If a fault develops, the microprocessor will display a unique fault code (e.g., A1) on the remote controller screen. If this occurs, take a note of the fault code and contact your Daikin dealer. This code will help the technician quickly identify the problem.
The table below shows examples of common field settings you may need to configure. daikin brc1c51 61 installation manual
Direct sunlight or near heat sources (lamps, radiators, electronics). If a fault develops, the microprocessor will display
Check the circuit breaker and ensure the wires are securely connected to the terminal block ( The table below shows examples of common field
Check main circuit breaker; verify continuity across the P1 and P2 wires using a multimeter.
Connect the wires to the matching and P2 terminals on the indoor unit's terminal block. Because the system is non-polar, it does not matter which wire goes to P1 or P2, as long as they form a complete circuit.
Strip away exactly of outer insulation from both control wire conductors. Insert these leads into the designated terminal connector block (labeled CN_WIR or P1/P2 ) on the upper housing PCB.
