4 - VALVE OPERATION

Timeclock regeneration
The number of days between each regeneration cycle is preset. Once reached, regeneration is triggered at the
programmed time.
Metered regeneration
The valve calculates the amount of water it can soften between 2 regenerations based on the exchange capacity
(m3°tH) and inlet water hardness that are preset.
Immediate or meter delayed regeneration valves
As softened water is used, the remaining volume display will decrease until reaching its reserve capacity (meter
delayed regeneration) or until zero (immediate metered regeneration). When this happens, regeneration is
automatically triggered either straight away or at a preset time.
Service
Service display
In operation, the time of the day and the volume remaining will alternatively be displayed (except for the time clock
version: only the time of day will be viewed).
Time of day Remaining Volume: 765 1

If the remaining volume is higher than 9999 litres, the letter « t » will appear
to indicate that the indicated number must be multiplied by 1000.
I.E. t 15 = 15 *1000 = 15 000 litres capacity.
In delayed metered regeneration, this display indicates that the remaining
capacity is exhausted. The service position L.E.D will flash and a
regeneration cycle will start at the programmed time.
Time of day setting
Set the time of day minute by minute by pressing the or button. Press and hold the button to set quickly
the time of day.
Regeneration
Regeneration displays
During the regeneration cycle, the valve will show the current cycle number the valve is advancing to (flashing
display) or has reached as well as the time remaining in that cycle (fixed display). Once all the regeneration cycle
steps have been completed the valve will return to the service position.
For example:
The valve is advancing to its 2nd cycle.
The number 2 and the L.E.D. are flashing.
The valve is in its 2nd cycle;
there are 65 minutes left.
