Help me control my furnace's blower

How can I reconfigure my Goodman GmH950703Bx furnace so that it doesn't blow all the time?

I have some vents in my slightly-poorly-insulated house that run alongside outer walls, which causes air in them to become cooler than it otherwise would be. That, combined with my new furnace's apparent default setting to always have the blower on, has cool air coming out of the second-story vents when the thermostat detects that the main floor is adequately warm.
My old furnace only ran the blower when the heater was on; at other times it was totally idle. That's the state of affairs I'd prefer to have. The thing is, the wiring for the thermostat has only two wires, which apparently only gives us control of the main on/off control (or something like that -- I'm no expert!).
How should I proceed in resolving this?
