  1. Pump errors (E5): Often caused by blockages or faulty AD valve readings.
  2. Moisture sensor discrepancies (ONCE/TWICE): Calibrate or replace the sensor if moisture levels are inconsistent.
  3. Relay connection failures (GZG): Verify wiring integrity at the tab relays.
  4. Gas valve activation issues (PCK): Confirm propane supply and valve functionality.
  5. Heater malfunctions (3TIMES/4TIMES): Check heater resistance and controller outputs.
  • Power Configuration: Supports electric (2700W/5400W) and gas modes
  • Temperature Range: 5°C to 70°C (operational)
  • Diagnostic Modes: 6-step motor/pump/heater test sequences
  • NFC Module: For wireless control and diagnostics
  • Moisture Sensing: Thresholds at 30 (high) and 255 (low)
  • Valve Control: AD valve range 11~255 for pump regulation
