CO2 Sensor (Optional)

A CO₂ sensor is an optional equipment in the Control Point panel. It is marked with a letter C in a product code, for example: CP-HC (means the panel is equipped with a temperature, humidity, and CO₂ sensors). The CO₂ sensor's configuration data is available in the following parameters or in the iSMA Configurator:

CO2_SENSOR: indicates a current CO₂ value with offset;

• Modbus register: 30303;

• BACnet object: AI6, property: Present Value;

CO2_OFFSET: allows to set an offset value for the CO₂ sensor (correction to the CO₂ sensor's value). The default value is 0;

• Modbus register: 40306;

• BACnet object: AI6, property: 4205;

CO2_FILTER: allows to set a filtering value for the CO₂ sensor (expressed in seconds). The default value is 10 seconds;

• Modbus register: 40309;

• BACnet object: AI6, property: 4003;

CO2_NAME: allows to set a unique 4-letter name for a CO₂ sensor;

• Modbus registers: 40314, 40315 (each for two letters of the name);

• BACnet object: AI 6, property: Description Property.

Configuration of CO₂ Sensor on Display

CO2_CONFIGURATION: allows to activate or deactivate the CO2 sensor:

• ACTIVE: activates or deactivates the sensor;

  • Modbus register: 40318, bit 0;

  • BACnet object: AO6, property: 4200;
