13 HYDRAULIC CIRCUIT AVAILABLE HEAD PRESSURE
Below the characteristic curves corresponding to Head pressure -Water flow without head losses of the hydronic kit. The optimal
operating point is shown on each curve under the specified conditions at the apex (3) p. 17.
The circuit’s plant must be designed so as to ensure the nominal water flow rate corresponding to the operating points indicated
below.
Here also the range of the available head pressures that the unit can provide during the circulator modulation periode.
