4. Setup

4.1 Installation Location

The heating thermostat should be installed on a wall in an area with free air circulation around it. Avoid locations near heat sources, direct sunlight, or drafts, as these can affect temperature readings.

4.2 Wiring Instructions

WARNING: Before proceeding with wiring, ensure that the main power supply to the heating system is completely cut off to prevent electrical shock.

1. After cutting off the power, use a test pen to identify the live and neutral lines of your electrical supply.
2. Connect the live and neutral lines to the designated INPUT terminals on the back of the thermostat.
3. Connect the load line of the underfloor heating actuator to the OUTPUT terminals.
4. Connect the temperature sensor probe to the SENSOR terminals.

• Power Button (⏻): Turns the thermostat on or off.
• Mode Key (M): Cycles through different operating modes (e.g., manual, programmable).
• Up Key (⌃): Increases the set temperature or navigates menu options upwards.
• Down Key (⌄): Decreases the set temperature or navigates menu options downwards.

5.2 Setting Temperature

To adjust the desired temperature, use the Up (⌃) and Down (⌄) keys. The set temperature will be displayed on the screen. The thermostat will then work to maintain the room temperature at your set point.

5.3 Child Lock Function

To activate or deactivate the child lock, refer to the specific instructions in the full user manual provided with the product. This feature prevents unintended changes to settings.

5.4 Power Failure Memory

The thermostat is equipped with a power failure memory function. In the event of a power interruption, the device will automatically resume its last operating settings once power is restored, without requiring manual reset.

6. Maintenance

To ensure optimal performance and longevity of your Walfront Smart Thermostat, follow these maintenance guidelines:

• Cleaning: Regularly wipe the screen and exterior with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the surface and internal components.
• Inspection: Periodically check the wiring connections to ensure they remain secure. If any loose connections are found, ensure the power is off before tightening them.
• Avoid Obstructions: Ensure that the thermostat's ventilation openings are not blocked by dust or objects, as this can affect temperature sensing accuracy.

7. Troubleshooting

If you encounter issues with your thermostat, refer to the following common troubleshooting steps:

• Thermostat not powering on: Check the main power supply to the unit and ensure all wiring connections are secure. Verify that the circuit breaker has not tripped.
• Incorrect temperature reading: Ensure the thermostat is not exposed to direct sunlight, drafts, or other heat sources that could interfere with its internal sensor. Check if the external sensor probe is correctly installed and undamaged.
• Heating system not responding: Verify that the thermostat is in the correct operating mode (e.g., heating mode) and that the set temperature is higher than the current room temperature. Check the wiring to the heating actuator.
• Buttons unresponsive: Check if the child lock function is activated. If so, deactivate it according to the operating instructions.
