ABSTRACT:
A programmer (controller) permits individual control of a plurality of devices associated with the same installation, such as an installation for heating residential rooms, offices, or the like. The programmer includes a clock, at least one counter which periodically receives pulses from the clock, and a programming matrix composed of a double-sided printed circuit. On one side of this circuit, a first plurality of parallel conducting strips are provided, each of which is connected to one output of the counter. On the other side of the circuit, a second plurality of parallel conducting strips are provided, each of which crosses those of the first plurality and is connected to one control circuit of a device. At each intersection of a strip of the first series and a strip of the second series, an aperture is provided which can receive a removable pin which provides an electrical connection between the two sides of the printed circuit.
