Select the width of the zone between the action of the heating output
and the cooling output. If you select a positive value the heat and cool
outputs cannot be energized at the same time. If you select a negative
value, both outputs can be energized at the same time.
• If a process input is selected the decimal precision will be determined by
the [`dEC1] setting (Input Menu).
