Need a 120volt line cooling thermostat

I need a 120volt thermostat that can be used for cooling instead of heating. What I have is an air conditioner, and I want to be able to turn the outlet it is plugged into off and on with a thermostat.

Thanks

Lightbulb Make your own "circuit"

Get a 24v thermostat, an electrical outlet and a transformer.
Also you will need a 24v relay/contactor.
Wire it up like a central A/C condenser circuit.
You will get MUCH better tempature regulation this way and you can use a programmable thermostat if you like.

I am currently using 2 of these circuits in my house right now

OR you could use a line voltage thermostat designed for an evaporative cooler if tempature accuracy isn't an issue

Lightbulb What do you have on hand ??

Do you happen to have any relays or transformers lying around in the garage ??

I always like to make them with what I have on hand ..

Anyway basically use 120v line coming in and step it down with the transformer.

Hook the hot leg of the 120v line to one terminal on the contact of the relay, hook the other contact to the "load"

Hook the line nuetrals all together.

Hook on side of the 24v transformer to the coil of the relay, hook the other side to the relay through the thermostat

I know in explaination it sounds complex but it's really quite simple.
