THIS NORMALLY LOW VOLTAGE AND BY PASSES THE
THERMOSTAT ON YOUR LARGEST HEATING ZONE.
THE SETON BOILER REQUIRES SOME MEANS OF KEEPING THE PUMP FROM CIRCULATING WA-
TER WHEN THERE IS NO HEAT OR FIRE IN THE BOILER. THIS KEEPS THE BOILER WARM AND
HELPS TO PREVENT CONDENSATION BUILD IN THE BOILER AND ALSO KEEPS HEAT FROM THE
BACKUP BOILER FROM DISSIPATING ITS HEAT THROUGH THE WOOD BOILER.
THIS AQUASTAT SHOULD BE LOCATED CLOSE THE NATURAL CONVECTION INLET FROM THE
WOOD BOILER ON THE MANIFOLD.
