When the Aquastat located in the DHW tank calls for heat, thesystem loop temperature is overridden with the DHW Setpoint. The system pump continues to run, and the DHW pump isenabled to supply heat to the tanks until the Aquastat is satisfied.Boilers are staged to meet the active setpoint based on their runtime, and each boiler will enable its local pump when it is running.The Master modulates the boilers in order to maintain the active setpoint.
