13.4.8.3. Constant output pressure mode
The controller manages the pump's speed to maintain an even water pressure at the output of the unit, regardless of the
number of operating terminals.
The hydraulic facility must include a system that retains the required minimum water pressure when the

terminals' two-way valves are shut.
