ABSTRACT:
An apparatus for interconnecting a four wire control such as a thermostat and a four wire system such as a heating/cooling system with two wires. An encoder encodes signals provided by the thermostat so that four encoded signals may be transmitted over a two wire system. The apparatus includes inductors which are selectively connected to the thermostat thereby providing varying signals which can be delivered over the two wires between the thermostat and the system.
