1 review for Fireye NXF4000 Combustion Efficiency Control

  1. David Marks

    So many things to say about Fireye NXF4000. I have not seen a controller that is so easy to learn and operate. It makes parallel position less intimidating due to its simplicity and intuitive menu system. Performance is off the charts… love it!
