T/S not working. Upon arrival I found the thermostat was working properly. However the program was not correct. I programmed the cooling for 9:00 am to 9:00 pm 69* and 9:00 pm to 9:00am 74*. Due to high electric bill I changed the fan mode from on to automatic. For the weekend I programmed 9:00am to 6:00 pm 69*. The temperature was 69* when I arrived and cooling properly. Thermostat is a Braeburn.
