Two-Speed Pump Control
The DIG-220 must be wired to control the two-speed main circulation pump and programmed for a Two-Speed pump for this featur
e
to be active (for more
information
on wiring, see page-15 & 16, and for pump control programming, see page-23). The DIG-220 cannot turn off the pump, and can only change pump
speeds, between high
and low (see “Pump Program 1 and 2” on page-23 for additional information) Note - optional pump relay must be installed.
1.
Press Pump.
2.
Press Low Speed.
3.
Pump will switch to low speed.
To switch to “LOW SPEED” when pump is on high speed:
1.
Press Pump.
2.
Press
High Speed.
3.
Pump will switch to high speed.
To switch to “HIGH SPEED” when pump is on low speed:
Basic Operational Programming:
Adjusting the Purifier Output % ...
Press the UP/DOWN arrow buttons to enter the Purifier Adjustment mode. Adjust the purifier output percentage to the desired
output
: from 0% (off) to 100 % (maximum output);
then, press SELECT to default back to the normal display.
At start up of a new system, the standard output setting starting point is 50%.
Typically, once the initial setting is established, very little adjustment is needed
. The
purifier % setting refers to the amount of time the cell is energized within a 15-minute cycle.
The system cycles on-and-o
ff
, as indicated on the display's lower right display.... “ON,” when generating chlorine. Higher settings will generate more chlorine.
Follow the instructions “Purifier % Adjustment Procedure” in the chart on page-19 to determine and correct purifier % settings
.
Example:
50% setting = 50% of 15-minutes or 7.5-minutes ON and 7.5-minutes OFF
.
25% setting = 3.75-min ON, 11.25-min OFF
Once the percentage is set, the DIG-220 will implement the patented temperature compensation algorithm based on current water temperature.
Pump Button Cotinued...
When Boost is activated, and DIG-220 powered through an external time clock or programmer, the time remaining for the boost cycl
e
is held in memory; Boost will
continue
when the pump restarts until the 24 or 72-hr boost period has expired.
If the DIG-220 is controlling the pool pump, the Boost will override the pump program and will run continuously at 100% for
e
ither 24 or 72 hours.
To exit Boost or Super
-
Boost mode and revert to normal operation:
Allow the Boost cycle to expire.
OR press BOOST at anytime to manually deactivate Boost.
Boost or SuperBoost...
The Boost feature is used to increase the purifier % from its normal setting to 100% for a cumulative 24-hour or 72-hour p
eriod w
hen the Boost period expires, or is manually
terminated
,
the Purifier % returns to its previous setting and normal operation.
Boost Purifier Output to 100% for 24-Hours...
From the normal operation mode, press and release the BOOST button. The display will flash:
"
Boost 24-hour,"
then
“
Boost hh
” (with the
“hh”
actually being the displayed hours remaining in the boost period).
Boost Purifier Output to 100% for 72-Hours...
From normal operation mode, press and hold the BOOST button unti
l:
"B
oost 72 hour ON”
is displayed; then release
the BOOST button. Display will then show “
Boost hh
” with the
“hh”
actually being the displayed hours remaining in boost period.
For the first two weeks, test the water chemistry parameters every 3-4 days. Adjust chemicals as needed to maintain correct
water balance. For the Free Chlorine adjustment,
use
the following table for fine-tuning the controller output percentage (%):
2
Add the proper amount of salt as indicated by the DIG-220 (or as described on page-24), and run the circulation pump continu
ou
sly for 24-hours allowing the salt to be fully
mixed and dissolved into the pool.
If
the salt level is too low, the DIG-220 will provide a warning, and will not generate chlorine until the minimum salt level has been r
eache
d.
3
Use the UP and DOWN arrow buttons to set the purifier % to 50%, and then allow the pool to operate normally
.
After the optimal output percentage (%) has been determined, this setting will not normally require further adjustment.
Rather to c
ompensate for increased bather usage or heavy
rainfall
s
(which can both quickly consume chlorine), select a Boost Cycle.
FIG-21
Purifier Mode
The DIG-220 will automatically display informative messages about the condition of the chlorinator (Purifier Output %, water te
m
perature, warning messages, etc.), and
responds
to manual adjustment of purifier % setting (as described below).
After 30 minutes of inactivity, the display will go to a walking dot screen saver mode. All functions
such as chlorine
generation, reverse, boost, etc., will continue in the background. Pressing any key will call up the normal informational display.
Purifier % Adjustment Procedure:
1
Balance water chemistry according to necessary water chemistry parameters. (See page-24 & 25.) For new start ups, if free clorine level as tested is not at least 1 ppm,
add
liquid chlorine to
e
nsure a 1 -3 ppm free chlorine reading.
Purifier % Currently set to:
If Free Chlorine is lower than ideal range...
If Free Chlorine is higher than ideal range...
0% - 25%
25% - 100%
The purifier % output needs to be increased.
The purifier % output needs to be reduced.
The purifier % output needs to be reduced.
The purifier % output needs to be increased.
Use the
UP
arrow button to increase the purifier output %
.
- If not done already, set purifier % to lower value.
- Power level may be too high and may need to be adjusted down.
-
If not done already, set purifier % to higher value.
-
If at 100%, power level may be too low and need to be raised
and/
or cell size increased. - Check sizing
.
Use the down arrow button to decrease the purifier output %.
