5. The temperature controller increases the temperature to the next
step. A new step is created either when a new stage turns on or
when a variable stage reaches maximum speed. When the second
case occurs, the step value is not incremented and the PF-6 displays

6. Repeat steps 2, 3 and 4 until the last stage on the controller is
reached.
7. When the last stage has been calibrated, the temperature controller
increases the temperature to 120°F to calibrate the over-opening
step. Use the adjustment knob to manually adjust the opening value
on each PF-6 unit for the over-opening step – CLO to close, OPN to
open, AUT to retrieve the previously calibrated position, and OFF to
finish adjusting.
