Unable to connect with outside sensor, bought this unit from Lowe's a month ago. About 4 days ago to outside temp locked at 20 degrees. Multiple times trying to reset the unit failed. Called the online support, unit manufactured date is over a year old so it's not under warranty - Great! Bought it a month ago and manufacture date is over a year old?! They wanted to sell me replacement parts, but didn't want to buy parts since the reliability is sketchy at best. Well it work for a month.
