Is it a 2 stage furnace?

I'll bet that you only have the first stage hooked up. You'll need a 2 stage thermostat and both whie wires hooked up.

To find out if your furnace is a two stage, open the panel to access the control wiring. W1 is the first state, W2 is the second stage. Note the color of the wires going to each terminal.
