I'm sorry to hear you're having an issue with our thermostat, but I'd like to help you out. Do you have any messages on the screen when that happens? Also, did you check if that isn't caused by the Bacteria prevention feature? Check out this article to be able to identify the Bacteria Prevention icon on your thermostat: https://bit.ly/3p0oB7P.
Since I haven't heard from you in a while, I'll have to close this thread. Should anything else come up, please open another thread and we'll take it from there. Have a good one and stay safe!
