The valve is in backwash position; the display indicates the

If the remaining volume is superior to 9999 litres, “x1000” appears to
indicate that the numbers shown have to be multiplied by 1000
Ex: 10.5x1000 = 10500 litres of capacity.
In volumetric regeneration mode, these two displays indicate:
- Fig. 1: “consumed” reserve, 100 litres remaining
- Fig. 2: exhausted reserve, immediate or delayed start in regeneration
depending on the adjustment.
In delayed volumetric mode, the icon flashes as soon as the reserve
(if there is) begins to be used.
