- Heating Not Working:
- Ensure the thermostat is in heating mode and the set temperature is higher than the current room temperature.
- Check the wiring connections to your heating system (boiler, electric floor, water floor).
- Verify that the "Open Window Detection" (Option 11) or "Anti-freeze Function" (Option 05) is not active and preventing heating.
- Wi-Fi Connectivity Issues:
- Ensure your Zigbee gateway hub is powered on and connected to your home Wi-Fi network.
- Check that the thermostat is within range of the Zigbee gateway.
- Repeat the Wi-Fi connection steps (Section 4.3) if necessary.
