By default the PI reference is set for a digital reference level set in P-45.
When using an Analog reference set P-44 = 1 (analog) and connect reference signal to analog input 1 (T6).
The default settings for proportional gain (P-41), integral gain (P-42) and feedback mode (P-43) are suitable for most HVAC
and pumping applications.
The analog reference used for PI controller can also be used as the local speed reference when P15=1.
NOTE
Further information on configuring the PI controller for typical feedback applications; please refer to the Advanced User Guide.
