· TIME-OUT
Once the level probe is uncovered, the micro-controller activates an internal timer for the duration of this
stage. If the filling lasts (continuously) for more than 350 seconds, the system blocks the operation of the
device and an alarm is signalled by the red indicator light ON steady. To reset the alarm condition, first
eliminate the fault that caused it to trip (broken or disconnected level probes, water system problems, drain
tap open ...) and then switch the system OFF/ON .

· Total hardness between 0.5 and 5 French degrees to reduce the formation of scale
· Pressure between 50 and 250 kPa (0.5-2.5 bar)
· pH above 7
· Electrical conductivity between 50 and 2000 μS/cm (20 °C)
· Chloride ion concentration (Cl-) not too high (acceptable reference value: 10ppm) to avoid attacking
