What color wire is connected to the "Y" terminal on the thermostat.
If the unit you are connecting is a heat pump A/C unit the orange wire is for the heating mode. Normally the "Y" terminal on the thermostat. "R" terminal on the thermostat is the power to the thermostat, "W" terminal is for heating, "Y" is for cooling, and "G" terminal is for fan operation. At the condensing unit for cooling the brown and yellow wires would normally be for the cooling.

You have a safety limit switch that is either bad or needs to be manually reset. Some have little buttons between the two wires going to the switch that you can push to reset. If not they are automatic switchs then one is bad. You have to do an ohms test to see if each switch is bad or good.

SOURCE: Need help with wiring thermostat
first do you have a heat pump unit or standard a/c? standard a/c connections at the thermostat go like this red wire to rh-rc which is the 24v power and you don't have to remove the jumper.white goes to w which is the heating wire yellow goes to y which is the cooling wire green goes to g which is the fan wire and blue goes to c which is the common wire. so if your stat has rc- rh ywgc you should be set if the wires on the furnace correspond with the same alpha designation.orange may be used if u have a heat pump unit otherwise it may just be a spare you cap off and leave behind the subplate.

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
