0,5 K
0,7 K

1.5 K
Interval between the switch-
off point (set point value) and
the re-switch on point (Set
point value – hysteresis).
The hysteresis prevents
constant switch on/off.
Feedback of hysteresis
controlled with switch point
None
0,1 K/min
0,2 K/min
0.3 K/min
The feedback causes a
gradual decrease in the
Hysteresis over time.
This increases control
accuracy.
The hysteresis is equivalent to
the programmed value for
each switch-off and is
gradually reduced by the
feedback process. The
hysteresis can reduce to 0
over prolonged periods of
switch-off.
At the next switch-on, it is
reset to the configured value.
