Correct
Q: What characterises the FLOWLIMIT technology?
A: The FLOWLIMIT technology makes it possible to set a max flow, which means that the design flow is never exceeded regardless of pipe diameter and pressure loss.
Correct
Q: What causes system imbalance?
A: System imbalance is often caused by pressure loss in longer pipe sections.
Correct
Q: How can the MAGNA3 pump ensure optimum condensation?
A: The FLOWLIMIT technology built into the MAGNA3 makes it possible to set a max flow and eliminate the potential overflow area to ensure that the return temperature stays below 57°C.
Correct
Q: What are the benefits of using the handheld controller Grundfos GO with the MAGNA3 in terms of balancing?
A: The FLOWLIMIT function can be accessed remotely via Grundfos GO and the flow limit can be set in no time to make commissioning easier than ever.
Correct
Q: What are the consequences of an unbalanced system?
A: An unbalanced system will add to the energy consumption and also affect the indoor climate of a building.
Correct
Q: What makes balancing heating systems in commercial buildings a challenging task?
A: The distance from the pump to the final consumer means that the pressure can vary widely depending on the flow.
