I have a LUX 1500 series thermostat, my existing wiring is Red, White, Green and a light blue ( total 4 wires ).
Also my home is gas heat forced hot air / with a central air cooling system.
Current problem, I have heat, but no ac. I don't believe I wired correctly, and don't know if I need a jumper wire...
Thank you in advance, Sebastian

Thank you,
One last question, I don't have any "jumper wire" for my thermostat, what type of wire do I need to buy ? I have a Home Depot or Lowe's nearby ?

Just cut off a extra piece of wire from your stat. all you need is a small piece. If you can not find a extra piece at the stat look in the bottom door of the furnace. Odds are there will be plenty extra there.
