About midnight, the thermostat gave off a high buzz, with a high note warning it was coming. It lasted for 25 minutes. At first I thought it was batteries. Took the thermostat off the wall. No batteries. All electronic. Any suggestions??????

Yes:
1) Don't use homeowners hub; they're free-riding on Usenet 2) Provide sufficient information in your post to be useful for diagnosis - Manufacturer and Model identification for thermostat - Type of HVAC system (home, commercial, Heat only, Heat/Cool) 3) RTFM. If you didn't keep it (or don't have it), you can likely find it with a simple google search.Join the Discussion
