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

NOTE: Water flow to the valve can be turned on or bypassed when the controller is powered up for the first time.

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.
