Question about Heating & Cooling
Y or yellow and G or green are connected in the "auto" setting, as G is fan and Y is cool, the Y and G wires are somehow, energizing the Y wire that goes to the AC unit to run cool, take thermostat off exposing the thermostats sub base Y and G will be there along with R, red, 24volt ("hot leg" of 24 v power) W white= heat, and C common, 24 volt ("neutral leg" or "common" leg of 24 power) common is where all the various 24 volt circuits (cool, heat, fan,) terminate or return to complete the circuit, just as a AA battery nas a positive and negative side of power, so does the furnace and all electrical circuits, its common as all circuits terminate there , its the opposite side of power fro whish all circuits begin, red is the :hot leg" and enters on RED red to WHITE=HEAT
RED to YELLOW=COOL
RED to GREEN= FAN
auto =Y & G connected
on= R & G connected
if you jump red to green, which is fan on, no connection should exist to yellow in on ! only auto!
