The controller is used to tune the COOL PID values; configure the unit to
continue to run (Indc) or shut down (FLt) in the event of a fault; set the high
(Hit) and low (Lot) temperature limits; and enable/disable auto restart (Auto). If
a temperature limit is exceeded the controller will display an error code, see
Section VI.
NOTE: Serial Communication (SEr) is not operational. Ensure the display
indicates OFF.

CooL is used to adjust the controller's PID values. However,
