Display

The Control Point panel is equipped with an LCD display. The display functions can be activated or inactivated using the following parameter or in the iSMA Configurator:

DEVICE_CONFIGURATION, BACKGROUND_ILLUMINATION_ LCD_ACTIVE: allows to switch on the LCD background illumination. If true, the LCD display is illuminated with intensity according to values stored in parameters dedicated for particular room panel modes. If false, the LCD display is not illuminated in any mode. By default, the display is illuminated;

• Modbus register: 40205, bit 3;

• BACnet object: BO3, property: Present Value.

During a normal operation, the display shows a main menu (values measured by all sensors available in the panel and a temperature setpoint, with parameter’s shortcut name and a proper unit) and submenu icons.

The display configuration parameters include the following (these functions can be edited directly in the parameters or in the iSMA Configurator):

REFRESH_TIME: sets the duration of the display time of particular parameters. When the refreshing time elapses, the next parameter is displayed according to the sequence of parameters display. The default value is 2 seconds (each parameter is displayed for 2 seconds). The minimum refreshing time is 1 second.

• Modbus register: 40217;

• BACnet object: AO13, property: Present Value.

Display Brightness

Display brightness switches between three illumination modes in time:

• active mode;

• idle mode;

• standby mode.

Active Mode Settings

BACKGROUND_LCD_FOR_ACTIVE_MODE: allows to set a value of the LCD display brightness in the active mode (expressed in %). The default value is 60%.

• Modbus register: 40207;

• BACnet object: AO3, property: Present Value;

BACKGROUND_LCD_TIME_TO_IDLE: allows to set the time, after which the LCD display goes from the active mode to idle (expressed in seconds). The default value is 10 seconds.

• Modbus register: 40210;

• BACnet object: AO6, property: Present Value;

Idle Mode Settings

BACKGROUND_LCD_FOR_IDLE_MODE: allows to set a value of the LCD display brightness in the idle mode (expressed in %). The default value is 40%.

• Modbus register: 40208;

• BACnet object: AO4, property: Present Value.

BACKGROUND_LCD_TIME_TO_STANDBY: allows to set the time, after which the LCD display goes from the idle mode to standby (expressed in seconds). The default value is 5 seconds.

• Modbus register: 40211;

• BACnet object: AO7, property: Present Value.

Standby Mode Settings

BACKGROUND_LCD_FOR_STANDBY_MODE: allows to set a value of the LCD display brightness in the standby mode (expressed in %). The default value is 5%.

• Modbus register: 40209;

• BACnet object: AO5, property: Present Value.

The panel stays in the standby mode until next user interface interaction.

Current Display Brightness

BACKGROUND_LCD_CURRENT_VALUE: contains a current display illumination value.

• Modbus register: 30201;

• BACnet object: AI1, property: Present Value.

Editing Parameters

The following parameters allows to set the editing mode behavior:

ENTER_MENU_TIME: allows to set a long-press duration to enter the submenu and settings menu;

• Modbus register: 40223;

• BACnet object: AO16, property: Present value;

EXIT_MENU_TIME: allows to set the time after which the panel exits the submenu and settings menu:

• Modbus register: 40225;

• BACnet object: AO18;

EXIT_MENU_TIME: allows to set the time after which the panel exits the editing mode:

• Modbus register: 40224;

• BACnet object: AO17.
