Pump configuration
13.4.8.2. Constant speed mode vs capacity
The speed of the pump depends on the capacity of the unit. This speed range is determined during commissioning to adjust
the power of the pump to the load drops of the installation.
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.
CAUTION
The hydraulic facility must include a system that retains the required minimum water pressure when the
terminals’ two-way valves are shut.
Installation of one or more three-way valves on the facility to maintain the minimum required pressure.
