  1. Press the MODE button.

  2. Cycle through the options: Cool, Heat, Fan, Dry, Auto (depending on your model).

  3. Stop on the mode you want; the remote and unit will show the selected mode.

3. Setting the Temperature

  1. Use the â–² (Up) and â–¼ (Down) buttons on the remote to adjust the set temperature.

  2. To reset the remote to default settings (rare feature), refer to the manual — often holds a RESET switch or a button combo.

9. Monitor Display / Unit Indicators

  • Check the indoor unit’s display for current mode, fan speed, temperature, and any error indicators.

  • If an error code appears (e.g., “E1”, “H3”), consult the unit’s user manual or technician guide.
