Hysteresis The value of the hysteresis indicates how much the pressure may
rise (in mbar) before the vacuum valve is opened. Setting range is
between 1 and 50 mbar (only by using valve controlled pumps Rota-
vac valve control, Rotavac valve tec, or House vacuum source).
Timer Setting of the timer to shut down the process. Setting range is be-
