Okay, so I have a VE-300 thermostat that is about 1yr old now. Recently it has started to have the alarm go off and repeat over and over to "set time point". I have reset everything on it and it will be happy for 3-4 hours then the alarm goes off again. Sometimes though it will go off every 10 minutes for awhil. Does anyone have any suggestions? Maybe I am completely missing something on it.

I have checked and temps are still great.
