This stat should work if the furnace control board has the feature where on 1st will time out and then go into 2nd stage.
Read the install manule to see

The thermostat is not correct for the furnace. The could still use the system on only one (low) fire setting by connecting W1 to W on the thermostat. You actually need a 2 Heat thermostat for this furnace.
