touch screen intelligent controller

 INTRODUCTION:

KF-800A is our newest model of air quality controller, it's intelligent and with touch panel, (remote control function is optional).It's the best choice for high-end commercial and residential buildings. It's able to real-time monitor indoor temperature and VOC concentration. Built-in air quality sensor can real-time detect indoor organic volatile gases; output signal of air quality controller can control the startup and speed of ventilator. It can effectively improve air quality; create a healthy, comfortable, energy-efficient living and working environment.

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)\HIGH((high speed))by buttonsand , 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. Remote control: operation method & function of buttons on remote control is the same as that of touch buttons on ventilator controller.

7. Backlight: blue color backlight, the backlight turns on when operate buttons and or remote control, the backlight automatically turns off if without operation of buttons or remote control more than 10 seconds.
