32. Keep stepping by pressing the ▲ button as long as you
see this sub-menu item:
means: the hysteresis of the high limit value. Here you can
define a numerical value which provides the hysteresis of
the high limit value (HL) by having added to and
subtracted from it. Consequently, the actual hysteresis is
twice the value defined here.
