11.6.3.2 Procedure

If flow – tolerance monitoring is activated (when tolerance value is unequal 0 ), the
tolerance monitoring starts as soon as a flow value is known.
This value is only calculated when temperature setpoint is reached.
Until then "- - -" is shown at the display.
As soon as actual flow rate is outside of tolerance, the error message "H78" is
shown at the display and LED begins to flash.
If the flow rate value is within of tolerance band again, this error message resets
automatically.
If at these flow rate menus no button was pressed for more than 25 seconds, an
automatically switching back to display "temperature ACT" takes place.
From these menus, if no key was pressed for longer than 25 seconds, display
jumps back to Mode 1 (ACT-temperature).
