Table 5: List of Alarms
On page 11.0 you can set the system status in ON, OFF or controlled by a remote
signal EXT (digital input I1).
If ON is selected the pump is always on.
If OFF is selected the pump is always off.
If EXT is selected, reading of the status of digital input I1 is enabled. When input I1
is energised the system goes ON and the pump is started (on the Home Page the
messages "EXT" and "ON" appear alternately at bottom right); when input I1 is not
energised the system goes OFF and the pump goes off (on the Home Page the
messages "EXT" and "OFF" appear alternately at bottom right).
For the connection of the inputs see par. 5.5.1
