Parameter Setting Adjustments
Table 1 shows how to alter the universal control program to fit your specific model and application.
Locate your model type, and then change the parameter settings to the values shown. For instructions on changing parameter settings, see “Adjust Parameters” section.
*FREEZER MODELS ONLY: Be sure to change duA before adjusting any other parameter setting.
After changing the programming, be sure to adjust the set point for the application per table 2.

TOAM-72 ONLY — Third Defrost Probe
Verify the third defrost probe’s operation. If operating correctly reuse the probe.
If operating incorrectly, remove a tooth (see fig. 4) from a provided defrost probe.
For an additional defrost probe, in the USA or Canada, please contact our parts department at 800-424-8783 or PartsInquiries@TrueMfg.com. For all other locations, please see the contact information.
