DHW Method 3: DHW Heating Only, Using a Header Sensor Input
Figure 33 Example: DHW Only Using Header Sensor, Primary/Secondary – Method 3
DHW METHOD 3: DHW Heating ONLY using a Header sensor input, Multiple Boilers, Reverse Return.
In this method a Heating Setpoint is maintained at the MASTER’s System Header Sensor located in the DHW tank. The
MASTER’s Heat Demand input enables space heating and maintains the Heating Setpoint at the System Header Sensor. Boilers
are staged to meet the setpoint in the DHW tank based on their runtime, and each boiler will enable its local pump when it is
running. The MASTER modulates the boilers to maintain the Heating Setpoint at the header sensor located in the DHW tank.
