Functions
If your Series 16 controller was ordered with this option, you may select either of two setpoints for your
process. The second setpoint can be enabled only by an external switch or signal, according to your
ordering specifications. The "F2" LED on the front panel will illuminate when a second setpoint is selected. If
you do not know how your Series 16 was configured, refer to the ordering code shown later in this manual.
