  • Check battery level or USB power connection.
  • Ensure the thermostat and receiver are within the 30m RF range.
  • Verify the receiver has power.
• No Wi-Fi connection:
  • Ensure your Wi-Fi router is working and the signal is strong where the thermostat is located.
  • Confirm you are connecting to a 2.4GHz Wi-Fi network (5GHz is not supported).
  • Restart your router and the thermostat, then try connecting again via the app.
• Heating/Cooling system not turning on/off:
  • Check the wiring connections at the receiver unit (refer to Section 2.5).
  • Ensure the thermostat is in the correct mode (Heating/Cooling) and the set temperature is appropriate.
  • Verify the 'Output On' icon is displayed on the thermostat.
• Inaccurate temperature reading:
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources.
  • Use the temperature calibration feature in the app to adjust the reading if necessary.
