Hi everyone, I am having troubles wiring a new thermostat into my home. My home is only 2 years old, and the thermostat that came with it stopped working. The problem is when my fiancé unhooked the old thermostat he didn't label any of the wiring and now we have no clue where anything goes. Now it's getting extremely hot outside and we have 2 kids to worry about keeping cool. PLease help me out here.

The wires are red, green, blue, white, and yellow.

The thermostat has these G, RC, RH, Y/O, W/B, Y1

Thanks in advance to all that help! :):)

Green to g
Red to rc jumper to rh
White to w
Yellow to y
