Hysteresis:
The hysteresis keeps the switch-
ing state of the outputs stable if
the system temperature varies
about the preset value.
When the system temperature is
rising, the output switches when
the switch-on point has been
reached (SP1); when the system
temperature is falling again, the
output switches back when 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 accept-
able range.
When the system temperature
varies between the switch-on
point (SP1) and the switch-off
point (rP1), the output is switched
(window function/NO) or not
switched (window function/NC).
The width of the window can be
set by means of the difference
between SP1 and rP1. SP1 = upper value, rP1 = lower value.
