Understanding the Eliwell SB655 C is essential for refrigeration technicians and industrial maintenance teams who manage temperature-controlled environments. While these units are known for their longevity, finding a comprehensive "repack" or condensed guide for the SB655 C can be difficult since many legacy manuals are out of print.
This article serves as a consolidated technical reference for the Eliwell SB655 C, covering installation, wiring, and parameter programming.
If you are manually reprogramming a unit (repacking it) without a backup file, you must ensure the fundamental parameters match the system's physical requirements.

2. Probe Selection (PbC / Pr1)
3. Calibration (CA1)

For refrigeration technicians and maintenance engineers, the Eliwell SB655 series represents a staple in commercial and industrial temperature control. When dealing with legacy units or systems that have undergone significant repairs, you may encounter the term "Manual Repack."
This post breaks down what a manual repack entails for the SB655 C controller, why it is necessary, and the critical parameters you need to know.
The manual shows 11 terminals. Here is the cheat sheet for the most common setup (230V AC supply with a pressure transducer).
Terminal Block (Left to Right):
The "Gotcha": If you are using a 4-20mA pressure transmitter, you must bridge terminal 7 (V+) to terminal 8 (Signal) via a 500-ohm resistor? No. Actually, check the manual specifics, but modern transducers just use 2 wires. Pro tip: Most SB655C failures happen because techs wire the pressure transducer backward. Red = 7, Black = 9, White = 8.
