Question about Heating & Cooling
Hopefully there are markings on the old t-stat as to what terminal is what.
on the honeywell 8000 use the heat pump labeling and then the standard wiring would be
There should not be a bare wire, it probably just has the insulation stripped back way too far.
You should probably open the furnace and compare the terminal label in the furnace to the wire color. normally yellow and blue pass through the furnace and are wire nutted to wires going to the outdoor unit. In the furnace the white wire will connect to the w or w1 terminal. also, you will need to set the Honeywell stat to have the following parameters.
other parameters that I did not specify, you may read the manual and make your own decision but I recommend factory settings for the other parameters

There is a sensor that shuts the compressor down when the freon (refrigerant) is low. The tech probably "shorted" out this sensor. If the unit went on when he did this, the charge is low.

Every thing the same except take your blue wire and replace the yellow for it. So when you hook it to t-stat goes like this
Red to R
White to W
Green to G
Blue to Y

Hook up o to o/b, then in the installation programming set the change over valve to energize in cool. Then hook up w to aux. Good luck.

Your old stat is wired for a traditional thermostat and not a communication stat like the new infinity you have. There is a module plug on the furnace board that will need to be connected to the new thermostat for it to work. The wires that are wired now are from a terminal strip inside the furnace. Please contact your local Carrier dealer. They may be able to get that harness for you
