The most critical feature for managing a "repack" (restoring or updating the controller's configuration) is the use of the or Copy Card . This allows technicians to bypass manual manual entry of dozens of parameters.
: The manual covers SB655, SB655/C, and SB655/S models, which share similar digital output configurations. Digital Outputs (DOL)
Let’s walk through a real-world scenario:
The Eliwell SB655C features a simple and intuitive interface:
: 5 relays, 2 PWM outputs, and 2 x 0-10V analog outputs. eliwell sb655 c manual repack
Features include automatic summer/winter changeover, Adaptive cooling (without battery), and Free Cooling/Free Heating functionality. 2. Understanding "Repack" (Parameter Loading/Cloning)
When the first parameter code appears, use the arrows to navigate to the password parameter ().
: 5 dedicated sensor inputs configured to read NTC, 4-20mA pressure transmitters, or voltage-based signals. Terminal Layout and Electrical Wiring
Cause: Storage space temperature has exceeded the parameter limit for a time greater than ALd . The most critical feature for managing a "repack"
: The manual defrost and mode functions can be explicitly enabled or disabled via parameters Ui21 (Mode selection) and AIE (Manual defrost) to prevent unauthorized manual overrides. Technical Specifications for Repacking
Unlike modern controllers that can be programmed via USB or smartphone apps, the SB655 C often requires manual entry via the keypad.

The serves as a centralized management unit for air conditioning systems, supporting up to two independent refrigeration circuits. It is designed to handle compressors of various types— Scroll , Semi-Hermetic , or Screw —up to 4 power output steps, including advanced capacity management.

While "repack" is not an official product designation, the controller itself is highly regarded for its versatility in HVAC/R applications.
| Parameter | Name | Typical Setting (R404A Freezer) | Why it matters | | :--- | :--- | :--- | :--- | | | Set Point | -10°F / -23°C | The target temperature when running. | | r0 | Cut-in (Diff) | 36 PSI (or 5°F) | Mechanical switch logic: SP + r0 = Cut-in pressure. | | r1 | Cut-out (Safety) | 0 PSI | The low-pressure safety lockout. | | OdO | Output delay | 3 minutes | Protects compressor from short cycling. | | Ot | Probe type | P30 (for NTC) / Pr1 (4-20mA) | Most common error: Wrong setting here = "- - -" on screen. | | rtr | Relay type | CL (Cooling) | Changes from heating mode to cooling mode. | | ALu | Low pressure alarm | 10 PSI | Alerts before the safety trips. | | P2P | Probe 2 function | DEF (Defrost) | Tells the unit to use temp probe to end defrost. |
