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 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).

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.

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:

Time of day

The valve is advancing to its 2nd cycle.

The number 2 and the L.E.D. are flashing.

Remaining Volume: 765 1

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.
