Switching Functions
10.1
Hysteresis function
The hysteresis keeps the switch state of the outputs stable if the meas-
urement values (of pressure, temperature, and level) fluctuate around
the desired value. When system pressure is rising, the output switches
after it reaches the corresponding switching point (SP). If system pressure
falls again, the output switches back only if the reverse switching point
(rSP) has been reached. (Refer to menu options FunC, SP, rSP.)
