Common issues & fixes
| Error message / symptom | Likely cause | Troubleshooting |
|---|---|---|
| Temperature input error | The controller can't detect the temperature sensor. | Check the sensor cable is plugged into the main module, inspect the cable for damage, and replace the sensor if the wiring is intact. |
| Door open error | The door sensor detects an open door and stops heating. | Make sure the door is latched shut, check that the door magnet aligns with the sensor, and disable "Door Sensor" in settings if one isn't installed. |
| Overheat protection | The safety limit has been exceeded (usually 130°C+). | Locate the temperature sensor near the ceiling, press the small reset button on the sensor housing, and check for adequate airflow. |
| Heater on / no heat | The heater is active but the stones are cold. | Check the circuit breaker for a tripped phase (if 3-phase), and inspect the heating elements — if they don't glow red, they may be burnt out. |
| Heats very slowly | Airflow is restricted inside the heater. | Don't pack the stones tightly; remove and re-stack them loosely so air can pass through the elements. |
| Black screen | The console has no power or data. | Check the data cable connecting the wall screen to the main relay box, then unplug main power, re-seat the cables and restart. |
