While the privacy lock feature on Gree AC remote control is a useful tool to prevent unauthorized access to AC settings, it can also be frustrating for those who want to change their temperature settings. However, it's possible to change the temperature while the privacy lock is enabled. The privacy lock only locks the buttons on the remote control, not the AC unit itself. Therefore, you can still turn your AC on and off even with the privacy lock enabled. To change your temperature settings while locked, simply press and hold both the Up ▲ and Down ▼ buttons simultaneously until the desired temperature is reached. Understanding how to use your Gree AC remote control properly can prevent accidental lockouts and give you more freedom in adjusting your preferred temperature setting.
