MOTOR
The controller uses a standard 12-volt AC motor that works with either 50 Hz or 60 Hz.
IMPORTANT NOTE
Water fl ow to the valve can be turned on or bypassed when the controller is powered up for the fi rst time.
VARIABLE RESERVE FUNCTION
The AWS metered-demand volumetric controllers are designed to have a variable reserve feature. This feature automatically adjusts the reserve to the end-user’s
water usage schedule.
A variable reserve saves salt and water by only regenerating when absolutely necessary, and ensures enough soft water for typical high-water usage days.
Each day of regeneration the controller reviews the last four weeks of water usage for the same day of the week to determine if the remaining capacity is adequate
for the next day of the week. If not, it will initiate an automatic regeneration.
DISPLAY ICONS
IMPORTANT NOTE
In normal operation and during programming, only a few of the icons will actually be displayed.
1) Days of the week. The fl ag immediately below the day will appear when that day has been programmed as a day the system should regenerated (used with
7-day timer programming).
2) This indicator is displayed when the days between regeneration are being programmed (used with .5 to 99 day regeneration programming).
3) This cursor is displayed when the days between regeneration are being programmed (used with .5 to 99 day regeneration programming).
4) One of these cursors will be displayed to indicate which day will be programmed into the controller
5) “PM” indicates that the time displayed is between 12:00 noon and 12:00 midnight (there is no AM indicator). PM indicator is not used if clock mode is set to
24-hour.
6) When “MIN” is displayed, the value entered is in minutes increments.
7) When “LBS” is displayed, the value entered is in pounds.
8) When “Kg” is displayed, the value entered is in kilograms or kilograins.
9) Four digits used to display the time or program value. Also used for error codes.
10) Colon fl ashes as part of the time display. Indicates normal operation.
11) Locked/unlocked indicator. In Basic User programming this is displayed when the current parameter is locked-out. It is also used in Professional programming
to indicate if the displayed parameter will be locked (icon will fl ash) when controller is in Basic User.
12) When “x2” is displayed, a second regeneration has been called for.
13) The recycle sign is displayed (fl ashing) when a regeneration at the next time of regeneration has been called for. Also displayed (continuous) when in regenera-
tion.
14) The display cursor is next to “SALT” when programming the amount of regenerant.
15) The display cursor is next to “REGEN TIME & DAY” when programming the time of regeneration and the days of regeneration.
16) The display cursor is next to “TIME & DAY” when programming the current time and day.
17) The hourglass is displayed when the motor is running. The camshaft should be turning.
18) These cursors will appear next to the item that is currently displayed.
19) X100 multiplier for large values.
20) Not used.
