Parameter Descriptions

Default Display

This parameter determines whether the OTC25 P’s display shows the Setpoint or the actual temperature by default. Regardless of the selection made here, the operator can observe the other value by momentarily pressing the

Parameter Key. This will cause the alternate value to be displayed for five seconds.

Display Offset

Display Offset is adjustable from -126 to 126° F (-70 to 70° C). It can be used to provide limited adjustment of the displayed temperature as a compensation for offsets between the true temperature and the temperature seen by the thermocouple.
