I have a Honeywell Energy Star Chronotherm IV Plus T8601D2019 2 0135 and my wall unit cut off. I tried flipping the breakers, checked the inside and outside unit and can not figure out what is going on. I took the unit off the wall to check the batteries and release it does not have any. Any ideas would be appreciated. My name is Robert Bliven 704-307-0242 rmbliven@gmail.com
