PROGRAMMING
Pump Button Cotinued...
Pump Button - 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 feature 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.
To switch to "LOW SPEED" when pump is on high speed:
1. Press Pump.
2. Press Low Speed.
3. Pump will switch to low speed.
To switch to "HIGH SPEED" when pump is on low speed:
1. Press Pump.
2. Press
3. Pump will switch to high 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-off, 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, 1 1.25-min OFF
Once the percentage is set, the DIG-220 will implement the patented temperature compensation algorithm based on current water temperature.

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 period when 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 until: "Boost 72 hour ON" is displayed; then release
the BOOST button. Display will then show " B oost hh" with the "hh" actually being the displayed hours remaining in boost period.
When Boost is activated, and DIG-220 powered through an external time clock or programmer, the time remaining for the boost cycle 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 either 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.

Purifier Mode

The DIG-220 will automatically display informative messages about the condition of the chlorinator (Purifier Output %, water temperature, warning messages, etc.), and
responds to manual adjustment of purifier % setting (as described below).
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 ensure a 1 -3 ppm free chlorine reading.
2 Add the proper amount of salt as indicated by the DIG-220 (or as described on page-24), and run the circulation pump continuously 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 reached.
3 Use the UP and DOWN arrow buttons to set the purifier % to 50%, and then allow the pool to operate normally
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 (%):
Purifier % Currently set to:
The purifier % output needs to be increased. Use the UP
0% - 25%
- If not done already, set purifier % to higher value.
25% - 100%
- If at 100%, power level may be too low and need to be raised
and/or cell size increased. - Check sizing
After the optimal output percentage (%) has been determined, this setting will not normally require further adjustment. Rather to compensate for increased bather usage or heavy
rainfalls (which can both quickly consume chlorine), select a Boost Cycle.

After 30 minutes of inactivity, the display will go to a walking dot screen saver mode. All functions
- If not done already, set purifier % to lower value.
- Power level may be too high and may need to be adjusted down.
