This short book explains hot water heating (hydronic) controls and circuits from the perspective of power suppy, switch, and load. The book starts with a simple control circuit and builds to multiple zone circuits. It explains that adding a control panel simplifies a job rather than making it more complex. The book then looks at various panels, building from an aquastat relay to multiple-zone and multiple-purpose panels.
