I have thermostat wires from the wall... blue, red, yellow, green.

Central air and forced air gas furnace.

Labeled connections on Thermostat are Rh and Rc (with red jumper), and W, Y, G.

Which wall wire goes to what therm label connect?

Help :)

Red to rh or rc with jumper
Green to g
Yellow to y
Blue ( which normally is white ) to w post
