Thermostat?

Hey guys what's up. I just posted in the beginners brewing that I brewed my first batch! Well so far all is going well, good steady fermentation going on.

I have a question though. Right now I have my air conditioner on 65 degrees, and it's only cooling my beer to 77. It hasn't passed 80 yet, but I still feel a bit worried. I can't run this air conditioner for 6 weeks at 65 degrees, or I'd be giving myself a hefty electric bill. I live in Louisiana, so it's getting hot right now.

Well the good thing is I bought a new refrigerator, and I have my old one on the front porch. I bleached cleaned the old one, put an indoor/outdoor thermometer in there, and even on the warmest temperature setting, it's at 46 degrees right now.

I guess my last option now is investing in a thermostat to keep these temperatures under control. What is a good thermostat to invest in? I remember seeing some pictures of a thermostat with a red digital display on the temperature. What is the links for some commonly used thermostats for brewing? I saw the ones on Midwest Supplies website too. Thanks!

Look for a Ranco digital on Ebay for a lot less then Midwest!!

I buy a lot of stuff from micro matic.
They have two thrmostats on this page

Ranco and Johnson controllers are very common -

Keep in mind, if you use these to maintain your fridge temp up near 65, the freezer won't be cold enough to store frozen food.

Keep an eye on eBay. I got a Johnson A19 controller for under $15 and a Ranco digital controller (much nicer) for under $40. These are exactly what you need.
