This is why a mixing valve (V2) is introduced to blend Key water within the central plant with return water through the dwelling heating system, therefore allowing for the HIU to fulfill differing needs dictated by DHW and Place heating. In addition, a three port Command valve is needed to divert stream between the DHW plate heat exchanger and dwelling heating circuit; this valve is controlled on the incredibly hot h2o precedence basis. An example of the method is proven in Figure 3.
