Also refer to: Configuration Mode and Linear Output.
Overlap/Deadband
Defines the portion of the primary and secondary proportional bands over which both outputs
are active (called Overlap), or neither is active (called Deadband). This is adjustable in the
range -20% to +20% of the sum of the two proportional bands. Positive values = Overlap,
negative values = Deadband.
