How to fix low supply air flow in my Komfovent DOMEKT R 400 F Fan?
- M
  Mary CainAug 16, 2025
  If you're experiencing low supply air flow with your Komfovent Fan, here are a few things to check: * Make sure your air filters aren't dirty. If they are, replace them. * Check for any obstructions in your air ducts, dampers, or inlet/exhaust openings. * If you're using VAV air flow control, ensure the pressure sensors are properly connected. If VAV isn't needed, switch to CAV or DCV in the settings. * If the above doesn't resolve the issue, the supply air fan may not be working, and you should contact authorised service.

Why is the heat exchanger icing up in my Komfovent DOMEKT R 400 F?
- D
  dgallagherSep 4, 2025
  If your Komfovent Fan's heat exchanger is icing up, it could be due to: * Malfunctioning antifreeze protection: Check the antifreeze protection settings and ensure any external pre-heater being used is working correctly. * Antifreeze protection switched off: Verify the antifreeze protection settings. If you're not using an integrated or external pre-heater, you can't use a device with a counter-flow heat exchanger when the outside temperature drops below -4 °C.

What causes low heat exchanger efficiency in Komfovent Fan?
- D
  Desiree LewisSep 7, 2025
  If a message indicates low heat exchanger efficiency in your Komfovent Fan, here are some potential causes and solutions: * If air is being extracted through an additional branch (only for DOMEKT R devices), and that's not needed, close the fifth branch. Ensure any air closing damper in the auxiliary extraction duct is completely closed. * If the supply air volume significantly exceeds the extract air volume and this difference isn't required, unify the air flow settings. * If the unit door isn't fully closed, leading to mixed air flows, ensure the door is firmly pressed shut and that the gaskets aren't worn.
