Once you have identified the MODE button, press it repeatedly until the “AUTO” mode is displayed on the LCD screen of your YORK air conditioner. This will indicate that the unit is now in the auto mode, ready to automatically adjust its operation based on the preset temperature and environmental conditions.

Setting the Desired Temperature

With the auto mode selected, the next step is to set the desired temperature. YORK air conditioners typically have a temperature range of 60.8°F to 86°F (16°C to 30°C), allowing you to customize the comfort level to your preference. To adjust the temperature, use the temperature adjustment buttons, which are often labeled with up and down arrows or “+” and “-” symbols.

Initiating the Air Conditioner

After setting the desired temperature, press the ON/OFF button to start the YORK air conditioner. In the auto mode, the indoor fan will operate automatically, and you will not be able to manually adjust its speed.

Adjusting the Fan Speed (Optional)

If you wish to adjust the fan speed, you can do so by pressing the FAN SPEED button. YORK air conditioners typically offer four fan speed options: auto, low, medium, and high. Selecting the appropriate fan speed can help optimize the air circulation and cooling/heating performance based on your personal preferences and the environmental conditions.

Stopping the Air Conditioner

To turn off the YORK air conditioner, simply press the ON/OFF button again. This will stop the unit’s operation and return it to the standby mode.

Understanding the Auto Mode Operation

The auto mode in YORK air conditioners operates according to the factory-preset settings for standard heating and cooling temperatures. During cooling operation, the protection function is the same as that under the cooling mode. During heating operation, the protection function is the same as that under the heating mode.

This means that the YORK air conditioner will automatically adjust its operation to maintain the desired temperature, switching between cooling and heating modes as needed to achieve the optimal comfort level. The indoor fan will also adjust its speed accordingly to ensure efficient air circulation and distribution.

Technical Specifications and Considerations

YORK air conditioners are designed with advanced features and technologies to ensure optimal performance and energy efficiency. Some key technical specifications and considerations to keep in mind when operating your YORK AC unit in the auto mode include:

Compressor Operation

The compressor in your YORK air conditioner plays a crucial role in the auto mode operation. It will automatically start and stop as needed to maintain the desired temperature, with the protection function ensuring safe and efficient operation.

Refrigerant Charge

The proper refrigerant charge is essential for the YORK air conditioner to operate effectively in the auto mode. Ensure that the refrigerant level is within the manufacturer’s recommended range to avoid performance issues or potential damage to the unit.
