My new GE through wall unit seems very inconsistent. While set on 76, sometimes it allows room to get up to 85 degrees before turning on, and other times it only gets up to 79. Also, when cooling down, it usually will kick off when it reaches around 73 but sometimes it will cool the room down to 65. I'm taking my room temperatures on a thermometer right next to the ac unit. I'm just wondering why it's not consistent in it's cooling behavior, and if this is normal.

Hello all, I am in the process of replacing the thermostat on a split type ac unit. I bought a standard programmable thermostat but after taking the old thermostat apart I can see that the set ups are very different. On the current thermostat, the white goes to a screw on the thermostat board with X1 printed on the board. Blue goes into a screw on the thermostat board with X2 printed on the board. And those are the only two that go directly to the thermostat board. Behind the thermostat inside the wall, there are two wires that are like the blue and white wires (Meaning they have the single cooper metal stick coming out of them). And two fatter wires that don't look like the other thermostat wires (Meaning they have a bunch of tiny wires bunched up). The yellow wire with the single copper end has the blue fatter wire wrapped around it. And the green wire with the single copper end has the yellow fatter wire wrapped around it. The red and brown thermostat wires aren't plugged into anything. I have a standard Honeywell programmable thermostat that has letters for each color (Except for the brown cable). I hooked all them up but the ac doesn't come on (Note that I did not try and hook up the two fatter wires during this process). I have not been able to see a set up like this online so I was hoping someone can assist with this Any assistance would be appreciated. If you need more info then please let me know and I will provide it. Below is a picture of the current set up. Thank you!
