Displaying and altering program values
The main program values can be displayed
and altered if required by pressing a key.
Hardness of supply water /
filter capacity
Press the key with the symbol . In the case
of an ion exchanger the bottom line will show
the present supply water hardness, for a filter
system it will show the capacity entered. (see
program step 10.3).
If you wish to change the value shown, use the
‘ ‘ key to move the cursor under the figure to
be changed, and change the value with the
number key ( ‘#’).
The following values may be entered,
according to the units entered at phase 10.3 of
the basic programming:
Unit of the supply
water hardness :
entry value :
°D
2 - 99
°F
4 - 199
°E
2 - 99
mg/l CaCO3
40 -1999
gpg
2 - 99
no unit
0,01 - 9999,99 m3
(0,02 mmol/l = 0,10°D = 0,13 °E =0,18 °F
= 1,79ppm = 0,11gpg(USA) = 0,13gpg(UK))
The calculation of the soft water quantity with
altered values is carried out at the start of each
regeneration using the formula:
NOTE: In the case of remote control valves
with water supply by-pass ports, the water
meter records the dilution amount. The
hardness of the diluted water must therefore
be subtracted from the value to be entered.
Example :
Supply water hardness = 15 °D
Diluted water
= 6 °D
This gives an input value of :
15 °D – 6 °D = 9 °D
Current time
Press the time key with the symbol . The
current time appears in the lower line.
If you wish to change the value shown, use the
‘ ‘ key to move the cursor under the digit to be
changed, and change the value with the
number key ( ‘#’).
