Factory set. Does not apply when “iF” is 0.
NOTE:
While programming the temperature controller make sure that the enter key is pressed to
enter the desired value. After 10 seconds of inactivity, the display will return to its normal function.
Any setting changes will take effect immediately after the enter key is pressed.

Temperature Control Calibration Accuracy
Once the installation wiring is completed for the chiller control box, check the calibration accuracy of
the temperature control as outlined below:
a. Allow the product temperature to stabilize for a minimum of 15 minutes.
b. Using an accurate electronic thermometer, determine the actual temperature of the solution.
c. If the known product temperature does not correspond with the temperature display, the
temperature control will require an operating parameter correction. This procedure is described in
Sections 3.8 and 3.9, and is adjusted using the “So” code.
