set point and an input variable.
• [``Ht] select reverse action, so that output 2B responds when the input
signal is less than the set point.
• [``CL] select direct action, so that output 2B responds when the input
signal is more than the set point.
[Ot2b]
This prompt appears only if channel B output is something other
than a process output (99__-___F-____).
