Indoor/outdoor combination failure or improper field setting. Verify system compatibility.
The BRC1C51/61 utilizes a simple, non-polar two-wire connection system, meaning you do not need to worry about reversing the positive and negative lines.
The Daikin BRC1C51 61 installation manual provides detailed instructions for a successful installation. By following this guide and consulting the manual, you'll be able to:
: Use non-shielded, 2-conductor, stranded copper wire, typically AWG-18.
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.
: 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
Connect the two wires to terminals and P2 on the remote controller backplate block.
Route the 2-core communication wire through the central wiring lead-in hole of the back plate.
Two-core vinyl-insulated sheath cable or cord (0.75 mm² to 1.25 mm²) Standard electrical switch box (if flush-mounting) 2. Safety Precautions
: 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.
: The maximum allowable wiring length is 500 meters (1,640 feet) .
Fasten the lower case to a flat surface using the provided screws.
Separate the upper case (which contains the PCB) from the lower case using a flathead screwdriver in the designated recesses. :
: Includes "pre-operation" checklists, such as checking for foreign objects in the unit and ensuring the unit is mounted in a place strong enough to support its weight to prevent hazardous vibration. DENV | Daikin
