The Daikin BRC1C51 and BRC1C61 are wired remote controllers typically used with Daikin Heat Reclaim Ventilation (HRV) and split systems. The installation process involves mounting the lower case to a flat surface and connecting it to the indoor unit's printed circuit board (PCB). Installation Steps Preparation: Ensure the power is shut off before beginning.
Disassemble the Case: Use a screwdriver in the recesses of the lower case to gently pry off the upper case. Be careful not to damage the PCB attached to the upper case.
Wiring Path: Choose the wiring entry point (top center, top right, or bottom) and cut the plastic at the notched area.
Mount the Lower Case: Route the wire through the entry hole and secure the lower case to the wall using the provided screws. Do not overtighten to avoid deforming the case.
Connections: Connect the 2-conductor wire to the CN_WIR connector on the controller's PCB and to terminals P1/P2 on the indoor unit's PCB. These terminals are not polarity sensitive.
Reassembly: Align the upper case with the tabs on the lower case and snap it back into place. Key Specifications
Wiring: Use non-shielded, 2-conductor, stranded copper wire, typically AWG-18.
Max Distance: The maximum allowable wiring length is 500 meters (1,640 feet).
Location: Install at least 1 meter away from TVs or radios to prevent electromagnetic interference. Avoid areas with direct sunlight, high moisture, or corrosive gases. Manual Resources

The Daikin BRC1C51/61 is a wired remote controller used to manage split-system and ducted air conditioning units. Installing it involves mounting a lower case, routing control wiring to the indoor unit, and snapping the upper case into place. 1. Choosing the Installation Site
Surface: Select a flat wall surface to avoid deforming the controller's lower case when tightening screws.
Environment: Avoid areas exposed to direct sunlight, moisture, or heat sources. daikin brc1c51 61 installation manual
Interference: Keep the controller and its wiring at least 3.3 to 3.5 feet (1 meter) away from televisions and radios to prevent electrical noise. 2. Mounting the Lower Case
Open the Controller: Use a screwdriver to lightly twist and release the tabs at the bottom to remove the upper case.
Prepare Wiring Entry: Cut out the plastic at the notched areas (top center, right, or bottom) for the wiring to enter the case.
Fix to Wall: Route the wire through the chosen hole and secure the lower case to the wall using the provided wood screws or small screws. 3. Wiring and Final Assembly
Connection: Connect the control wire to the CN_WIR connector on the printed circuit board (PCB) located on the upper case.
Indoor Unit Link: Connect the other end of the wire to the indoor unit's PCB, typically at the CN_NS connector for compatible models like the FTK/FTX series.
Snap On: Align the upper case with the four tabs on the lower case and press firmly until it clicks into place. Finish: Peel off the protective sheet from the display. 4. Initial Setup
Clock: To set the time, hold the timer button for 5 seconds until the display blinks. Use the arrow buttons to adjust the minutes and day of the week, then confirm.
Test Run: Turn on the main power. The system should take about 15–20 seconds to power up, after which you can test basic ON/OFF and mode functions. Operating Manual | Daikin Comfort
Daikin BRC1C51/61 is a legacy wired remote controller primarily used for controlling split system ducted air conditioners and Heat Reclaim Ventilation (HRV) units. It is valued for its straightforward, mechanical-button interface that provides essential climate control without unnecessary complexity. Key Features & Functions Essential Controls
: Provides standard functions including ON/OFF, operation mode change-over, temperature adjustment (16–32°C), and air volume/flow direction control. System Indicators
: Features a clear display for operation mode, fan speed, and centralized control status (indicated by a specific icon when managed by a master controller). Maintenance Alerts
: Includes a "FILTER" indication to notify users when the HRV unit or air conditioner filter requires cleaning. Timer Capabilities
: Allows for programmed start/stop times in 1-hour increments up to 72 hours in advance. Installation Insights The Daikin BRC1C51 and BRC1C61 are wired remote
The installation manual emphasizes professional setup to ensure safety and system longevity. Key requirements include:
: Must be installed on a flat surface away from direct sunlight, heat sources, and moisture to prevent electrical failure or inaccurate temperature sensing. Wiring Precautions
: Control wires should be kept at least 1 meter (3.5 feet) away from TVs or radios to avoid signal interference.
: The lower case is fixed to the wall with provided screws, and the upper case—which contains the PCB—is snapped into place using specific alignment tabs (typically 4–6 points). Safety First : It is strongly recommended that a qualified service person
performs the installation to avoid risks of electric shock, fire, or water leakage from improper setup. OPERATION MANUAL
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: BRC1C61 only has DIP switches inside (under the
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.
Temperature Inaccuracy: Ensure the controller is not installed in direct sunlight or near heat sources, as this affects the internal sensor.
