address settings, and terminal tightness.
- Refer to error codes (if displayed) and indoor unit manual for corrective actions.
5. Address Setting
- For multi-system control (e.g., one remote controlling multiple indoor units or group control).
