NOTE
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 P-15=1.

Motor Thermistor Connection
1 : + 24 Volt
The motor thermistor should be connected between terminals 1 and 4 as shown. A
setting of P-15 where Digital Input 3 is programmed for ‘External Trip’ must be used.
The current flow through the thermistor is automatically controlled to prevent a
failure.
