GENERAL 706W SERIES INSTRUCTIONS

706W Series Controller
Power Loss Memory Retention
The 706W Series controllers feature battery-free time and
date retention during the loss of power. This is designed to
last a minimum of 8 hours depending on the installation.
The controller will continue to keep time and day in dynamic
memory while there is no AC power.
The controller will not track water usage in the event of a
power failure.
All programmed parameters are stored in the 706W Series
static memory and will not be lost in the event of a power
failure. These settings are maintained separately from the time
and day settings.
Motor
The 706W series controller uses a standard 12-volt AC
50/60 Hz motor.
Power
706W Series controller is available in 50/60 Hz power
configuration:
Information entered or calculated by the controller is stored in
two different ways.
1. A static memory will store:
User programmed values
Salt setting (salt setting)
Hardness setting
Daily averages (history values)
2. A dynamic memory with 8 hour retention will store:
Time of day
Today's water used
Variable Reserve Function
The 706W Series metered-demand volumetric controller
is 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 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 the remaining capacity is not adequate, it will initiate an
automatic recharge.
NOTE: Water flow to the valve can be turned on or bypassed
when the controller is powered up for the first time.

at the next time of recharge has been called for. Also
displayed (continuous) when in recharge.
7. When "x2" is displayed, a second recharge has been called
for.
