My vision pro TH8110U thermostat screen was blinking on/off (bright/dim). It also made faint clicking sounds as it blinked. It would not respond to touch on any part of the screen. I flipped the breaker switch off, then on (it had not tripped).

The screen now responds, the system seems to be operating normally, and there are no indicators on screen indicating any issues. I replaced the three triple A batteries "just in case." ( the entire havoc system and thermostat are 8 months old). Any idea why the screen was behaving that way? We were out several hours, and the house was warm, the system was not cooling. After resetting the breaker, the system is cooling.

Leave well enough alone and wait to see if it happens again?
