Two stage furnace will also have W2. Jumpering R and W2 should engage second stage.

However, you need to confirm the furnace settings, because it's possible the furnace could be configured via dip switches to either: 1) always run in stage 2, or 2) engage stage 2 based on run time (for use with a single-stage thermostat)
