DHW METHOD 5a: Local DHW Tank Heating Override using a 10K Type II Tank Sensor.
In DHW METHOD 5a: Local DHW Tank Heating Override, 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 using the available
MEMBERs. A MEMBER boiler will enable its local pump when called to service a heating call by the MASTER. Each
MEMBER has its OR OVR input jumped to enable local DHW heating using its DHW Sensor. When a DHW tank sensor calls for
heat, the local boiler goes offline from the MASTER. The boiler can disable its local pump (Programmable), and enables its
DHW pump/valve to service the local tank until the tank sensor has been satisfied. Once the call for DHW heat has been satisfied,
the boiler is placed back online for the MASTER to service the main heating loop.
