The Eliwell SB655 C is a highly reliable electronic controller widely used in commercial refrigeration, catering, and HVAC systems. Known for its precise temperature regulation and durable construction, this device ensures food safety and optimal equipment performance.
If no evaporator probe is connected, the defrost cycle initiates exactly every dit hours and runs for exactly dEt minutes.
is built for HVAC flexibility. According to the product documentation on Eliwell , key specs include: eliwell sb655 c manual
: A "Copy Card" can be used to quickly upload or download parameter maps between multiple controllers of the same model. Common Alarms : AL1 : Low-temperature alarm on probe 1. E1/E2 : Probe errors (shorted or interrupted). Opd : Open door alarm triggered by a digital input.
: Common codes such as E1 (cell probe error) or E2 (defrost probe error) indicate shorted or interrupted sensors. The Eliwell SB655 C is a highly reliable
The controller manages complex defrost cycles using dual-probe readings:
Features configurable digital outputs (DOL/AOL) for controlling external components like compressors or fans. is built for HVAC flexibility
If configuration parameters become corrupted or if you need to deploy identical settings across multiple units, use these administrative overrides: Performing a Hard Factory Reset Power down the controller completely. Hold down the and DOWN keys simultaneously. While holding the keys, restore power to the controller.
Insert the controller into a standard 71x29 mm panel cutout. Secure it using the provided click-on side brackets.

| Parameter | Description | | :--- | :--- | | | Temperature Setpoint : The target temperature to be maintained. | | diF | Differential : The difference in temperature between the compressor stopping (at SEt) and restarting (at SEt + diF). For example, if SEt = 5°C and diF = 2°C, the compressor will stop at 5°C and restart at 7°C. Note: the value 0 cannot be assumed. | | HSE | Higher Set : The maximum permissible setpoint value (to prevent user errors). | | LSE | Lower Set : The minimum permissible setpoint value. | | HC | Operating Mode : Configures the main output to operate in C (Cool/Cold) or H (Heat/Hot) mode. | | OSP | Offset Set Point : A temperature value added to the setpoint when an "Economy" function is enabled. | | OdO | Door Open Activation Delay : The delay time before the digital input (door switch) triggers an action (e.g., switching off loads). | | Ont / OFt | Compressor ON/OFF Time : Used for safety in the event of a faulty sensor probe. Ont is the ON time in a duty cycle; OFt is the OFF time. | | H00 | Probe Type Configuration : Sets the type of sensor connected. 0 = PTC; 1 = NTC. |
