the blinking digit:

,

,

,

,

,

,

Sequence of operations
32. Keep stepping by pressing the ▲ button as long as you
see this sub-menu item:

. HH ( H igh H ysteresis)
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.

ENTER button.
