How to troubleshoot SystemAir Air Handlers when the fans do not start?
- G
  Gregory AndrewsAug 17, 2025
  If the fans in your SystemAir Air Handlers aren't starting, begin by checking the HMI for any alarms. Next, verify that all fuses and fast couplings are properly connected, including the main power supply and the fast couplings for both supply and extract air fans. Also, ensure that the week schedule is turned ON and running in AUTO mode, as it might be in OFF mode with the airflow set to OFF.

What to do if my SystemAir Air Handlers have low supply air temperature?
- J
  Jennifer LongAug 23, 2025
  If you're experiencing low supply air temperature with your SystemAir Air Handlers, check the display for any alarms. Also, verify if the Defrosting function is active in the HMI screen. Ensure the set supply air temperature in the HMI is correct and that ECO mode is not activated. Check if user modes like HOLIDAY, AWAY, or CROWDED are activated in the HMI or via a hardwired switch. Verify that the temperature sensors are functioning correctly by checking the analogue inputs in the service menu. If you have an electrical re-heater, check if the overheat protection thermostat is active and reset it if necessary. Also, check if the extract filter needs to be changed. If the unit has a re-heater battery connected, consider that very cold outdoor conditions might require it.
