DIGITAL MICROPROCESSOR TEMPERATURE CONTROLLER 

 

The digital microprocessor temperature controller is designed to provide on/off control of refrigerators 

or freezers. The controller also provides a constant readout of the air temperature inside of the unit. A 

touch keypad allows the user to easily select the display units, set point, differential set point, and 

heating or cooling mode. 

 

Please Note: The digital temperature controller has been factory set and tested to 

allow your unit to operate at its designed temperature cycle.  Adjusting the settings on 

the controller will alter these factory settings.  Please allow the unit to operate at 

least 8 hours after the initial startup before making any temperature adjustment. WE 

STRONGLY RECOMMEND YOU CONTACT OUR TECHNICAL SERVICE DEPARTMENT 

BEFORE MAKING ANY ADJUSTMENTS TO THIS CONTROLLER.
