Heat-lock mode
Heat-lock mode is a special mode designed to use in cases like a summer

an easier control for the lighting. Once under the heat-lock mode, any button
will be changed to a light switch and can't be used to change the heating
setting.
To enter the heat-lock mode, please press and hold the "Power" button until
the screen shows "HL", to quit, press and hold the "Power" button again
