Dead Band B

Select the width of the zone between the action of the channel B
heating output and cooling output. If you select a positive value the heat
and cool outputs cannot be energized at the same time. If you select a neg-
ative value, both outputs can be energized at the same time.

• If a process input is selected the decimal precision will be determined by
the [dEC2] setting (Input Menu).

[db`b] This prompt appears only if [Pb1b] and [Pb2b] are set higher than
[```0] and one channel B output performs heating action and the other
performs cooling action.
