Getting Fed Up with rack

a rheostat kind of controls temp, it controls the energy output to a heat device. If the parameters of the enclosure changes, the rheostat doesn't. Say the heat stops working in the winter, the rheostat fails to recognize the drop in temperature in the viv as a result of the drop in the surrounding area. Vice versa if the a/c goes out on a hot day during the summer. Its also possible something (a dog perhaps) bumped the knob. Another member lost a clutch because their cat decided to turn up the temp on the incubator by brushing against the knob. The exact same concept applies to the majority of car climate controls. Its another form of rheostat.
