DHW METHOD 4a: Space Heating with DHW Override of Setpoint on MASTER, using an Aquastat, Primary
Secondary, Reverse Return
In DHW METHOD 4a, the MASTER’s
Heat Demand
input enables space heating by energizing the system pump and
maintaining the Heating Setpoint at the MASTER’s System Header Sensor. When the Aquastat located in the DHW tank calls for
heat, the system loop temperature is overridden with the DHW Setpoint. The system pump continues to run, and the DHW pump
is enabled 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.
