Default factory setting

• The device comes with below default setting:

| ACFA-250T| ACFA-350T| ACFA-500T
---|---|---|---

Airflow m³/h

| SPEED 1| 80| 100| 105
SPEED 2| 100| 130| 185
SPEED 3| 145| 180| 270
SPEED 4| 175| 245| 350

Operation Instruction

• The device has two controller panels, Panel 1-Daily simple settings, Panel 2-Advance parameters settings. Positions are as followed:

• Speed control: Press to switch from Speed 1 to 4, speed 1 is “traveling mode”, when switch to this mode, the ventilator turns to super low speed.

• Fan Boost: Press to switch to the boost speed for 30 minutes, and then return to original status.

• Filter timer reset: After 60 days running, when the filters is needed cleaning or replacement, the light will be illumined. After replacement or cleaning, hold this button for long time to reset the filter timer.

• Error Indicator: When it’s illumined, the fan or the sensors are in error, the indicator lights off after error cleared.

• Bypass: When bypass is on, it will be illumined. When bypass is off, then the light is off, bypass opening temperature: Outdoor 17 to 21 degree Celsius.

• Humidity control : when the ventilator is running, if indoor humidity over 75%RH, ventilator will enter the boost speed, until the humidity lower than 75%RH.

• CO2 control (optional): By connecting a CO2 sensor to it, when the ventilator is running, if the indoor CO2 value over 1000PPM, ventilator will enter the boost speed, until the CO2 value lower than 1000PPM.

• Defrost: When defrost mode is activated, it will be illumined. Defrost mode activated temperature: Outdoor less than or equal to –5degree Celsius.
  Note: In order to prevent frost inside the device, the ventilator is in automatic adjustment and cannot be operated when in defrost mode.

• The above values are default values, user can change the default values by optional touch screen controller or Modbus system.

• Air volume setting: Press “Speed” to select speed 1 to 4, then press “+” or “-” to set air volume for the selected speed, after 4 speeds setting done then press “Speed” again to save setting or it will be automatically saved after 15 seconds without operation.

• Balance rate setting: Long press the “Speed” button for 6 seconds when the digital display shows “LPL”, press “+” or “-” to set the air volume bal-ance rate of supply and exhaust.

1. The value is 0, then supply airflow is equal to exhaust airflow.

2. The value is 1 to 50, then supply airflow is larger than exhaust airflow.
   Note: the larger the value, the smaller the exhaust airflow.

3. The value is –50 to –1, then supply airflow is less than exhaust airflow.
   Note: the larger the absolute value, the smaller the supply air flow.

• Right and left installation switching: Long press the “+” key for 6 seconds when the digital display shows “PLP”, press “Speed” button to switch between the right and left installation modes. The number 1 represents the right type, and the number 2 represents the left type.
  Note: The setting must be consistent with the installation form, otherwise, it will affect the use of the ventilator.

• Restore factory settings : press the “+” and “-” buttons at the same time, the air volume and air volume balance rate will return to the factory default settings.

• RS485 address setting: Long press the “-” key for 6 seconds, press “+” or “-” to set the RS485 address of the ventilator for centralized control.

Maintenance

Maintenance

• Filter replacement

  • It’s recommended that all filters be inspected every 3 months and replaced once or twice a year, or be replaced when the “filter alarm” indicator on the control panel illumined. Otherwise the performance or energy efficiency of the ventilator might be affected.

• Step 1: Press the two buckles at the top to remove the maintenance panel.

• Step 2: Take out the SA/RA/bypass filter

• Step 3: Put the filters back in place after cleaning or replacing, re-install the maintenance panel, then reset the time of the filter alarm (Refer to instruction 4.3).

• Drain pipe inspection
  It’s recommended that the condensate drain pipe should be inspected once or twice a year, preventing the leakage due to poor drainage.

• Air duct, air inlet/outlet inspection
  It’s recommended that the air duct, air inlet/outlet should be inspected regularly, preventing the abnormal ventilation of the equipment due to block- age.

• Heat exchanger cleanness
  The heat exchanger needs cleanness and maintenance regularly, it’s recommended that the heat exchanger should be cleaned or maintained every 3 years. Please contact our service center if needed.
