What is a rheostat? A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. The construction is very similar to the construction of a potentiometers. It uses only two connections, even when 3 terminals (as in a potentiometer) are present.
High voltage systems. High voltage systems are usually electric baseboard heating systems or other radiant systems powered by electricity. High voltage thermostats are built into the wall and have 2-4 thick wires that come out of the back of the thermostat. These wires connect with wire nuts to corresponding wires coming out of the wall. Only high voltage thermostats have thick, stranded wires coming out of the thermostat itself.
