  • Black Out Alarm: Activated after power failure, indicated by flashing defrost LED and 'bLo' display.
  • Door Open Alarm: Triggered if door remains open beyond set time, indicated by flashing 'dA' label.
  • High Condensation Temperature Alarm: Activated when condenser temperature exceeds threshold, indicated by 'HtC'.
  • High Pressure Alarm: Triggered by excessive condenser temperature, indicated by 'HP'.
  • Probe Alarms: Faulty probes trigger specific alarms ('E0', 'E1', 'E2').
Factory Parameters Reset
Parameters can be reset to factory settings by pressing the On/Sby/Enter key three times during the test phase, indicated by 'rLd' on the display.Parameters List
The document includes a comprehensive list of configuration parameters for measurement inputs, compressor adjustment, defrost settings, alarm management, and fan adjustments. Each parameter has a default, minimum, and maximum value, allowing customization of the device's operation.
