The error that results from the measurement of the Process Variable may be
positive or negative since it may be greater or smaller than the Setpoint. If a
positive error should cause the instrument output to increase (i.e. cooling), it would
be called Direct Acting. If a negative error should cause the output to increase
(i.e. heating), it would be called Reverse Acting.
