I need a wiring diagram for a starndard residential split a/c system. Just the outdoor section is fine.
Hi, if this is just a split standard heating and cooling unit, and not a split heat pump, all you need to do is pull stat wire from the indoor unit control board to control the condenser with 5 conductors, but you will only use 2 wires for the control of the condenser. Normally, the red and white tie to the 2 control wires of the contactor. Back at the control board, red to red and white to the Y or yellow terminal. You will also need to set your disconnect box for your high voltage near the condenser, where you will be coming from your breaker to supply high voltage to run the motors and compressor. Very easy to do. If it is a heat-pump, you will need to pull at least 8 conductor thermostat wire to wire this up. I would also need to know what terminals and kind of thermostat you have, and if you are using heat strips for second stage of heat. When you say standard unit, you will only need 2 control wires from the indoor to the outdoor unit, along with the high voltage. Please keep me posted and let me know if you need more help on this. A wiring schematic wouldn't be needed if its just a standard condenser.
