After power-on, the LCD will enter the main interface after 20s. The main interface provides the general information of
the relative equipment status, including current temperature and humidity, temperature and humidity set points,
equipment output status (fan, compressor, cooling, heating, dehumidifying, humidifying), alarm and maintenance

The main interface has two display modes: graphical and simple. The difference between the two display modes is
that the graphic interface (see Figure 5-4) displays the percentage output chart of the function components while the
simple interface (see Figure 5-5) displays the icons of current operation mode only. The switching of two modes can
be realized by operating the menu. For details, refer to 5.6.8

button operation for 255s on other menu display screen, the LCD screen will return to the main interface.
