The controller controls temperature using a Proportional-Integral-Derivative
(PID) algorithm. It is designed with an easy to use operator interface.
This key is used to start and stop the chiller.
This key is used to navigate through the controller displays, to
make changes and to save changes once they are made. It is
also used to clear error codes.
This key is also used to navigate through controller displays.

• Place the optional GFCI breaker located on the rear to the up position.
• For ThermoFlex900 through 10000s, place the circuit protector located
on the rear to the on ( I ) position. The display will indicate a series of
upward scrolling bars (
).
• For ThermoFlex15000 and 24000s, the display will indicate a series of
upward scrolling bars (
