After power-on, the LCD will enter the main interface after about 60s. The main interface provides the general
information about relative equipment status, including current temperature and humidity; temperature and
humidity setpoints; equipment output status (fan, water valve, cooling, heating, dehumidifying, humidifying);
alarm and maintenance status.
The main interface has two display modes: Graphical and Simple. The dierence between these two display
modes is that the graphical interface (see Figure 4-3) displays the percentage output chart of the function
components, while the simple interface (see Figure 4-4) displays only the icons of current operation mode only.
The switching of two modes can be realized by operating the menu. For details, refer to DISPLAY SETUP.
The upper left corner of the main interface displays the current unit number; the upper right corner displays the
current system status If there is no button operation for 255sec on other menu display screen, the LCD screen
returns to the main interface.
