A hydronic zone system is an optional upgrade accomplished by adding accessories to a standard boiler heating system. A zone controlled system allows the users to operate and regulate the heat in the home on a room-by-room or area-by-area basis. A zone control system consists of:
• control panel
• one or more circulating pumps
• zone valves (optional on some setups)
• a thermostat for each zone.
