Controls the electric heating elements or hot gas solenoid valves.
The lists several alarm codes on the display. Here is how to interpret them:
| Code | Description | Range | Default | |------|-------------|-------|---------| | | Defrost type | 0=Electric, 1=Hot gas | 0 | | di | Defrost interval | 0 – 99 | 6 | hours | | dE | Defrost duration | 0 – 99 | 30 | minutes | | dS | Defrost stop temperature | -50 – 110 | 8.0 | °C | | dP | Post-defrost drip time | 0 – 99 | 5 | minutes | | Fd | Forced defrost after power-on | 0=No, 1=Yes | 0 |
is a highly versatile, parametric electronic controller belonging to the Eliwell Energy Flex family . Explicitly engineered for , this device manages up to two independent refrigerant circuits and a maximum of four compressor capacity steps . It provides commercial and industrial HVAC operators with precise capacity modulation, balancing operational run-times across diverse machinery types.
Sets whether defrost uses electric heaters, hot gas inversion, or basic off-cycle air ventilation. Defrost Interval Time 0 to 120 hours Frequency of automatic defrost initialization. dEt Defrost Endurance Time (Max Duration) 1 to 250 min eliwell sb655 c manual
At 4 a.m. the cooler read 4.1°C and hummed steadily—no alarm. The compressor cycled normally, with healthy run times and restful pauses. The brief warm spikes had vanished; the logging showed stable readings with no unexplained gaps. In the morning, the blood-bank manager came down bleary-eyed and relieved. Marco handed over the manual with the pages marked where he had made changes, and explained each adjustment in plain terms: cable degraded → intermittent probe signal; controller responded correctly to noisy input; tweak anti-short-cycle and filter settings to ignore transients.
: Controls up to 4 compressors or 2 refrigerant circuits with 2 compressors per circuit. Inputs/Outputs
The Eliwell SB655 C is a microprocessor-based temperature controller designed to regulate the temperature of a system or process. It's widely used in refrigeration, air conditioning, and heating applications, as well as in industrial processes such as food processing, pharmaceuticals, and chemical processing.
These control how the compressor behaves. Controls the electric heating elements or hot gas
Note: Additional parameters for defrost (if using an external SSR/relay) and digital inputs exist but are rare on the base SB655 C model.
The is a high-performance electronic controller designed primarily for commercial refrigeration, cold storage, and HVAC applications. Known for its reliability and precise temperature regulation, this device manages compressors, defrost cycles, and evaporator fans to ensure optimal climate control.
Navigating the Eliwell menu allows you to customize the cooling cycles for your specific inventory needs. How to Modify the Setpoint (Target Temperature)
