Abstract
A programmable device for controlling the amount of heat supplied to a building by opening and closing a circuit to a heat source such as an oil or gas burner or a steam valve during predetermined times and in response to the temperature of the outside air. The predetermined times can occur during a multiday cycle, such as a week. As the outside air temperature rises and falls, the circuit will be closed later or sooner, respectively. Additionally, the device can be set so that when the outside air temperature falls below a predetermined level the circuit is closed to add heat to the building notwithstanding where in the programmed cycle the device is. Conversely, the device can be set so that when the outside air temperature reaches a predetermined maximum, the circuit is opened to halt the addition of heat to the building notwithstanding wherein the programmed cycle the device is.
