Proportional Band, Output 2
Select the proportional band for PID output 2. If set to
[```0] it func-
tions as an on/off control, and the switching differential is determined by
the
[HYS2] value (Output Menu). Decimal precision is determined by the
[`dEC1] or [`dEC2] setting (Input Menu).
[Pb2A] This prompt appears only if [CntL] (Global Menu) is not set to
