However, if you must know about electric blankets: everyone is right. There are temperature sensing devices (thermostats?) inthe blanket itself the control box. The one in the control box is the one that controls the amount of current to the blanket, hence, its warmth. As the room gets colder, this control heats up the blanket more. There is an adjustment for how hot do you want to be anyhow, sometimes two adjustments: one for each half of the bed. The temperature sensors the blanket itself are there to keep you from burning up if something goes wrong and the blanket overheats (say you have covered part of it with a heavy blanket or stuck the heating wire under the mattress). Think of these sensors as fuses. Dick Grantges hound!rfg
