Thermostat Wiring For 110v Fan

[rnichols430]

I kinda think I understand the concept required to make it work. But it has been years since I have even sat down to try to figure something like this out..

What I am trying to do is use an inline fan to remove heat from my av/server closet, and put it into the attic. What I would like to do is use a digital thermostat that is low voltage, to control this 110v fan in the attic. I understand I would probably need a 24vac source of power, and then a relay. But has anyone see a guide on how to do this? or have any ideas?

Thanks.

The basic concept is that the thermostat is acting as the relay to trip a 24VAC triggered contactor that can switch 110V. You would have a 24VAC transformer with one leg going to the "R", "RH" or "RC" (depending on the type) on the thermostat and the other leg going to the "C" on the thermostat and to one side of the 24VAC trigger of the contactor. You would then need a wire from the "Cool" terminal on the thermostat to the other side of the 24VAC trigger on the contactor.
