Whats the deal with the stage 2 heating with this unit? Mine has never kicked into 2nd stage heating even when the temperature is close to 0. What coukd be the issue?

Verify W1 & W2 low voltage terminals are not tied together and that the thermostat has the ability to run more than 1 stage of heat.
