5.1 Mounting
The XH-W1308 is designed for panel mounting. Cut an opening of 69mm x 28mm in your desired panel. Insert the controller and secure it using the provided screws and nuts.
5.2 Wiring Instructions
IMPORTANT: Ensure all power is disconnected before performing any wiring. Incorrect wiring can damage the device and pose a safety hazard.
5.2.1 AC 110V-220V Equipment Wiring
For controlling AC 110V-220V equipment, use an appropriate AC-DC power adapter (e.g., 12V output) to power the controller. The control equipment is connected to the relay output. Refer to the diagram below:

Figure 4: Wiring diagram for controlling AC 110V-220V equipment. The power adapter (Input: AC110V-220V, Output: 12V) powers the controller. The control equipment is connected to the relay output, and the power adapter is connected to the mains (AC110-220V).
- Connect the AC-DC power adapter's output (e.g., 12V) to the controller's +V and GND terminals.
- Connect the AC-DC power adapter's input to the main AC 110V-220V power source.
- Connect your control equipment (e.g., fan, heater) to the relay output terminals (OUT). The relay acts as a switch for your equipment.
5.2.2 DC 12V/24V Equipment Wiring
For controlling DC 12V or 24V equipment, directly connect the DC power supply to the controller and the control device. Ensure the correct voltage model of the XH-W1308 is used (12V or 24V).

Figure 5: Wiring diagram for controlling DC 12V/24V equipment. A DC 12V/24V power supply is connected to the controller's +V and GND terminals, and the control device is connected to the relay output.
- Connect the DC 12V/24V power supply to the controller's +V (positive) and GND (negative) terminals.
- Connect your control device (e.g., DC fan) to the relay output terminals (OUT).
Sensor Connection: Connect the NTC waterproof sensor to the dedicated sensor input terminals on the main board.
6. Operating Instructions
The XH-W1308 features a digital display and four buttons: SET, ENT, Up (▲), and Down (▼).
6.1 Setting the Desired Temperature
- Short press the SET button once. The displayed temperature value will start flashing.
- Use the Up (▲) or Down (▼) buttons to adjust the desired temperature setpoint.
- Press the ENT button to confirm the setting and exit. If no button is pressed for a few seconds, the setting will automatically save and exit.
6.2 Main Menu Settings (P0-P8)
To access advanced settings, long press the SET button for approximately 5 seconds. The display will show "P0". Use the Up (▲) or Down (▼) buttons to navigate through the parameters (P0-P8). Short press SET to enter a parameter's setting, adjust with Up/Down, and short press SET again to confirm. Short press ENT to return to the previous menu or exit.
| Parameter | Description | Setting Range | Default |
|---|---|---|---|
| P0 | Cooling/Heating Mode | C (Cooling) / H (Heating) | C |
| P1 | Hysteresis Setting (Differential) | 0.1 - 30.0°C | 2.0°C |
| P2 | Upper Limit Setting | -50°C to 110°C | 110°C |
| P3 | Lower Limit Setting | -50°C to 110°C | -50°C |
| P4 | Temperature Correction | -10.0°C to 10.0°C | 0.0°C |
| P5 | Delay Start Time | 0 - 10 minutes | 0 minutes |
| P6 | High Temperature Alarm | -50°C to 110°C (OFF) | OFF |
| P7 | Data Lock | ON / OFF | OFF |
| P8 | Restore Factory Settings | ON / OFF | OFF |
Explanation of Parameters:
- P0 - Cooling/Heating Mode (C/H):
- C (Cooling): The relay activates when the temperature rises above the setpoint + hysteresis, and deactivates when it drops below the setpoint.
- H (Heating): The relay activates when the temperature drops below the setpoint - hysteresis, and deactivates when it rises above the setpoint.
- P1 - Hysteresis Setting: The temperature difference between the activation and deactivation of the relay. This prevents rapid cycling of the controlled device.
- P2 - Upper Limit Setting: Sets the maximum adjustable temperature setpoint.
- P3 - Lower Limit Setting: Sets the minimum adjustable temperature setpoint.
- P4 - Temperature Correction: Allows for calibration of the sensor reading if there's a known offset.
- P5 - Delay Start Time: Sets a delay before the relay activates after a temperature condition is met. Useful for compressors or other devices that require a delay.
- P6 - High Temperature Alarm: If the temperature exceeds this value, an alarm will trigger (if applicable, or display will flash). Set to OFF to disable.
- P7 - Data Lock: Prevents accidental changes to settings. Set to ON to lock parameters.
- P8 - Restore Factory Settings: Resets all parameters to their default values. Set to ON and confirm to perform reset.
7. Maintenance
- Cleaning: Wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Sensor Care: Ensure the temperature sensor is clean and free from debris. Avoid bending or damaging the sensor cable.
- Connections: Periodically check all wiring connections to ensure they are secure.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows "LLL" | Sensor is open circuit or not connected. | Check sensor connection. Replace sensor if damaged. |
| Display shows "HHH" | Sensor is short circuit or temperature exceeds upper limit. | Check sensor for short circuits. Ensure temperature is within operating range. |
| Controller not switching device | Incorrect wiring, P0 mode setting, or hysteresis (P1) too wide. | Verify wiring. Check P0 (Cooling/Heating) and P1 (Hysteresis) settings. Ensure power to the controlled device is correct. |
| Settings cannot be changed | Data lock (P7) is enabled. | Enter main menu, navigate to P7, and set to OFF. |
9. User Tips
- For critical applications, always test the controller's behavior thoroughly before relying on it.
- Consider using a separate fuse or circuit breaker for the power supply to the controller and the controlled device for added safety.
- When setting hysteresis (P1), a larger value will reduce relay cycling, extending its lifespan, but will result in wider temperature fluctuations. A smaller value provides tighter control but increases relay switching frequency.
