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.

Temperature Inaccuracy: Ensure the controller is not installed in direct sunlight or near heat sources, as this affects the internal sensor.

Daikin BRC1C51/61 is a wired remote controller primarily used for controlling Heat Reclaim Ventilation (HRV) units like the VAM-FA series

. While it shares common Daikin installation practices, it has specific wiring and mounting requirements for integration with ventilation systems. Daikintech.co.uk 1. Pre-Installation Preparation Qualified Personnel

: Installation must be performed by qualified persons familiar with local codes and this specific type of appliance. Avoid Interference

: Do not install near machinery emitting electromagnetic radiation or in locations with high concentrations of mineral oil spray (e.g., kitchens). Protection

: Keep the indoor unit and remote controller away from rain or moisture to prevent fire or electric shock. CrispAir Air Conditioning 2. Mounting the Remote Controller Casing Removal

: Insert a flat-head screwdriver into the notched area at the bottom and twist "LIGHTLY" to remove the top casing from the lower part. Wiring Entry

Determine the wiring entry point (top center, rear, or side).

Cut the plastic at the notched area and remove any burrs to avoid damaging the wires.

: Fix the lower part of the remote controller to the wall or a switch box using the provided screws. Daikin Comfort 3. Electrical Wiring Interconnection

: The BRC1C51/61 connects to the indoor unit's P1 and P2 terminals. Routine: clean front panel with a dry cloth;

: The wiring between the remote controller and the indoor unit is

, meaning you can connect the wires to either P1 or P2 without strict positive/negative orientation. Group Control

: One remote can simultaneously control up to 16 indoor/HRV units by daisy-chaining the P1/P2 terminals. Two-Remote Setup

: If using two controllers for one unit, one must be set as "Main" and the other as "Sub" (Sub RC). Failure to set the sub-controller may cause an Error Code: U5 Daikin Comfort 4. Initial Field Settings

Once powered on, specific field settings may be required depending on the installation: Mode Settings : Press and hold the Inspection/Test button for 4 seconds to enter the field setting mode. Sub-Controller Set : If "Main RC" is displayed on both, hold the

button for 4 seconds on the second controller to switch it to "Sub RC". Filter Sign

: The controller includes a filter signal reset button to clear the "Time to clean filter" indicator after maintenance. Daikin Comfort Common Troubleshooting for BRC1C51/61 Error Code U5

: Communication error between the indoor unit and remote controller. Check for loose wiring on terminals P1/P2. No Display

: Ensure the main power is on and the wiring is correctly connected to the indoor unit's PCB.

: If the unit hangs, turn off the breaker for 30 seconds to discharge capacitors, then restart. Airway Group OPERATION MANUAL SPLIT SYSTEM Ducted Air Conditioner

Getting your HVAC system up and running with a Daikin BRC1C51/61 remote controller doesn't have to be a headache. Whether you’re a DIY enthusiast or just want to understand what your technician is doing, this guide breaks down the essential steps found in the installation manual. Before You Start: Safety First

Before touching any wires, ensure the power to the indoor unit is completely switched off. Working with HVAC electrics requires caution, so if you feel unsure, always call in a professional. 1. Choosing the Right Spot

Location is everything. For the most accurate temperature readings:

Avoid Direct Sunlight: Don't mount the controller where the sun hits it.

Stay Away from Drafts: Keep it clear of windows, doors, or direct air discharge from the vents.

Height Matters: Aim for about 1.5 meters (5 feet) above the floor. 2. Wiring the Controller

The BRC1C51 and 61 models use a simple two-wire, non-polar system. This is great news because it means you don't have to worry about which wire goes to which terminal (P1 and P2). Use a 2-core sheathed vinyl cord or cable ( mm2m m squared 1. Safety Precautions WARNING

Run the wire from the indoor unit's terminal block to the back of the remote controller.

Pro Tip: Keep the remote control wiring at least 50mm away from power lines to avoid electrical interference. 3. Mounting the Plate

The controller comes with a mounting plate. Secure this to the wall or an electrical box using the provided screws. Once the plate is level and the wires are pulled through the center hole, click the main body of the controller into place. 4. Field Settings (The Important Part)

Once powered on, you may need to configure "Field Settings" to tell the unit how to behave. This is done by holding the Inspection/Test button for 4 seconds. Mode No. 10: Used for setting things like filter signs.

Mode No. 12: Used to define the "Cool/Heat Selection" master if you have multiple units. 5. The Test Run

Don't just walk away! Perform a test run by pressing the Inspection/Test button twice. The unit will run for a short period to confirm the fan, cooling, and heating cycles are functioning correctly.

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
