Device Configuration

DEVICE_CONFIGURATION: allows to configure the following parameters:

• BUZZER: allows to activate or deactivate the buzzer. When the buzzer is active, any single push of any button is signalized by the buzzer sound. In addition, the buzzer can be also used for CO₂ alarm signalization. By default, the buzzer is active;

  • Modbus register: 40205, bit 0;

  • BACnet object: BO0;

• TIME_FORMAT: allows to define a time format display. If true, the time is set to 12-hour format. If false, the time is displayed in 24-hour format (default). When the clock is set in 12-hour format and it receives hours value in 24-hour format, icons AM and PM are displayed according to calculation. A semicolon, which separates hours and minutes sections in the clock, flashes with 1 Hz frequency;

  • Modbus register: 40205, bit 1;

  • BACnet object: BO1;

• DEFAULT_TEMPERATURE_UNIT: allows to set a default temperature unit to Celsius or Fahrenheit degrees;

  • Modbus register: 40205, bit 2;

  • BACnet object BO2;

• 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;

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

  • Modbus register: 40205, bit 4;

  • BACnet object: BO4;

• CO2_IN_ALARM_FLASHING_LCD: allows to switch on the function of LCD background illumination flashing when CO₂ alarm occurs. If true, the CO₂ alarm is indicated by the LCD display flashing. Read more about CO₂ alarm in the CO₂ sensor section. By default, the function is deactivated;

  • Modbus register: 40205, bit 5;

  • BACnet object: BO5;

• CO2_IN_ALARM_BUZZER: allows to switch the buzzer on when the CO₂ alarm occurs. If true, the CO₂ alarm is indicated by the buzzer, which emits sounds with 1 Hz frequency. Read more about CO₂ alarm in the CO₂ sensor section. By default, the function is deactivated;

  • Modbus register: 40205, bit 6;

  • BACnet object: BO6;

• CO2_IN_ALARM_SHOW_HIGH: allows to switch on a “HIGH” label on display when the CO₂ alarm occurs. If true and the CO₂ alarm is active, the LCD display shows the CO₂ sensor actual value and a blinking text “HIGH”. By default, the function is deactivated;

  • Modbus register: 40205, bit 7;

  • BACnet object: BO7;

• CO2_ALARM_CONFIRM_ENABLE: allows to switch on confirming the CO₂ alarm with any button on the panel. Otherwise, it is only possible to switch off the alarm from the BMS application level;

  • Modbus register: 40205, bit 8;

  • BACnet object: BO63;

• SUBMENU_ICON_DISPLAY_OFF: allows to switch off displaying of the submenu icon. If true, all submenu icons are hidden, even in case when one or more submenus contain active points. The user can enter an active submenu (with at least one active point) and proceed normal operation but its icon is invisible in the main menu display view;

  • Modbus register: 40205, bit 10;

  • BACnet object: BO8;

• PANEL_OFF: allows to switch the panel off. If true, the room panel is inactive. It means that it is impossible to control the room panel locally (access to submenus and parameters configuration is blocked, keypad is deactivated). The LCD display and background illumination are also off. The main menu is not displayed. The room panel works as temperature sensor (or multisensor if either the CO₂ sensor or humidity sensor are built-in). If false, the room panel works in normal mode (functions of local control are active). By default, the panel is on;

  • Modbus register: 40205, bit 11;

  • BACnet object: BO9;

• KEY_PAD_OFF: allows to switch the panel keypad off. If true, the keypad function is deactivated. Single push of any button emits a buzzer sound (if buzzer is activated) and activates the active mode (set background illumination level) but the submenu access is blocked (it is impossible to enter any menu or to change any parameters or settings). The main menu is displayed. By default, the keypad is on;

  • Modbus register: 40205, bit 12;

  • BACnet object: BO10;

• LCD_FLASHING: allows to activate the LCD display flashing. If true, the LCD display flashes with the frequency stored in the LCD_ICON_FLASHING. Flashing brightness level changes from 0% to a maximum value from the parameters: BACKGROUND_LCD_FOR_ACTIVE_MODE, BACKGROUND_LCD_FOR_IDLE_MODE, and BACKGROUND_LCD_FOR_STANDBY_MODE. By default, the LCD flashing is inactive;

  • Modbus register: 40205, bit 13;

  • BACnet object: BO11;

• KEY_PAD_FLASHING: allows to activate the keypad flashing. If true, the keypad flashes with the frequency stored in the LCD_ICON_FLASHING. Flashing brightness level changes from 0% to a maximum value from the parameters: BACKGROUND_KEY_PAD_FOR_ACTIVE_MODE, BACKGROUND_KEY_PAD_FOR_IDLE_MODE, and BACKGROUND_KEY_PAD_FOR_STANDBY_MODE. By default, the keypad flashing is inactive;

  • Modbus register: 40205, bit 14;

  • BACnet object: BO12.
