Available static pressure [kPa]
The graph provides the available static pressure granted by the internal circulator (P_i) a the maximum speed. The internal circulator speed is managed by the hydronic
board in order to insure the correct water temperature difference as in the table below:

NOTE
For the correct operation of the system, a hydraulic bypass must be provided on the system capable of ensuring sufficient water circulation to avoid the
blocking of the heat pump due to lack of water flow alarm.
This is, for example, essential if the system includes zone valves or thermostatic valves which, if they go into partial or complete closure, would result in
a reduction / lack of water flow with consequent water flow switch alarm and therefore the blocking the heat pump.
