thermostat for A/C

I wanted to hook my A/C into my JC thermostat and can't figure out how to use it for an air conditioner. Any hints?

Isn't there a cooling mode that you set it to?

Vaughn! Where you at?

Open it up and at the top you will see two jumpers. You need to move the top jumper, Jump 1, so one of the pins are not covered. That will put it into cooling mode.
