8. Error Codes
| Code | Meaning | Solution |
|------|---------|----------|
| --- | Sensor open circuit | Check sensor wiring or replace probe |
| HHH | Temperature >120°C or sensor short | Verify sensor, check for short |
| LLL | Temperature <-50°C | Sensor disconnected or extremely low temp | I understand you're looking for information on the
8. Alarm Codes & Troubleshooting
| Display | Meaning | Solution | |---------|---------|----------| | E1 | Sensor open circuit | Check sensor wiring or replace sensor | | E2 | Sensor short circuit | Replace NTC sensor | | EE | EEPROM error | Return to factory (reset not possible) | | AL-H | High temp alarm | Temperature > F6 setting | | AL-L | Low temp alarm | Temperature < F7 setting |
Other issues:
- Unit won’t turn on → Check power supply (must match model)
- Relay clicks but device off → Load exceeds 10A → Use contactor
- Temp fluctuates wildly → Sensor in wrong position or F3 too low
6. Parameter Table (F-code)
| Code | Function | Default | Range | Description | |------|----------|---------|-------|-------------| | F1 | Heating differential | 2.0°C | 0.1–15°C | Heating stops when PV ≥ SV | | F2 | Cooling differential | 2.0°C | 0.1–15°C | Cooling starts when PV ≥ SV+F2 | | F3 | Temperature calibration | 0.0°C | -10–10°C | Adjust sensor deviation | | F4 | Compressor delay | 0 min | 0–10 min | Anti-short cycle delay | | F5 | High temp alarm | 110°C | Off, SV–120°C | Alarm if PV > F5 | | F6 | Low temp alarm | -50°C | -50–SV | Alarm if PV < F6 | | F7 | Working mode | 0 | 0 or 1 | 0=Cooling priority, 1=Heating priority | | F8 | Restore defaults | 0 | 0 or 1 | Set to 1 to reset all settings | | F9 | Temperature unit | 0 | 0 or 1 | 0=°C, 1=°F |
Key features (typical for STC-600 series)
- Digital display showing actual temperature and setpoint.
- Relay outputs for heating and cooling (often dual-role or single relay + alarm).
- Temperature sensor input (commonly NTC thermistor or PT100/NTC variant).
- Adjustable hysteresis, control differential, and alarm thresholds.
- Calibration offset and sensor type selection.
- Compact panel-mount form factor with simple button interface.
