automatically calculate the system water treatment capacity and display on the LCD screen.
3. Water hardness can be adjusted: It can adjust the hardness of outlet water by adjusting the
bypass.
4. Automatic memory function: The parameters set by users, such as regeneration time, backwash
time, brine & slow rinse time, brine refill time, fast rinse time and so on, can be saved permanently no
matter how long the power is off. If power off is more than 3 days, it will always display this interface to
remind to reset the time of day (See below picture)
5. Language: Chinese or English can be chosen. After power connected within 6 seconds, press and
hold both and for 5 seconds under the service status, the system will turn into language
selection interface.
6. Buttons lock function: No operations to buttons within 1 minute, buttons are locked. Press and hold
the “ ”and“ ” buttons for 5 seconds to unlock. This function can avoid incorrect operation.
7. Regeneration mode is meter delayed type: Regenerate on the day although the available volume
of treated water drops to zero (0). Regeneration starts at the regeneration time. It can avoid the shortage
of water for regeneration.
8. Working automatically:
Softening: Under a certain pressure and flow rate, the raw water flow through the product, at the
same time, the calcium ion and magnesium ion of raw water are replaced by the sodium ion of resin,
reducing the content of calcium ion and magnesium ion and realizing the purpose of softening water.
Backwash: After the resin is saturated and lose softening efficacy, the program start backwashing
before regeneration. On one hand, it can wipe off the broken resin and the impurity on surface layer of
resin. On the other hand, the reversed flow direction can loosen the tight resin and make it benefit for the
touch between resin particle and regeneration liquid.
Brine & slow rinse: A certain concentration brine flow through the resin. Meanwhile, the calcium ion
and magnesium on the resin surface layer are replaced by the sodium ion, making the invalid resin
regeneration and recovering its softening capacity.
Brine refill: The brine tank is refilled with water to dissolve the salt so as to provide the saturated brine
for next regeneration.
Fast rinse: Discharge the residual brine and compact the resin particle so as to reach the best
