The parameters are set as follows in the factory: Proportional range maximum (2@0%) Reset time maximum (1. 9 min) ¥ 45 The controller thus displays a predominantly proportional action. Three potentiometers are provided on the control unit (PER 22) for special adjustments: P@ for adjusting reset time P2 for adjusting the proportional range P3 for delaying the setpoint (remains at left-hand stop) If the setscrew is turned counter-clockwise: the reset time is shortened (I component is increased) the proportional range is diminished (P component is reduced) Control parameters Start of adjustment P max.
