AVAILABLE PRESSURE
Pressure available for distribution on the installation.
Available pressure
The curves indicated above show the available pressure of internal units.
In order to have a correct sizing of the system, the pressure drop curve of the entire circuit (in function of the nominal ow rate)
must stay below the available pressure curve everywhere. Pressure drop values depend on the specic installation.
You can install a supplementary circulation pump if the module’s own unit is not powerful enough. For the electrical hookup, refer
to «Electrical circuit».
Warning: in case of installation of thermostatic valves on all terminals or zone valves, install a bypass to ensure the minimum
operating ow rate.
