Circulator Operation

1.Unzoned Systems, or Circulator-Zoned Systems — The thermostat cycles the circulator motor (through a relay) to meet the demand for heating.

2.System Zoned with Water Valves – Auxiliary contacts of water valves cycle circulator motor (through a relay) to meet the demand for heating. (The circulator runs as long as any zone is calling for heat.)
