1: What can happen if systems and zones are poorly balanced?
This may result in decreased Delta T and lower end-user comfort
2: What is Grundfos FLOWLIMIT?
An electronic flow commissioning and limiting functionality built into the pump
2: What is Grundfos FLOWLIMIT?
An external controller that works with the pump
