Tell me if this is what you have or not please, I do not understand about the '5 wire'. Please elaborate.
Please attach a well focused, close up photo of the wiring diagram glued inside the service panel,you can use the paper clip icon at the right end of the toolbar at the top of this dialog box,Include a picture of the thermostat wire connections to the printed circuit board in the same area.
If there is no paper clip icon, look for the '+attach files' link at left of your send button.
I can mark it up with trouble shooting instructions. You will need a multi meter ($30 at a hardware store) and some experience working with appliances, let me know a lot about your skill sets in those regards.
We can go from there.
I must be very direct here. This is close to worst wiring mess that I have ever seen, not only are the thermostat connections non standard, but the free hand mark ups on the thermostat will not work either... the system controls will need to be rewired from *scratch.
To do that I will the photo's I asked for in my previous post.
I will give those photo's I need a look, if I can see a quick fix I will provide it, if not I will ask for a very substantial extra... in the range of $150, or I can opt out at your option.
Get me those pictures, we can go from there.
I will wait until I get the pictures, we can go from there.
I also need photo's of the air handler wiring diagram where the thermostat wires land inside the house, and a photo of the printed circuit card that shows the thermostat wiring there, same on the outside unit.
You are working with a total mess there, I need to see the totality of it... seeing just parts here and there doesn't help me sort this out for you... even then its a long shot.
They also ran wire to and from the wrong terminals, as well as having the color code incorrect...the 24 volts has to be rewired entirely, 100% from scratch.
This is not slightly screwed up, it is completely screwed up...I have found over my half century in this business that it is virtually always better to start from scratch, even in cases not half as bad as this.
Hello again, thanks for the great pictures.
This is the install manual for your thermostat
see page 4
This is something that will take a few hours to sort out online here, but that a well qualified, and long experienced HVAC tech could wire for you in less than 30 minutes
We can go from there any way you wish. if you want to hire this done, tell me which direction you are from the center of the nearest city...I can probably locate one or two well rated companies for you in that case.
Thats good, I will put up the rating box now, stay in touch for anything else you need on this, rating does not close the question or increase your charges, but it does fund my ongoing ability to follow up on these sorts of questions.
