Troubleshooting
If you encounter issues with your Avidsen thermostat, refer to the following common troubleshooting steps:
- No Display/Unit Not Responding: Check if the batteries are correctly inserted and have sufficient charge. Replace batteries if necessary.
- Incorrect Temperature Reading: Ensure the thermostat is not located near heat sources, cold drafts, or direct sunlight.
- Heating/Cooling Not Activating: Verify that the system's power supply is on. Check wiring connections. Ensure the thermostat is in the correct operating mode (heating/cooling) and the set temperature is appropriate.
- Programming Issues: If programs are not executing as expected, re-enter programming mode and verify all settings. A factory reset (using the 'RESET' button) may resolve persistent programming issues, but will erase all custom settings.
