2. Connect the Live (L1) and Neutral (N1) wires of your electric heating system (heating wire/mat) to the designated output terminals.
3. Connect the external NTC temperature sensor to terminals 9 and 10. This sensor is crucial for accurate floor temperature measurement.
4. Ensure all connections are secure and properly insulated.
5. Mount the thermostat into the wall box using the provided screws.

The central ring allows for temperature adjustment by sliding a finger.

4.1 Basic Operation

• Power Key: Press the power icon (top right) to turn the thermostat ON or OFF.
• Temperature Display: The central LED display shows the current room temperature or the set temperature.
• Setting Temperature: Slide your finger along the illuminated ring around the central display to adjust the desired temperature. The display will show the new setpoint temporarily.
• Heating Light: An indicator light (usually below the power key) illuminates when the heating system is active.

4.2 Operating Modes (Patterns)

The thermostat supports different operating patterns to suit your needs:

• Home Pattern: Designed for comfort when you are at home. Typically set to a higher temperature (e.g., 20°C). Activate this mode by touching the 'Home' icon (bottom left).
• Departure Pattern: Designed for energy saving when you are away. Typically set to a lower temperature (e.g., 15°C). Activate this mode by touching the 'Departure' icon (bottom right).

Refer to the full manual for advanced settings, including programming schedules and sensor calibration, if available.

5. Maintenance

The Wengart WG502 thermostat requires minimal maintenance.

• Cleaning: Wipe the screen and casing with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the surface.
• Inspection: Periodically check the thermostat for any signs of damage or loose connections. If any issues are found, consult a qualified electrician.
• Software Updates: If the thermostat supports Wi-Fi connectivity, check the manufacturer's website or app for any available firmware updates to ensure optimal performance and security.

6. Troubleshooting

If you encounter issues with your Wengart WG502 thermostat, try the following troubleshooting steps:

• No Power/Display Off:
  • Check the main power supply to the thermostat.
  • Ensure the circuit breaker for the heating system is not tripped.
  • Verify all wiring connections are secure.
• Heating Not Activating:
  • Ensure the thermostat is powered ON and the desired temperature is set higher than the current room temperature.
  • Check if the heating light indicator is on.
  • Verify the external NTC sensor is properly connected and functioning. A faulty sensor can prevent heating.
  • Confirm the heating system (e.g., heating mat) itself is operational.
• Incorrect Temperature Reading:
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or other heat sources that could affect its internal sensor.
  • If using an external sensor, check its placement and connection.
  • Calibrate the temperature if necessary (refer to advanced settings in the full manual).
• Unresponsive Touch Screen:
  • Turn the thermostat off and on again (power cycle).
  • Ensure the screen is clean and dry.

If these steps do not resolve the issue, contact a qualified technician or Wengart customer support for assistance.
