I think there is a much easier way to present this: The red line carries 24vac; the job of the thermostat is to connect the red wire on R/Rc to either the "G" for manual fan/no compressor selection, or to " Y" for automatic operation of the fan and the compressor per the temperature setting. That is it! The common wire is not even needed and might not even be present for thermostats that are fully battery operated. Often, the common is already constantly connected to the fan relay ELSEWHERE and to the AC Compressor+Fan ELSEWHERE. You don't need a common wire at the thermostat unless your thermostat isn't battery operated and itself needs both legs of the 24 volts to function. The only tricky part is that the AC installer may not have used a cable having a yellow individual lead color, so behind your thermostat you might find only red, blue, green. Usually, red=red, green=green, and blue takes the place of the missing yellow color for Y. This is why thermostat manufacturers tell you to note how a previous thermostat was wired/which wire color went to each of the standard LETTERS before you remove it to replace it.

Correct. The thermostat common is there ONLY to power the thermostat itself, rather than using batteries to do so.

But what powers the thermostat controller program itself ? Is it the batteries, or does it draw 24 volts ac from the mains transformer ? ie are the batteries only to hold the settings during a mains power outage ?
