• When the "Set" button is pressed briefly, the corresponding para-
meter value is displayed for 15 s. After another 15 s the unit returns
to the Run mode.

than 5 s causes the unit to enter the programming mode.You can alter
the parameter value by pressing the "Set" button and confirm the
new value by pressing the "Mode/Enter" button. The internal sensing,
processing and output functions of the unit continue as if in Run
mode with the original parameter values unless a new value is con-
firmed.

for 15 s.
