Figure 16 Keypad Buttons
1. Time of Day - Press and release to display the time of day
for five seconds. Press button again while current time is
displayed to increment the time 1 minute. Press and hold
for two seconds to rapidly increment the time.
2. Salt Amount - Press and release to display the current
salt setting for five seconds. There are three salt settings;
HC (High Capacity), Sd (standard capacity) and HE (High
Efficiency). Press the button again while the salt setting is
displayed to change the setting.
HC: This setting maximizes the system capacity between
recharges and will also use the most salt. This setting
can be used if you have high water hardness or high water
usage.
Sd: This setting uses moderate amount of salt and provides
a medium amount of water between recharges. This setting
can be used for moderate water hardness or water usage.
HE: This setting minimizes salt usage for a recharge (uses
the least amount of salt) and provides the least amount of
water between recharges. This setting can be used if you
have low water hardness or low water usage.
3. Water Hardness - Press and release to display the current
hardness setting for five seconds. Press button again while
current setting is displayed to increment the hardness by
one. Press and hold for two seconds to rapidly increment
the hardness setting.
A hardness setting too high will cause the system to
recharge more often and use more salt and water than
what is needed to condition your water.
A hardness setting too low will cause the system to
recharge less often. The system may pass hard water
shortly before it recharges.
4. Recharge - Press and release to initiate a recharge. A
recharge will start at the next scheduled time of recharge
(00:00). A flashing regen symbol will be displayed. To stop
a manual recharge press and release the recharge button
a second time. To start an immediate recharge, press and
hold the recharge button for three seconds. A solid regen
symbol will be displayed. The time display will show the
amount of time left in the recharge cycle.
During a recharge cycle (the recharge icon is on steady), a
second manual (delayed) recharge may be called for. Press
the recharge button and release. To stop a second manual
recharge press and release the recharge button a second
time.
During a recharge cycle (the regen icon on steady), a
second manual (immediate) recharge may be called for.
Press the recharge button a second time for three seconds.
A second immediate recharge can not be stopped.
NOTE: If a button is not pushed for five seconds, the
controller returns to normal operation mode.
Pushing the recharge button immediately returns the
controller to normal operation.

recharge, use Table 2. The time remaining is displayed on
the controller. Find the time remaining below your salt
setting. The cycle column will have the cycle number.
• Press and hold Time of Day and Recharge for 3 seconds to
advance through all remaining recharge cycles.
Hourglass will flash.
Camshaft will advance to service - may take 1 to
