Installation
AVAILABLE PRESSURE
The indicated curves account for the pressure drop due to the module.
Therefore, you only need to calculate and compare the pressure drops in the entire
circuit, by using the reference curve (see graphs), to check whether installation has
been performed correctly.
Warning: if thermostatic valves are installed on all terminal or zone valves, a by-
pass should be inserted to ensure minimum operating flow rate.
