6.5.9.1
Operation without flow sensor
When the setting without flow sensor is selected, the FK and FD settings are automatically disabled as these parameters are not
necessary. The parameter disabled message is indicated by an icon showing a padlock.
It is possible to choose between 2 different operating modes without flow sensor by means of the parameter FZ (see par. 6.5.12):
Minimum frequency mode: this mode allows you to set the frequency (FZ) below which it is considered that there is zero flow. In this
mode the electropump stops when its rotating frequency falls below FZ for a time of T2 (see par. 6.6.3).
IMPORTANT: An incorrect setting of FZ causes:
1.
If FZ is too high, the electropump could cut out even in the presence of flow and then start again as soon as the pressure
falls below the restarting pressure (see 6.5.5). So there could be repeated episodes of switching on and off, even quite close
together.
