I Incorrect operation due to ignoring instruction will cause harm or damage. [. . . ] - This is the operating function to control the amount of external air flow so that the CO2 level is controlled within the set level by detecting the indoor CO2 level. - The initial CO2 level is set to 1000ppm, and can be changed by the user. - This function operates when auto ventilation operation (Additional operation) is selected during air conditioning or heating operation. But if there is no CO2 sensor and damper actuator on the AHU, the auto ventilation operation cannot be selected. - When the mixing temperature during the heating operation is below the set value (5°C), preheating device automatically operates. The preheating device and mixing temperature sensor must be installed on AHU for this to operate automatically.
