ABSTRACT:
An analog computing circuit which controls a boiler or other heating system in a building, has a timer actuated setback which reduces the temperature of the building at night in such a way that as the ambient temperature approaches the lowest temperature in the temperature range for which the heating system is designed, the magnitude of the temperature drop in the building approaches zero. The analog computing circuit includes a timer actuated boost which is timed to start at a fixed time each morning. The boost causes the heating system to supply heat to the building, after the temperature in the building has been reduced the previous night, at a rate sufficient to raise the temperature of the building to its design level by a predetermined time in the morning.
