13-C.Select either Start on Setpoint or Stop on Setpoint by pressing CHANGE CHOICE. Press ACCEPT to continue.

•Start on Setpoint will start a program when the setpoint condition is met. The program continues to run even if the condition falls back within the setpoint limits.

•Stop On Setpoint halts the program if the setpoint condition falls back within the setpoint limits and starts again if the limits are exceeded.

13-D.Highlight the desired channel to trigger from, then press SELECT. 13-E.Press either HIGH CONDITION or LOW CONDITION.
