If you're unable to set your thermostat, it could be due to various reasons such as a lockout feature being enabled, a low battery, or issues with the thermostat's wiring or firmware.

For firmware issues, consulting the manufacturer’s instructions for a reset or firmware update could be helpful. If these steps don’t work, you might need to contact a professional.
