Use a pair of pliers or wire cutters to remove the thin plastic knockout tab at the top or side of the controller casing. This creates an entry point for the wire.

: The other end of the cable connects to the P1 and P2 terminals on the indoor unit's control box. 4. Hardware and Field Settings

Press and hold the for at least 4 seconds.

: 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.

Locate the two small slots at the bottom edge of the BRC1C51/61 housing. daikin brc1c51 61 installation manual

Hook the top tabs of the front assembly into the top slots of the mounted rear plate. Pivot the lower half of the controller downward.

: The controller may be mounted in a drafty area or near a heat source. Modify Field Setting 10-2 to utilize the indoor unit's return air thermistor instead of the remote controller's sensor. If you need help configuring specific settings, tell me: What model of indoor unit is connected?

Non-polar, 2-core, stranded copper wire. Shielded cable is recommended in environments with high electromagnetic interference (EMI). Wire Size: 0.75 mm² to 1.25 mm² (AWG 18 to AWG 16).

: 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 Use a pair of pliers or wire cutters

: Upon turning on the power, the controller will display "88" while it performs a self-diagnosis.

Use a two-core cable (sheathed vinyl cord or cable, 0.75 to 1.25mm²).

If you need help with a specific part of the setup, let me know: Locate the two small slots at the bottom

What (if any) is showing on your screen?

Turn off the main power supply at the circuit breaker sourcing the indoor unit and outdoor condenser. Working on live control lines can short-circuit the indoor unit main board. Step 2: Route the Cable

Two controllers manage a single indoor unit (e.g., up and down stairwells). One unit must be designated as the Master and the other as the Slave via its internal dip switch or field settings.

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.

If the unit requires configuration (such as external static pressure adjustment), enter the Field Setting mode as described in the BRC1C51/61 service manual. 4. Troubleshooting Installation Issues

If connecting multiple indoor units to a single remote controller (Group Control), daisy-chain the P1/P2 terminals from the first indoor unit to the subsequent indoor units. A maximum of 16 indoor units can be linked in a single group. Configuring Master and Slave Controllers
