pic related is all the thermostat does
If it calls for heat, it makes a jumper between the R and the W terminals
If it calls for cool, it makes jumpers between RC and Y and RC and G.
The yellow wire is for the contactor and the green is for the blower in the furnace.

I'm glad we got your heat going anyway.
