Time of Regeneration
The next value displayed is the Time of Regeneration. It
has a default value of 2:00 a.m. If this is not acceptable,
press the SET button and change the number. Press the
SET button to enter the value. If 2:00 a.m. is acceptable,
press the down arrow (
↓) button.
Hardness
Hardness is the next value displayed. This value is the
water hardness expressed in grains per gallon (milligrams
per liter). The default value is 10 grains/gallon (100 mg/L).
If this is not acceptable, press the SET button and enter a
new value. Any value between 3 and 250 grains per gallon
(30 and2500 milligrams per liter) is allowed. Press the SET
button to enter the new value.
Salt Amount
Salt Amount is the next value displayed. The default value
for Salt Amount is 6 pounds (2.7 kilograms) of salt; refer to
Table 2 for suggested salt settings.
Note: This is the total amount of salt for a regeneration, not
pounds per cubic foot. If 6 pounds is not acceptable, press
the SET button and change the numbers. If 6 pounds is
acceptable, press the down arrow (
↓) button.
Capacity
Capacity is the next value displayed and is expressed in
kilograins (kilograms). Refer to Table 2 for the capacity
setting that corresponds to the resin bed volume and salt
amount. The default value is 1.0 kilograin (0.1 kilogram). If
this is not acceptable, press the SET button and enter a
new value. Any value between 0.1 and 140 kilograins (.01
and 14.00 kilograms) is allowed.
Note: If the calculation for the system capacity exceeds
9999 gallons (99.99 cubic meters) (P5, Capacity, divided by
P3, Hardness,) the control will display 9999 (99.99) for
capacity until the water usage has dropped the remaining
capacity below that number. When water is flowing
through the system, the colon in the Time of Day display
will blink.
At this time, all of the mandatory parameters are filled and
the control is ready for operation. To further increase the
efficiency of the system see P6 and P7 in the Level II
Parameters Section. The display will alternate between the
Time of Day and Capacity if no keys are pressed for
30 seconds. The Capacity value is the volume remaining in
gallons (cubic meters for metric) before a regeneration is
needed.
Verify proper power outage operation by briefly removing
power to the control. The unit will beep and show the time
of day when power is turned on.
If you wish to fine-tune the operation of this control, refer
to Tables 1 and 3 for details concerning allowable values,
defaults, and parameter descriptions. The programming
procedure is the same for all of these parameters.
