Glad to hear you're getting a Thermostat. They take most of the worry out of keeping the temp correct. Once you get the t-stat, it just takes a little tweaking to get the temp to the correct setting and then you just check it every once in a while to make sure it with your temp gun still in an acceptable range. I'm sure you'll love it, I know I do.
