Ultramax Controller
Power Loss Memory Retention
The Ultramax 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 on volumetric demand controls in
the event of a power failure.
All programmed parameters are stored in the Ultramax 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 Ultramax series controller uses a standard 12-volt AC motor that
works with either 50 Hz or 60 Hz. The same motor is used worldwide and
does not need to be changed for different power conditions.
Controller Memory
Information entered or calculated by the controller is stored in two
different ways.
A static memory will store:
Model number
Regenerant setting
Time of regeneration
Days between regeneration
Filter mode
A dynamic memory with 8 hour retention will store:
Current day of week
Running clock
Variable Reserve Function
The Ultramax metered-demand volumetric controllers are designed with 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.
NOTE:
Water flow to the valve can be turned on or bypassed when the
controller is powered up for the first time.
