LCD Display

The iSMA-B-LP room panel is equipped with 2.3” LCD display with backlight.

By default, the LCD display is turned on (when the device is powered) and basic parameters from in-built sensors together with the user-defined parameters are shown in the main menu. 

The register DEVICE_CONFIGURATION bit 11 is responsible for the LCD display and keypad activation.

If the bit is false, the LCD display and keypad work in normal mode (parameters and actual sensor values are displayed, submenus are visible and editable, etc.).

If the bit is true, the LCD display and keypad are deactivated. The room panel works as a simple sensor. (CO₂ sensor, temperature sensor, humidity sensor–depending on the room panel version).
