Controller Operation - Performance Plus
In normal operation, the controller displays product temperature in degrees C (default) or user-selected degrees F.
The controller is pre-programmed with a 6 C (42.8 F) set point. COMP displays when the compressor is running.
If this set point does not meet your specific application needs, instructions for changing the set point are found
below.
Note: Follett presets its refrigeration system to hold product temperature at approximately 6 C (42.8 F).
