3. Setup Instructions
- Unpack the Device: Carefully remove the Xetron STC-1000Pro controller and its components from the packaging.
- Connect the Sensor: Ensure the temperature sensor is fully inserted into its dedicated port on the side of the controller. A loose connection can lead to "ERR" display.
- Position the Sensor: Place the temperature probe in the environment where temperature monitoring and control are required. Ensure it is not directly exposed to heating or cooling elements to get an accurate reading.
- Connect Heating/Cooling Devices:
- Plug your heating device (e.g., heat lamp, heating mat) into the socket labeled "HEATING".
- Plug your cooling device (e.g., fan, chiller) into the socket labeled "COOLING".
Important: The maximum output for each socket is 10A at 240VAC. Do not connect high-power equipment exceeding these limits.
- Power On: Plug the controller's main power cord into a standard 230V AC power outlet. The display will illuminate, showing the current temperature (PV) and other settings.

4. Operating Instructions
The STC-1000Pro features a simple 3-button interface: SET, UP (▲), and DOWN (▼).
4.1 Display Overview
- PV (Present Value): Displays the current measured temperature.
- SV (Set Value): Displays the target temperature you wish to maintain.
- Csp (Cooling Start Point): The temperature at which the cooling device will activate.
- Hsp (Heating Start Point): The temperature at which the heating device will activate.
4.2 Setting the Target Temperature (SV)
- Press the SET button once. The SV value will flash.
- Use the UP (▲) or DOWN (▼) buttons to adjust the target temperature.
- Press SET again to confirm and save the setting, or wait a few seconds for it to save automatically.
4.3 Advanced Parameter Settings
To access advanced settings, press and hold the SET button for approximately 3 seconds until the display changes to show parameter codes.
Figure 9: Diagram illustrating parameter settings. This image shows the relationship between TS (Temperature Set-point), CD (Cooling Differential), HD (Heating Differential), Csp (Cooling Start Point), and Hsp (Heating Start Point).
Use the UP (▲) or DOWN (▼) buttons to navigate through the parameters. Press SET to enter a parameter's value, then use UP (▲) or DOWN (▼) to adjust, and SET again to save.
| Parameter | Description | Range | Default |
|---|---|---|---|
| TS (Temperature Set-point) | The desired target temperature (same as SV). | -40 to 110 ℃ / -40 to 230 ℉ | Varies |
| CD (Cooling Differential) | The difference between the cooling start point (Csp) and the set temperature (TS). Cooling activates when PV ≥ TS + CD. | 0.1 to 30 ℃ / 0.1 to 54 ℉ | 2 ℃ / 3.6 ℉ |
| HD (Heating Differential) | The difference between the heating start point (Hsp) and the set temperature (TS). Heating activates when PV ≤ TS - HD. | 0.1 to 30 ℃ / 0.1 to 54 ℉ | 2 ℃ / 3.6 ℉ |
| PT (Protection Time) | Compressor delay protection time (in minutes) for cooling mode only. Prevents frequent compressor cycling. | 0 to 10 minutes | 3 minutes |
| CA (Temperature Calibration) | Adjusts the temperature reading to match an external reference thermometer. | -10 to 10 ℃ / -18 to 18 ℉ | 0 ℃ / 0 ℉ |
| CF (Unit Switch) | Switches between Celsius (℃) and Fahrenheit (℉). | C / F | C |
| HA (High Alarm) | Sets the upper temperature limit for the alarm. | TS to 110 ℃ / TS to 230 ℉ | 110 ℃ / 230 ℉ |
| LA (Low Alarm) | Sets the lower temperature limit for the alarm. | -40 ℃ / -40 ℉ to TS | -40 ℃ / -40 ℉ |
After adjusting parameters, press and hold SET again for 3 seconds to exit the advanced settings menu and return to normal operation.
5. Maintenance
- Cleaning: Disconnect the power before cleaning. Wipe the controller's surface with a soft, damp cloth. Do not use abrasive cleaners or immerse the main unit in water. The temperature probe can be cleaned with water.
- Storage: Store the device in a dry environment within the temperature range of -20 ℃ to 75 ℃ (-4 ℉ to 167 ℉) to ensure the longest possible lifespan.
- Sensor Care: Ensure the temperature sensor cable is not pinched or damaged. A damaged sensor can lead to inaccurate readings or error messages.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| "ERR" displayed on screen | Temperature sensor not fully inserted or damaged; temperature exceeds measurement range. | Ensure the sensor is fully inserted into its port. If the issue persists, the sensor may be faulty and require replacement. If the temperature is outside the -40 to 110 ℃ range, the controller will display "ERR". |
| Alarm sounds and bell icon appears | Current temperature (PV) has exceeded the set high alarm (HA) or fallen below the low alarm (LA) threshold. | Check the environmental conditions. Adjust HA/LA settings if necessary. The controller will disable all outputs in fault alarm mode to protect equipment. |
| Heating/Cooling device not activating | Incorrect temperature settings (TS, CD, HD); compressor delay protection (PT) active; device not properly plugged in; device malfunction. | Verify TS, CD, and HD settings. Wait for the PT delay to expire in cooling mode. Ensure devices are securely plugged into the correct outlets. Test heating/cooling devices independently. |
| Inaccurate temperature reading | Sensor placement; temperature calibration (CA) offset. | Relocate the sensor to a more representative area. Use the CA parameter to calibrate the reading against a known accurate thermometer. |

8. Safety Warnings and Precautions
- Electrical Load: Do not connect equipment with a total power consumption exceeding 10A (2400W at 240V) to each outlet. Overloading can cause damage to the controller and connected devices, and poses a fire hazard.
- Voltage Compatibility: Ensure the controller's voltage (230V) matches your local power supply.
- Water Exposure: While the probe is waterproof, the main controller unit is not designed for immersion. Avoid exposing the main unit to direct water spray or submersion.
- Sensor Integrity: Always ensure the temperature sensor is fully and securely inserted. A short-circuited or damaged sensor will trigger a fault alarm and disable outputs for protection.
- Children and Pets: Keep the device and its cables out of reach of children and pets to prevent accidental damage or injury.
- Ventilation: Ensure adequate ventilation around the controller to prevent overheating.
