Help, I Can't Turn the Speed Down!

Calibration Procedure for Air Flo D2646PVs and D3555PVs

If you're having trouble with an Air Flo controller that won't let you turn the speed down, you might have recalibrated the minimum run speed by accident. To set the minimum run speed to a more reasonable value, just follow this simple procedure:

  • Make sure MODE SWITCH is set to PAUSE.
  • Make sure the POWER SWITCH is set to ON.
  • Turn BOTH SPEED DIALS to the desired minimum speed settings.
  • Press and hold the BLAST BUTTON for 3 seconds.
  • Release the BLAST BUTTON to lock in the desired minimum speed settings.
  • The PAUSE/AUX light will blink once to confirm the settings are locked in.
