CONTROL OPTIONS Stepless air flow control with door contact/end switch When the door is closed, the fan runs at low speed (set on the internal 0-10 V potentiometer located inside the outlet grille). When the door opens, the fan runs at high speed (set on an external potentiometer). This control option offers short response time and the best protection. Control kit: PAMP10, external potentiometer SIReDC, door contact or AGB304, limit switch
