Product Description

1.  Introduction:

New Air intelligent controller (KF***0F) can monitor real-time indoor temperature, CO2 concentration. Controller output signal can directly control the startup and speed of fan. 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.  : timing parameter setting

2.  : parameter increase

3.  : parameter reduce    

4.  : setting working mode for controller, press this slightly, the controller will be switched circularly between AUTO ¼ MANUAL ¼ TIMER ¼ POWER OFF.

4. Detailed explanation¼š

1. AUTO: CO2 concentration less than **0ppm (low speed), ******9ppm (middle speed), higher than **0ppm (high speed).

2. MANUAL: set the ventilation machine as OFF(stop)€LOW(low speed)€MED(middle speed)€HIG((high speed))by s  and , and under this mode, the ventilation machine will run according to the setting, wont be affected by CO2 concentration.

3. TIMER (timing mode): run according to set time & speed, can set from Monday to Sunday, 4 period every day, and *8 period total.

4. Timing parameter setting: press   for 2 seconds to enter parameter setting. First enter local time adjust, press   to switch week, hour and minute, the corresponding parameter will flicker, change the number by  and  s; after finishing adjusting local time, press   to enter the first period hour setting on Monday, press   to switch hour, minute, and fan speed, press  and  s to change the number. After finish the setting, press   to enter the second period hour setting on Monday…. Repeat above steps to finish all the *8 period setting. Controller will return to normal working condition and save setting parameter automatically if you wont press any s more than *0 seconds during the setting process.

5. Backlight: CO2 concentration less than **0ppm (green backlight), ******9ppm (yellow backlight), higher than **0ppm (red backlight).
