During the winter time our house is so cold that I don't worry about using one for the heat lamp. Summer time though our bedroom is usually about 75-80 degrees. no problem, just don't use the heat emitter, except, this is the year we finally got an extra AC unit for the bedroom. Makes sleeping glorious, but now I have the issue of, the bedroom is 75-80 when we aren't in there and 66 when we are. I've been unplugging the heat lamp when we aren't in the room, the problem arises when it's 2am and I bolt up out of bed because I remember the lamp is unplugged. So I'm going to hook the heat emitter up to a thermostat, but where would I position the probe for this? Also, do I set the emitter probe to 80?
