Instruction

1. AUTO Mode: CO2 concentration<500ppm, Fan is in LOW Speed. 500ppm<CO2 concentration<799ppm, Fan is in Med Speed. 800ppm<CO2 concentration, Fan is in HIGH Speed

2. MANUAL Mode: Setting the fan as OFF, LOW, MED,HIGH by button  and . In MANUAL MODE,the fan will run according to the setting, wont be affacted by CO2 concentration.

3. PROGRAMMING Mode: Programming mode: Controlller will be run according to the set time & speed(7 days, 4 time periods each day).

4. Programming Setting: Long press  button for 2 second and then enter setting parameter interface. Firstly, local time calibration.
