    A sash sensor then measures the vertical opening of the fume hood sash. As an option, the Model FHC50 can use a sidewall sensor to monitor or trim the face velocity when calculated from sash position and exhaust flow rate.

  • Page 12: Useful User Information

    Yellow Light The yellow light is on to indicate that the Model FHC50 controller is muted or in setback mode. The LCD display will read “Setback” or “Mute” at the top of the screen to indicate the meaning of the yellow light.
