that the figure is between 0.6 and1.5 bar when the system is cold.
If the pressure is just under the minimum value the display will
request a filling procedure - see note below.

THE FILLING LOOP (POSITIONED UNDERNEATH THE

WHEN THE PRESSURE GAUGE INDICATES A PRESSURE
OF 1 BAR, CLOSE THE FILLING VALVE AND PRESS THE
MODE BUTTON. THE DISPLAY RETURNS TO NORMAL
VIEW.
Re-establish the correct pressure by filling loop.
If the pressure drops very frequently, there may be a water leak
at some point in the system. If this is the case a plumber should
be contacted.
