o feedwater setting (Installer menu)
In the event of no feedwater, the corresponding “No water” alarm is displayed. After the alarm has been displayed and the “no
feedwater time” has elapsed, the controller attempts a new fi ll cycle. At each attempt, the “no feedwater time” is multiplied by the
number of times it has already been carried out. The controller therefore performs a series of attempts to refi ll with water, for a
maximum time of fi ve hours after the alarm occurs. The alarm is reset only if the water level eff ectively reaches the intermediate
position (yellow LED).

Description
Ec14
Retry time with no water Set the time to check for no feedwater.
Default: 10 minutes
Possible settings: 0-20 minutes
Step: 1 minute
Remarks: if the value is set to 0, no more attempts will be made to refi ll the water and the alarm will not
be reset

12.5.8 Enable and set high conductivity alarm (Installer menu)
The controller allows conductivity thresholds to be set for the activation of alarms when the limits are exceeded. Excessive
conductivity and consequently high concentration of salts in the feedwater can be signalled. These alarm thresholds are pro-
grammable using the following parameters:

Description
Ec15
High conductivity
Enable the high conductivity alarm and set the alarm delay.
Default:
enabled: YES
alarm delay: 60 seconds
Possible settings:
enabled: YES/NO;
alarm delay: 0-300 seconds
Remarks: once the threshold has been exceeded (if the alarm is enabled), the controller waits for the
“alarm delay” to elapse before displaying the alarm. If during this waiting time the conductivity falls back
below the threshold, the alarm is not activated. This helps avoid false alarms due to variations in the
conductivity reading.

S
et high conductivity alarm thresholds (Installer menu)
Two high conductivity thresholds can be set. If exceeding:
• the fi rst (lower) threshold, a warning is shown without stopping operation;
• the second (higher) threshold, an alarm is activated and the unit shuts down as a precaution.

Description
Ec16
High conductivity
Set the high conductivity thresholds.
Default:
warning: 1250 μS/cm
alarm: 1500 μS/cm
hysteresis: 25 μS/cm
Possible settings:
warning: 0-1500 μS/cm
alarm: 0-1500 μS/cm
hysteresis: 0-100 μS/cm
Remarks: the hysteresis is used to reset the alarm if the conductivity falls below the threshold
minus the “Hysteresis”.
