The Setpoint is the target temperature the controller maintains inside the cold room.
| Label | Description | Notes | | :--- | :--- | :--- | | | | | | SEt | Temperature Setpoint for the controlled medium. | - | | diF | Differential (Hysteresis). The compressor stops at SEt and restarts at SEt + diF . | Value cannot be zero | | HSE | Maximum allowable Setpoint value. | Prevents user error | | LSE | Minimum allowable Setpoint value. | Prevents user error | | Operating Mode | | | | HC | Regulator operating mode. Set to C for cooling (chiller) or H for heating (heat pump). | Caution: Changing this may require reconfiguring other parameters | | Defrost Settings | | | | tdF | Type of defrost (e.g., Electrical, Hot Gas). | Configure based on system | | EdF | Defrost interval between cycles. | - | | MdF | Maximum duration for a defrost cycle. | Safety cut-off | | Fan Management | | | | FSt | Fan stop temperature (when the evaporator is very cold). | Optimizes system efficiency | | FOn / FOF | Differential temperatures to cycle fans on/off. | - | | Alarm Parameters | | | | ALu / ALL | High and low temperature alarm thresholds. | Defines the acceptable temperature range | | PAL | Delay time for an alarm to be triggered after a threshold is crossed. | Prevents nuisance alarms |

The is a microprocessor controller primarily used for managing centralised air-conditioning units, including chillers and heat pumps with up to two circuits and multiple compressor stages. Core Manuals & Technical Documentation
: Features automatic summer-winter changeover and heat pump deactivation at very low temperatures. Energy Efficiency The Setpoint is the target temperature the controller

Check the door seals, ensure the condenser coils are clean, and verify that the compressor relay is successfully outputting voltage. To help narrow down your specific issue, let me know: The compressor stops at SEt and restarts at SEt + diF
If settings reset after power fluctuations, check main supply voltages for spikes and ensure grounding wires do not bleed current into the neutral terminal. To help tailor this guide, let me know:
