Automated Production PF-6 Mode D'emploi page 19

Drop Mode:
To use drop mode, set internal switch #8 to ON. The PF-6 maintains the
inlet opening at the value of the last controller stage as the temperature
rises above the last reference point temperature. When the temperature
reaches "temperature of the last reference point + over-opening band-
width" , the inlet is opened to the over-opening percentage. When the
temperature drops by 0.5°F, the inlet returns to the opening of the last
controller stage.
