Temperature Unit Setting – Fahrenheit to Celsius
How to change the wireless remote controller display between °F and °C
Use the following procedure when the remote controller is displaying temperature in Fahrenheit (°F) and needs to be changed to Celsius (°C), or vice versa.
Procedure
| Step | Action | What you should see |
|---|---|---|
| 1 | Turn the air-conditioning system OFF using the START/STOP button on the remote controller. | The unit is stopped before entering the temperature-unit setting. |
| 2 | Press and hold the TEMP. UP (▲) button until the clock display disappears. | A temperature value appears in the centre of the display with either °C or °F. |
| 3 | Press the TEMP. DOWN (▼) button to change the temperature unit. | The display toggles between °C Celsius and °F Fahrenheit. |
| 4 | When the required unit is displayed, press the START/STOP button. | The controller exits the temperature-unit setting and returns to normal operation. |
Important: The selected temperature unit is retained if the remote-controller batteries are replaced or if the controller is hard reset.
Quick change – °F to °C
System OFF → Hold TEMP ▲ → Wait for °F / °C setting to appear → Press TEMP ▼ until °C is shown → Press START/STOP to exit
If the setting does not appear
- Confirm the air conditioner has been turned off using the remote controller before starting the procedure.
- Continue holding TEMP ▲ until the normal clock display disappears.
- If the remote-controller layout or buttons differ from those described above, refer to the operating manual for the specific remote controller.
Note: This procedure applies to remote controllers that support this temperature-unit setting method. Button layout and available settings can vary by controller model.
