Why is there reduced airflow in my SystemAir Fan?
- D
  Daniel GriffithAug 2, 2025
  If your SystemAir Fan experiences reduced airflow, several factors could be responsible. First, check the display for any alarms. Verify the airflow settings in the control panel and the week program settings. Ensure that none of the digital inputs 1–3 (DI 1–3) are active and set to off. Confirm auto mode is not reducing airflow due to external sensor readings. Inspect and replace filters if needed. Clear any obstructions from diffusers/louvers, fans, and the heat exchange block. Lastly, check for blockages in the building's air intake and roof exhaust, and examine duct runs for damage or dust buildup.

  William TranAug 8, 2025
  If your SystemAir Fan doesn't start, begin by checking the display for any alarms. Verify the fuse for the main power supply in the building's distribution box and ensure all quick connectors are securely connected within the unit, specifically those for the supply and extract air fans. Confirm that the week program is in ON mode and not set to OFF with airflow set to OFF. Also, check if any of the digital inputs 1–3 (DI 1–3) are active and set to off, as this can force one or both fans to stop depending on the setup.

Why is the supply air temperature low in my SystemAir Fan?
- T
  Taylor JacksonAug 26, 2025
  If you notice a low supply air temperature from your SystemAir Fan, start by checking the display for any alarms. Verify the set supply air temperature in the control panel. Check the analogue inputs in the service menu to verify that the temperature sensors are working correctly. Ensure that the Home/Leave function is disabled (DI 7). Check if the overheat protection is triggered. Verify that digital input 4 (DI 4) is not set to off. Check if the extract filter needs to be changed. At very cold outdoor conditions an electrical pre-heating battery might be necessary. Check the balance between the supply and extract air.
