Thermostat wiring


I am installing a Honeywell RTH6300B thermostat. Do I connect my existing w2 & o wires to the same terminal? What do I do with my E wire? Please and thank you.

What does the installation manual that came with the thermostat state? If you do not have the manual, it is available at honeywell's website.
