Buttons function 1. button: timing parameter setting 2. button: parameter increase 3. button: parameter reduce 4. button: setting working mode for controller, press this button slightly, the controller will be switched circularly betweenAUTO MANUAL TIMER POWER OFF. 3. Display explana4. Detailed explanation 1. AUTO (auto mode): high speed: CO2 concentration exceeds the setting concentration value of 300ppm; middle speed: CO2 concentration exceeds the setting concentration value of 100ppm; low speed: CO2 concentration exceeds the setting concentration value; stop: CO2 concentration is below the set concentration value. 2. MANUAL: set the ventilator as OFF(stop)LOW(low speed)MED(middle speed)HIG((high speed))by buttons and , and under this mode, the ventilator will run according to the setting, won¬H be affected by CO2 concentration. 3. TIMER (timing mode): run according to set time & speed, can set from Monday to Sunday, 4 periods every day, and 28 periods in total. 4. Automatic mode Cconcentration value setting when the ventilator starts: under the auto mode, press or button for one second, it will appear CO2 concentration setting value and flicker, then press and buttons to change the number (from 350 ¡§C 600ppm). Controller will return to normal working condition and save setting parameter automatically if you won¬H press any buttons more than 10 seconds during the setting process. 5. Timing parameter setting: press button for 2 seconds to enter parameter setting. First enter ¡ãlocal time adjust¡À, press button to switch week, hour and minute, the corresponding parameter will flicker, change the number by and buttons; after finishing adjusting local time, press button to enter the first period hour setting on Monday, press button to switch hour, minute, and ventilator speed, press and buttons to change the number. After finish the setting, press button to enter the second period hour setting on Monday. Repeat above steps to finish all the 28 periods setting. Controller will return to normal working condition and save setting parameter automatically if you won¬H press any buttons more than 10 seconds during the setting process. 6. Backlight: CO2 concentration less than 500ppm (green backlight), 500-799ppm (yellow backlight), higher than 800ppm (red backlight).

o3 gas sensor is widely used in water disinfection, food processing and purification, food storage and preservation, medical and health, and household disinfection and purification. In ozone applications, a certain concentration of ozone is an important parameter to ensure disinfection, energy conservation and pollution prevention. But as If the concentration of ozone in the environment is too high, it will cause harm to the human body. Therefore, it is very necessary to effectively monitor the concentration of ozone. The transmitter uses electrochemical technology to measure O3 concentration, and the reaction is quick and sensitive, which can reliably detect ozone concentration. degree. o3 gas sensor product uses 485 communication, standard ModBus-RTU communication protocol, communication address and baud rate can be set, the farthest pass The letter distance is 2000 meters. The equipment is 10-30V wide-voltage power supply, and the enclosure has a high degree of protection, which can adapt to various harsh conditions on site.
