Proportional head
The circulation unit works on the basis of the heat request made
by the system. The working point of the circulation unit and the
selected proportional head curve move on the basis of the heat
request
PP1
PP1 LOW proportional head curve
PP2 AVERAGE proportional head curve
PP3 HIGH proportional head curve
Constant head
The circulation unit works at constant head, irrespective of the
heat request. The working point of the circulation unit will move
along the selected curve on the basis of the heat request.

CP1 LOW constant head curve
CP2 AVERAGE constant head curve
CP3 HIGH constant head curve
Constant curve
The circulation unit works at constant speed, irrespective of the
heat request from the system. The working point of the circula-
tion unit will move along the selected curve on the basis of the
heat request.
