Injection circuit with a replaceable pump model for the distribution of hot or cold water. All sensor and actor values are connected to the hydraulic bus.
When the valve is fully opened, the consumer module is plugged into the primary hydronic circuit (port_a1, port_b2) whereas when the valve is fully closed, the consumer is isolated from the primary hydronic circuit. The primary needs a supply pump or a pressure difference.
This model uses a pipe model to include the heat loss and insulation effects
