Regeneration volumetric immediate
Under normal operation, the display alternates between the time of day,the volume remaining and the tank in service.
(U1 or U2). The volume display is in litres. Progressively with the use, the volume remaining display decreases from
the maximum value down zero or (- - - -). When this occurs, a regeneration is started immediately. A water flow is
indicated by the flow diode that flashes at a varying speed according to the water flow. For example:
Volume remaining 530 litres
Volume remaining 0 litre
* For capacity figures please refer to Apendix A
Immediate volumetric regeneration with a calendar overide
When the set number of days between each regeneration is reached, a regeneration is started immediately. Regeneration
occurs whether or not the volume remaining has reached zero.
Control during a regeneration
During regeneration, the valve will display the number of the regeneration cycle stage to be reached (display flickering)
or reached and remaining time for this cycle (fixed display). Once all of the regeneration cycles are carried out, the
valve returns to the service position. For example:
The regeneration is in stage 2 with twenty-seven minutes remaining.
To step from one cycle stage to the next during regeneration, press the
key. This will have no effect if the valve is
already moving between two cycles.
Operation in programming mode
One can enter the programming mode only if the valve is in service. During the programming mode, the valve still
operates normally and records all information. The valve program is stored in a non volatile memory.
Operation during a power interruption.
During a power outage, all the data is saved to be restored once the power is returned. The programmed data can be
stored for years without loss. The Electronics will be inoperative during power outage and any programmed
regeneration will be delayed. The Electronics restores all information from the moment to which the power stopped. An
incorrect time will indicate that there was a power interuption.
