It helped with learning which wires and what they are used for. I have 5 wires. 1.white wire connected to aux. Yellow hooked to y. Green hooked to g. Blue hooked to o. Red hooked to r. Now where does the blue wire go on the nest thermostat? Also does the white wire go on the w on the nest thermostat? Thanks for your help and if you or someone could answer the 2 questions. Again thanks.
Okay I tried hooking it up like this. I hooked the white to w. Yellow to y. Green to g. Blue to OB. Red to r. The heat pump came on outside, but the inside unit did not come on. By the way I live in a trailor and I live in Georgia if that helps. When the Honeywell thermostat was hooked up the inside and outside units both worked when the heat or cool air was on. I am not sure if it was right but it was like that when I bought the trailor brand new. Thanks for your help. If I can’t get this right I might have to call a pro. Thanks again for your help
