GC500 Series Cold Controls
Constant Differential Universal Replacement
The GC500 series constant differential controls always maintain the same difference
between on and off temperature over the range of the control. The knob varies the operating
temperature while the differential remains constant. These controls are ideally suited for
“Frostfree” refrigerators and conventional refrigeration units. Universal mounting hardware
insures these controls will replace wide range of controls.
