The Monitoring Controller Pairing with the Main Unit

Pairing
The monitoring controller works collaboratively with the main unit through a Bluetooth wireless connection, can be paired with LIFAair smart air purifiers within certain distance.

1. Press and hold the monitoring controller ON/OFF button to turn it on.

2. Slide anticlockwise on the touch circle of purifier main unit to let the main unit blink green slowly, with one finger press and hold icon on the touch circle for over 5 seconds until the green light flashes rapidly. The main unit will then enter pairing mode for 30 seconds.
   Note: When pairing, the main unit must be in standby mode (green light slowly flashing; when the main unit flashes white, it has been successfully paired with the controller).

3. Press and hold on the controller, press to select”Purifier Pairing”, then press to confirm.

4. Press to move selection box to”Yes”and press  to confirm, the monitoring controller and main unit will enter auto pairing mode.

5. After the pairing is successful, the main unit indicator light will turn white, and the monitoring controller will display “Paired”. The icon will appear at the top of the secondary display. If pairing is unsuccessful, please repeat the above steps.

The Monitoring Controller Testing Items

Your smart air purifier monitoring controller can monitor PM2.5, CO2 and TVOC concentration. When paired with LIFAair smart air purifiers, it can automatically control purifier main unit and maintain PM2.5 concentration in a healthy range. It can also monitor temperature and humidity. The monitoring controller will monitor air quality. There are six levels: good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and hazardous. American standards will be more stringent.

PM2.5 measurement

In the main interface press and  to switch to”PM2.5″interface.
The Chinese standard requires PM2.5 level to be below  35µg/m3. American standard requires PM2.5 level to be under 12µg/m3. It takes about 40 seconds for the value to stabilize.

CO2 measurement

In the main interface press and  to switch to”CO2″interface. CO2 concentration will display on the monitoring controller, ≤1000ppm is good. When the concentration is over the standard level, it is recommended to open window for ventilation.  It takes about 40 seconds for the value to stabilize. The average CO2 concentration in outdoor air is about 400ppm.

TVOC measurement

In the main interface press and to switch to”TVOC”interface.
According to current standards, AQI (air quality index) measurement doesn’t account for TVOC. Thus, when the monitoring controller displays”good”, it doesn’t indicate TVOC is under standard level. It takes about 40 seconds for the value to stabilize.

Note: The monitoring controller uses a semiconductor sensor to measure TVOC, it cannot replace professional instruments.

TVOC is divided into five levels:

Good: Moderate: Unhealthy: Very unhealthy: Hazardous:

Temperature measurement

In the main interface press and  to switch to”TEMP”interface.
It displays the temperature at which the purifier main unit is located.
Note: To enable this function, please ensure the monitoring controller is connected with LIFAair purifier main unit.
Humidity measurement

In the main interface press and  to switch to”HUM”interface.
It displays the relative humidity at which the purifier main unit is located.
Note: To enable this function, please ensure the monitoring controller is connected with LIFAair purifier main unit.

Short Time and Continuous Monitoring of the Monitoring Controller

Press and hold , the controller will continuously monitor air quality and will display for 5 minutes. The”Test” icon will blink on the secondary display screen. Press to exit this mode at any time during this process.

Note: After pairing with the unit (main unit indicator light is white), the controller will regularly monitor air quality and auto-control the operation of the main unit, despite of what aforementioned mode is selected.

How to Operate the Monitoring Controller

To enable full autonomous operation, please ensure the monitoring controller is connected to the main unit.

1. Control the main unit: Press to enter speed mode selection interface (paired with the main unit), press and   to move selection box and press to select different purification mode.
   Purifier Off: Power on/off purifier.
   Smart Mode: According to real-time indoor air quality, the monitoring controller will auto-adjust the main unit’s fan speed (recommended mode).
   Manual Mode: Manually adjust the fan speed of the main unit; the fan speed will be held at set value.
   Night Mode: Fan will run at ultra-low noise level, to ensure a comfortable sleeping environment. Fan speed will remain at constant speed.
   Turbo Mode: Maximum fan speed, rapid purification.
   Anti Allergy: The main unit will continue to run at a specified fan speed and will not be affected by PM2.5 concentration during this period. It is recommended to enable this function during flu or pollen season.

2. Press and hold  to enter settings interface, press  and to select and press  to confirm modification, then press again to return to main interface.

3. Filter checking
   LIFAair series smart purifiers all implemented advanced filter life-span calculation algorithm, it accurately calculates filter usage. Press to enter filter monitoring interface, press and to separately view each filter’s life status. The filter should be replaced when the monitoring controller indicates the filter’s capacity is less than 5%.
   After cleaning or replacing the filter, please press to enter filter reset interface. Select”Yes”to reset, the monitoring controller will then restart the monitoring process.

CO2 Calibration

How to calibrate CO2:

CO2 sensors have been pre-calibrated. If there appears to be a systematic error, proceed to recalibrate.
Calibration method:
Place the monitoring controller outdoors, ensure sufficient ventilation. After 10 minutes, turn on the monitoring  controller and perform two”Continuous measurement” procedures. After the second”Continuous measurement”, wait for 3 minutes. Press and hold  to enter main interface, press and   to move selection box to”CO2 calibration”and press  to enter selection interface, then press , to select”Yes” and press again to calibrate CO2 value to 400ppm.

Note: If maloperation occurs, please select”Factory Settings”in the main menu to restore to default factory settings.

Warning

Main unit tilting:
Do not tilt main unit during operation. If it is tilted over 45 degrees, the monitoring controller screen will display such warning, and the main unit will stop operating until it is restored back to upright position. The warning icon will then also disappear.

Note:

• When the monitoring controller is disconnected from its power supply, after each monitoring cycle the monitor will automatically enter standby mode.
  The main and secondary display will be off, until the main power supply is connected.

• In standby mode, if the monitoring controller is paired with the main unit, the monitoring controller will still control and operate the main unit, despite the display being off.
