I bought and installed one about a week ago and it's doing a great job of controlling the furnace and temperature. But I discovered that when I press the light bar on the left side of the devices, a quiet and high pitched tone is emitted.
Has anyone else experienced this? Could it be result of a bad component? Bad soldering? When I first opened the thermostat up I wasn't terribly impressed w/ the workmanship of component mounting on the circuit board.
The other question is of course - is this just normal and expected operation of the device? I suppose I could call/email Hunter too! But I do love talking to the "Internet." :)
