Yes, your lightbulb (or whatever your heatsource will be) is hooked up through the thermostat, so that it can turn them on and off. Lots of people use the water heater thermostats for incubators, but I'm the last person to advise you on hooking it up.I tried one of those first and I guess I must have broken it or something because I never could make it work.
Great, thanks. I will ask someone on here how they hooked theirs up.
I have read that the thermostat sensor need to be fairly close to the heat source or the temperature will vary too much.
Good Luck!
Thanks!
