The volume calculated by
Aqua Timer Plus
can go from 0 to 999,999 litres. This value is optimised in order to be able
to be visualised by the display of the controller which can show only four digits.
A decimal point will appear on the display to separate the Timer metres from the litres, that is the thousands of litres
from the hundreds.
The value of the volume will be visualised from the left to the right, so that a volume value of 15,500 litres will be
visualised as
15.50
, a value of 350,000 litres will appear as
350.0
. During the service, the normal consumption of water
will cause the volume visualised to decrease; when the most significant digit becomes zero,
Aqua Timer Plus
will
optimise the visualisation moving the reference point towards the left, which allows new, less significant digits to be
seen. Thus, the moment the volume passes from 10,000 to 9,999 litres, the visualisation will pass from
10.00
to
9.999,
if
the volume passes from 100,000 to 99,900 litres, the visualisation passes from
100.0
to
99.90
.
If using a pre-programmed prescaler, the volume calculated is optimised by returning to zero the digits which are not
decreased and by rounding it off.
Example
:
If the volume calculated is 15,435 litres and the prescaler is programmed with the type 1/10, the volume will be
decreased by 10 litres each impulse, so that the final 5 would never be returned to zero. The volume will therefore be
optimised, returning to zero the last digit so obtaining the value 15,430; similarly, if the litre counter divider chosen is
the type 4/1000, the volume will be decreased by 1000 litres every 4 impulses, and the 435 litres will never be returned
to zero. The volume will be optimised to 15,000 litres and will be visualised as such on the display.
6.7 – Calculation of the cyclic capacity of a system
Aqua Timer Plus
is able to calculate autonomously the volume of water that the system is capable of treating. The
calculation is carried out using the parameters shown below.
The calculation is carried out automatically after the programming of the hardness, otherwise it can be carried out by
using the code
2C00
.
1000 x A x B
Treatable litres =
C
Where :
A =
Volume of resin in litres
B =
Capacity of ionic exchange of the resin, on average 5 (gr of CaCO
3
/ litre of resin)
C =
Hardness of the water in French degrees [° F]
