: Insert a flathead screwdriver into the recesses at the bottom of the lower case to gently pry off the upper case. Be careful not to damage the internal printed circuit board (PCB).
: Technicians may need to adjust physical jumpers on the PCB to set temperature ranges (e.g., limiting the range to 20°C–30°C) or activate room temperature displays.
The setting is confirmed only after all steps are completed; otherwise, it will exit after 5 seconds of inactivity. daikin brc1c51 61 installation manual
: Mount the lower case (back plate) to a flat wall or pillar using the provided screws. Avoid over-tightening, as this can deform the plate and prevent the upper case from snapping on correctly.
: Use putty or a similar sealant to close the wiring lead-in hole to prevent water, dust, or insects from entering. 2. Wiring and Connections : Insert a flathead screwdriver into the recesses
: Connect the two-core remote controller wire to terminals P1 and P2 on the controller's PCB. These terminals are not polarity sensitive , meaning the wires can be connected in either position.
The installation involves mounting the controller and connecting it to the indoor unit's control board. The setting is confirmed only after all steps
: If controlling multiple units, the remote is connected to the first unit, and subsequent units are daisy-chained via their P1/P2 terminals. Initial Setup and Configuration
