i have just installed a new heating system in my home. the tstat wiring from the furnace to the thermostat was clear but i can't figure out how the control wire works from the condensing unit. the condensing unit has two purple wires.
hopefully you installed it correctly but seeing that you dont even know how the remedial wiring should be you should stop and run out the door now before you do any more damage then from a payphone far away call you nearest hvac person. Also, there is a reason why on the front of the installation manual it say that a professional hvac contractor should install it and not a home depot or lowes question asker!!!! THANKS FOR THE LAUGHS
