Daikin Brc1c51 61 Installation Manual -

Once powered, the controller will usually auto-detect the indoor unit, but you may need to configure settings:

  • Thermistor Sensor Selection:
  • Use solid-core or stranded copper wire as specified (often 0.5–1.5 mm² / 20–16 AWG).
  • Ensure correct polarity where applicable and tighten terminal screws firmly.
  • Keep wiring length and routing per manufacturer limits; avoid running parallel to high-voltage lines.

    • Disclaimer: This summary is for informational purposes. Installation of commercial HVAC controls carries the risk of electric shock and equipment damage. Installation should only be performed by a qualified technician or electrician.

    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

    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 daikin brc1c51 61 installation manual

    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 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). Once powered, the controller will usually auto-detect the

    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
