First write a simple document that describes your goal; what do you want the control system to do. In a large scale computer control system that would be called the "functional specification".
next you will need sensors and computer controlled relays to control your AC from your computer.
Several manufacturers provide RS-232 Digital relays, and although there are, in fact many manufacturers, I have used the relays and serial data acquisition modules from B&B electronics and have found them to be of good quality and relatively inexpensive. Other manufacturers provide industrial rated devices that are much more expensive.
After selecting the digital I/O control equipment that you will be using, then you can create the computer program that communicates between the different devices and provides the functionality that you want.
After selecting the hardware, it's a good idea to resurrect the functional specification and start to fill in the specifics, for example, if you wrote in the functional specification that you want to turn on the fan motor, that's when you would determine the sequence that you would send to the data acquisition module to turn on the fan. This step saves a lot of trouble later so that you don't need to re-write segments of code because of a surprise that you encountered when reading about how to turn on a relay. In a commercial system, that document would be called a "detailed system design".
Once you've gone that far, just connect the equipment and write the code.
Have fun.

Function of system bus?
A system bus is a single computer bus which historically was used to connect all the major parts of the computer. It combined the jobs of a data bus, address bus, and a control bus. Over the last 30 years, computers have tended to use separate specialized buses instead of a system bus.

What is the function of the air handler transformer in an HVAC system?
The air handler transformer in an HVAC system is responsible for converting the incoming voltage to a lower voltage that is needed to power the control circuitry of the system. This allows the system to operate efficiently and safely.
How can I install a C wire in my HVAC system?
To install a C wire in your HVAC system, you will need to connect the C wire from your thermostat to the C terminal on your HVAC system's control board. This will provide a continuous power supply to your thermostat. It is important to turn off the power to your HVAC system before attempting to install the C wire to avoid any electrical hazards. If you are unsure about how to do this, it is recommended to consult a professional HVAC technician for assistance.
What is the function of a fan relay in an HVAC system and how does it contribute to the overall operation of the system?
A fan relay in an HVAC system controls the operation of the fan. It helps regulate the flow of air throughout the system by turning the fan on and off as needed. This contributes to the overall efficiency and effectiveness of the HVAC system by ensuring proper air circulation and temperature control.
