I installed a 7 day programmable thermostat for my mom at the end of fall last year. I thought I had everything hooked up correctly until she needed the A/C. I don't know why this is racking my brain so much. But I just can't seem to figure out how to wire it. The furnace and the fan work. I messed around with it today and I got the A/C running using the setup pictured. The a/c did run, but the fan on the a/c unit turned off and I could hear the compressor still going (is that normal?) it's only 72 out. I realized I didn't pull the number 3 jumper, so I pulled it. It's working, but since there wasn't a wiring diagram for my unit, I just wanted to have a seasoned pros take a look at what I did. Feel free to make fun if I did something stupid.
Oh and that is orange hooked up to the yellow.
