Hysteresis:
The hysteresis keeps the switch-
ing state of the outputs stable if
the system temperature varies
about the preset value.
With the system temperature
rising, the output switches when
the switch-on point has been
reached (SP1). With the system
temperature falling, the output
does not switch back until the
switch-off point (rP1) has been
reached. The hysteresis can be adjusted: First the switch-on point is
set, then the switch-off point with the requested difference.
Window function:
The window function enables
the monitoring of a defined
acceptable range.
When the system temperature
varies between the switch-on
point (SP1) and the switch-off
point (rP1),
switched (window function/NO)
or not switched (window func-
tion/NC).
The width of the window can be
set by means of the difference between SP1 and rP1. SP1 = upper
value, rP1 = lower value.
