Sorry to hear that, not to be the perveyor of the obvious but for everyone else.. ALLWAYS check and make sure your pins are straight when you do a battery change. OMG they charged you 300 for a thermostat? im very sorry

sounds like the fan has been programmed to come on during that time. run through your programming settings and make sure the fan is set to auto for all the times.

controllers more than likely on a memory lockout... kill the power and take the batteries out of it... leave it for 60 seconds and try again... unfortunately you are probably going to have to replace the controller, sorry

Assuming you have the fan switch of your thermostat in AUTO, it sounds like a stuck Fan Relay. If the fan relay is stuck, your fan will continue to run as long as there is line voltage being fed to your unit. This relay could be an independent component or it could be an integral part of your control board. Have an experienced, qualified service technician check it out.
