Question 3 of 6 Intermediate

3 In which systems can the calculated proportional differential pressure mode be used?
In systems where measurement of the differential pressure in the system is not an option and where the valve authority is more than 50%
In systems where measurement of the differential pressure in the system is not an option and where the valve authority is below 50%
In systems where the differential pressure is measured in the system and where the valve authority is below 50%

Question 4 of 6 Intermediate

4 In which types of systems is the constant pressure mode used?
Systems where the valve authority is higher that 50% of the total pressure loss
Systems where the valve authority is lower than 50% of the total pressure loss
None, this control mode is outdated

Question 5 of 6 Intermediate

5 In the case story, which system is the most expensive?
A system with constant flow and a single constant speed pump
A variable flow system with a single constant speed pump
A one pump system with variable flow and variable pump speed where the pump is put into calculated proportional differential pressure mode

Question 6 of 6 Intermediate

6 In which systems can the measured proportional differential pressure used?
Systems where the differential pressure is measured over the pump and the valve authority is below 50%
Systems where the differential pressure is measured in the system and the valve authority is below 50%
Systems where the differential pressure is measured in the system and where the valve authority is higher than 50%.
