1: With a single dedicated pump for each terminal unit, which control mode is used?
Constant temperature
2: Why is there in most cases no bypass flow with a distributed pumping system?
Because primary pumps try to match primary flow and secondary flow
2: Why is there in most cases no bypass flow with a distributed pumping system?
The bypass valve is always closed
