| 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. | eliwell sb655 c manual

The maximum duration allowed for a single defrost cycle. This acts as a safety timeout. Fan Management ( F Menu)

The storage temperature has exceeded the safe maximum threshold for longer than the permitted delay time. Check for door leaks, compressor failures, or heavy product loading. Always prioritize safety and consult a professional if
