sounds like you dont have the right stat if no w2 or aux terminal on new one. Do you have a heatpump with back up heat (electric strip or gas)

Your Honeywell thermostat uses W/OB as your B on the old stat, and W2 as the W on your old stat.

Sounds like you have a Rheem/Rudd/Weatherking heat pump. If so, you also have to tell the stat to energize W/OB in heat mode.
