Might not help.. You see there has to be a source of power to the RELAY on the A/C that turns it on.. I would like to think that when you are in COOL the A/C provides the 12 volts to the t-stat but.... I do not know that for a fact.
I have only worked on 24 volt AC t-stat systems and typically it uses just one source. No matter the mode.
