  If you're experiencing reduced airflow with your SystemAir Fan, here are some things to check: Examine the display for any alarms. Verify the fan speed setting on the control panel and the week program settings. Ensure none of the digital inputs 1–3 (DI 1–3) are active and set to off. Inspect the filters, diffusers/louvres, fans, and heat exchange block. Also, check for any clogs in the building's air intake and roof unit (exhaust). Look for visible damage or dust/pollution buildup in duct runs, and ensure diffuser/louvre openings are clear.

Why is the supply air temperature low in my SystemAir SAVE VSR 500 Fan?
- K
  Krystal BrewerSep 8, 2025
  If you're experiencing low supply air temperature with your SystemAir Fan, consider the following: Check the display for any alarms. Verify the set supply air temperature in the control panel. Inspect the analogue inputs in the service menu to ensure the temperature sensors are functioning correctly. Check if the overheat protection thermostat is still active. Ensure that digital input 4 (DI 4) is not set to off. See if the extract filter needs to be changed. If outdoor conditions are very cold, an electrical or water pre-heating battery might be necessary. Finally, check the balance between the supply and extract air.

Why is airflow reduced in my SystemAir Fan?
- B
  billymorganSep 9, 2025
  If your SystemAir Fan is producing reduced airflow, it could be due to several reasons. First, check the HMI for active alarms, as some can reduce airflow. The unit might be in defrost mode, which reduces fan speed or shuts down the supply air fan. If the outdoor air temperature is below 0°C, the outdoor airflow compensation function might be active. Also, ensure that a temporary user mode like AWAY or HOLIDAY isn't activated. Check digital inputs for CENTRAL VACUUM CLEANER and COOKER HOOD. Other potential causes include airflow settings in the HMI, week schedule settings, clogged filters, dirty diffusers/louvres, dirty fans and heat exchange block, clogged air intake, damage or pollution build-up in duct runs, and diffuser/louvre openings.
