| Code | Description | Typical Range | Factory Default | Notes | | :--- | :--- | :--- | :--- | :--- | | | Set Point | -50°C to +50°C | 3°C | The target temperature for the cabinet. | | C1 / HY | Differential (Hysteresis) | 1°C to 15°C | 2°C | The gap between cut-in and cut-out. If Set Point is 3°C and Diff is 2°C, the compressor turns off at 3°C and back on at 5°C (3+2). | | C2 / Od | Output Delay | 0 to 15 min | 2 min | Safety delay to protect the compressor from short-cycling after power loss or cut-out. | | C3 / Ls | Minimum Set Point Limit | - | -50°C | Prevents the user from setting the temp too low. | | C4 / HS | Maximum Set Point Limit | - | 50°C | Prevents the user from setting the temp too high. | | dF / d0 | Defrost Type | 0, 1, 2 | 1 | 0 = Off, 1 = Electric, 2 = Hot Gas. | | d1 | Defrost Interval | 0 to 24 hrs | 6 hrs | How often a defrost cycle initiates. | | d2 | Defrost Duration | 0 to 60 min | 20 min | Maximum time allowed for a defrost cycle. | | d3 | Drip Time | 0 to 15 min | 5 min | Time allowed for water to drain after defrost before fans/compressor restart. | | Fn / F0 | Fan Mode | 0 or 1 | 1 | 0 = Fans run with compressor; 1 = Fans run continuously. | | F1 | Fan Stop Temp | - | 2°C | Stops fans if evaporator temp drops below this point (prevents freezing). | | Appendix | Content | |----------|---------| | A

The is a self-learning energy management controller designed for commercial refrigeration units like glass door coolers (GDC) . It utilizes a "7-day learning matrix" to automatically detect business hours via motion sensors and door openings, switching between high-efficiency "Standby" and standard "Ready" modes to save up to 38% in energy costs. Key Technical Specifications If Set Point is 3°C and Diff is

Used to clear the self-learning matrix if business hours change significantly.

Offsets greater than ±1.5°C indicate a failed sensor. Replace the probe.

It uses two NTC thermistor sensors—one for the appliance cabinet and one for the evaporator coil—providing much more reliable temperature control than single-probe systems. Perishable vs. Non-Perishable Settings:
