Fig. 7 Controller operation In normal operation the controller displays cabinet temperatures in degrees C (default) or user-selected degrees F. Degrees C temperatures are displayed to 1 decimal point. refrigeration system energized Rocker buttons to the right of the temperature display control all programming functions. The controller is pre-programmed with a -25 C (-13 F) set point which provides a compressor cut-in at -23 C (-9 F) and cut-out at -25 C (-13 F).
Controller security The controller panel can be locked to prevent inadvertent or intentional programming changes. In locked mode, the controller will display cabinet temperature and cut-out set point only. To lock the controller 1.

When the cabinet interior temperature reaches +2.2 C (+4 F) above the controller set point, the probe signals the controller to turn the refrigeration system on.
