: 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.

: 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

: 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

: If two remote controllers are used for one unit, one must be designated as the "Sub RC." Hold the Mode button for 4 seconds or longer until the display changes from "Main RC" to "Sub RC". Troubleshooting Common Issues

: Shut off all power supplies to the indoor and outdoor units to prevent electric shock.

The installation involves mounting the controller and connecting it to the indoor unit's control board.

Before starting, observe these mandatory safety precautions:
