Regulating probe sensitivity
Regulation is obtained by setting the sensitivity value. For a new regulation, proceed as follows:
Check that the water level covers the probes.
Ensure that L.O.W. AL.DELAY is set at zero.
Vary the sensitivity level slightly until the red "LOW WATER" led is lit and the respective alarm message
appears.
Slightly increase the numerical value of sensitivity until the red "LOW WATER" led goes out.

probes/float/minimum pressure
switch connected to the dedicated
terminals HIGH (22), LOW(23) and

Regulating probe sensitivity
according to water conductivity.
Setting the analog signal used as
system feedback.
If AI1 or AI2 is selected, in case of a
sensor fault feedback is
automatically provided by the
alternative sensor.
