Hello,
First update the panel to eliminate any known issues and take advantage of enhancements that have been implemented. You can find a guide for your panel at this link.
After this has been completed, power cycle the panel and check if the schedule is adhering to the next interval temperature.
Failing this, you may need to factory reset the thermostat after removing it from the account.
Please let me know if you see any successful results after the power cycle or if you continue to have trouble, I am here to help!
