IMPORTANT: This indicator can also come if the upstream water softener is in regenera-
tion mode, but then there is no malfunction, for after regeneration the system turns itself on
again. If the latter does not happen, then there is, in fact, a malfunction and the remote fault
indicator goes on (switch closes).
LED Operation: This green LED is always lit when pure water is being produced.
LED Tank full: The system generates pure water into a closed system. The pure wa-
ter tank (both wall and standing models) also follows this concept. A
pressure switch at the exit of the pure water system indicates that the
tank is full and the green LED lights up.
LED Conductance: The conductance of the pure water being produced says a lot about
the functioning of the pure water system. If the conductance leaves a
certain defined range, the system is no longer working properly. For
this reason, the conductance of the water being produced is monitored
continuously. If the boundary value is exceeded the red LED goes on
and the remote fault indicator switch closes.
LED Lack of salt: When this red LED lights up then there is no longer enough salt in the
water softener's supply container and the remote fault indicator switch
closes. When the container is refilled with salt it takes about 20 min-
utes for the sensor to notice that there is enough salt again.
LED Regeneration: This red LED is lit when the water softener is in regeneration mode,
and when this mode terminates the LED goes off.
LED Rinsing: With every restart, regardless of the reason for which the system
stopped, a magnetic valve ensures that the first freshly produced pure
water does not flow into the tank but is directed to the drain. During
this process this yellow LED is lit.
The system is equipped with a fresh water mechanism. There is a danger that stagnant
water will germinate if, after the tank has filled up (LED "Tank full" is lit), 10 hours elapse
without sufficient consumption of pure water (the system has not entered operating mode).
To counteract this danger, the system then goes into operating mode for a short period of
time and LED "Rinsing" lights up.
