DHW Method 5a: Local DHW Tank Heating using a 10k Tank Sensor.
Example: DHW Heating to a Local Boiler’s Tank,– Method 5a
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 then disables its local pump and enables its DHW pump 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.
