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.

If “Disabled” is selected, the user will manually enter these three adjustment values. If you want the instrument to do the auto PID and the P , PI or PID, first select auto disable and enter 0000 for unwanted parameter. i.e. for PI enter 0000 for the rate.
