SANYO control system

The SANYO control system surpasses other proportional only control systems available today. The digital PID(proportional, integral, and dif- ferential) control maximizes unit performance by maintaining a ± 0.5° C deviation in leaving chilled water temperature from setpoint. Proportional controls typically can only maintain a ± 1° C deviation from setpoint. The controller's innovative design also incorporates the ability to start and stop the system chilled/hot and cooling water pumps. During shutdown these pumps are sequenced to insure a complete dilution cycle.

The leaving chilled water temperature is measured every five seconds and fuel input is changed according to the gradient of the leaving chilled water temperature curve. System temperatures, setpoints, and opera-

tional records are displayed along with indicator lights for the chiller, pumps and burner.

The SANYO control system offers its users self-diagnostics by constantly monitoring the chiller's status and will automatically shut the chiller down should a fault occur. The cause of shutdown will be retained in memory and can be displayed for immediate operator review. The controller's memory will also retain and display the cause of the last three system fault conditions. This method of retaining fault conditions is extremely useful for maintaining an accurate record of unit performance and fault history.
