"Delete Alarms Log?"
Pressing OK (left button) deletes the alarms memorised
in the log.
On page 12.0 you can set the system status in ON, OFF
or controlled by a remote signal EXT (digital input IN1).
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
IN1 is enabled. When input IN1 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 IN1 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. 6.2.1
