3. SECTION 3 - CONTROL MODE CONFIGURATIONS
Depending on Control Mode that was selected, the configuration sub menu windows will query for
the necessary inputs required for the circuit to function. Figure 3.1 presents a flow chart to help
visualize the programming steps and required input for each of the control modes. This section will
present each control mode and guide you through the steps and windows required.
