New Air intelligent controller (KF-800M) can monitor real-time indoor temperature,
CO2 concentration. Controller output signal can directly control the startup and speed of ventilator. It can be widely used in residential, commercial and industrial applications, and can effectively improve air quality, create a healthy, comfortable, energy-efficient living and working environment.
2. 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 between “AUTO － MANUAL － TIMER － POWER OFF”.
3. Display explanation:
Indoor temperature CO2 concentration
Heating switch mode
4. 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’t 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 –concentration 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 – 600ppm). Controller will return to normal working condition and save setting parameter automatically if you won’t 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 “local time adjust”, 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’t 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).
