Table 26 Leaving Fluid Temperature Setpoints
The leaving chilled water temperature is not the same as the ice termination setpoint. The
ice termination setpoint is based on entering chilled water temperature. Therefore, the ice
termination setpoint, minus temperature drop across the evaporator while in the ice
making mode, equals the leaving chilled water temperature.

safety controls (solution freeze point is nominally 10'F above refrig temp cutout).
