5. Setup and Wiring
Proper wiring is crucial for the safe and correct operation of the XH-W3001. Refer to the diagram below and follow the instructions carefully.
Figure 5.1: XH-W3001 220V Wiring Connection Diagram.
Wiring Instructions:
- Power Input (220V): Connect the two wires from your 220V AC power supply to the terminals labeled 'N' (Neutral) and 'L' (Live) on the controller. These are typically the two leftmost terminals.
- Load Output (220V): Connect the device you wish to control (e.g., a heater or fan) to the output terminals. One wire from the load connects to the 'N' terminal (Neutral) of the output, and the other wire connects to the 'L' terminal (Live) of the output. Ensure the load's voltage matches the controller's output.
- Sensor Probe: Plug the waterproof NTC10K temperature sensor probe into the dedicated two-pin connector on the controller. The probe can be placed in the environment where temperature needs to be measured.
- Grounding: If applicable, ensure proper grounding for your power supply and load according to local electrical codes.
Warning: Always ensure power is disconnected before making any wiring connections to prevent electrical shock.
6. Operating Instructions
Initial Power-Up:
After correct wiring, apply power to the controller. The LED display will show the current measured temperature. The red indicator light will illuminate when the output is active.
Setting Temperature Parameters:
The XH-W3001 has two main parameters: Start Temperature (P0) and Stop Temperature (P1).
- Set Start Temperature (P0):
Press and hold the UP button for approximately 3 seconds. The display will flash. Use the UP or DOWN buttons to adjust the desired start temperature. Press the UP button again to confirm and exit, or wait 5 seconds for automatic exit. - Set Stop Temperature (P1):
Press and hold the DOWN button for approximately 3 seconds. The display will flash. Use the UP or DOWN buttons to adjust the desired stop temperature. Press the DOWN button again to confirm and exit, or wait 5 seconds for automatic exit.
Working Modes (Heating/Cooling):
- Heating Mode: If the Start Temperature (P0) is set lower than the Stop Temperature (P1), the controller operates in heating mode. The output will activate when the current temperature drops below P0 and deactivate when it reaches P1.
- Cooling Mode: If the Start Temperature (P0) is set higher than the Stop Temperature (P1), the controller operates in cooling mode. The output will activate when the current temperature rises above P0 and deactivate when it reaches P1.
Advanced Settings:
To access advanced settings, press and hold both UP and DOWN buttons simultaneously for approximately 3 seconds. The display will show 'P0'. Use the UP or DOWN buttons to cycle through the parameters (P0-P6). Press the UP button to enter the selected parameter's adjustment mode, then use UP or DOWN to change its value. Press UP again to save and exit the parameter, or wait 5 seconds for automatic exit.
- P0: Heating/Cooling Mode (Set Start Temp) - (As described above, this is the primary start temperature setting)
- P1: Stop Temperature (Set Stop Temp) - (As described above, this is the primary stop temperature setting)
- P2: Temperature Correction: Adjusts the measured temperature by a certain offset (e.g., to calibrate the sensor). Range: -10.0℃ to 10.0℃.
- P3: Delay Start: Sets a delay time (in minutes) before the output activates after the temperature condition is met. Range: 0 to 10 minutes.
- P4: High Temperature Alarm: Sets a temperature threshold. If the current temperature exceeds this value, an alarm may be triggered (visual or audible, depending on implementation).
- P5: Low Temperature Alarm: Sets a temperature threshold. If the current temperature falls below this value, an alarm may be triggered.
- P6: Data Lock: Locks the settings to prevent accidental changes.
Reset to Factory Settings:
To restore all settings to their factory defaults, power off the controller. Then, press and hold both the UP and DOWN buttons simultaneously while powering the device back on. The display will show '888' indicating a successful reset.
7. Maintenance
- Cleaning: Gently wipe the device's exterior with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Probe Care: Ensure the sensor probe is clean and free from debris for accurate readings. The stainless steel probe is waterproof, but avoid unnecessary physical damage.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
8. Troubleshooting
- Display is blank:
Check power connections. Ensure the voltage supply is correct (220V). - Temperature reading is inaccurate:
Verify the sensor probe is correctly connected and placed in the desired measurement area. Use the P2 (Temperature Correction) setting to calibrate if necessary. - Controller not switching output:
Check if the Start (P0) and Stop (P1) temperatures are set correctly for the desired heating or cooling mode. Ensure the load is properly wired and functional. Check if P3 (Delay Start) is active. - Settings cannot be changed:
Check if P6 (Data Lock) is enabled. Disable it to adjust settings.
