: Ensure the controller is not installed in direct sunlight or near heat sources, as this affects the internal sensor.
Connect the ribbon cable (if your version has one) or simply align the top hooks of the controller with the top edge of the wall plate. Press the bottom edge until you hear a .
Polarity does not matter. Daikin uses non-polarized transmission. However, use a twisted pair or shielded cable to prevent electrical noise.
The official installation manual, which contains all the necessary wiring diagrams and safety information, is best sourced directly from Daikin's official channels. While this article serves as a guide, always refer to the original documentation for the final authority on the installation.

The BRC1C61 is a specifically paired with the installation manual that comes with Daikin's ducted and ceiling-mounted indoor units (such as the FBQ or FXDQ series). It communicates directly with the indoor unit via low-voltage transmission wiring . While there is a slight model variation (BRC1C51 vs. BRC1C61), their specifications and installation are identical for practical purposes. Both models allow for wired control of the unit, setting it apart from wireless remotes by offering a permanent, wall-mounted interface that does not require line of sight to function.

Tip: If the room temperature reading seems wrong, flip SW3 to ON if you have an external sensor wired to the indoor unit.
Because the wiring is , it does not matter which wire goes to P1 or P2.
Before beginning the physical installation, verify that the controller kit contains all original parts. If any components are compromised or missing, contact your authorized Daikin Comfort dealer immediately. Box Inventory Polarity does not matter
Once the wiring is routed to the desired location and the wall/ceiling reinforcement is finished:
: 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
