Hydrotech 7000 Valve Automatic Water Softeners Operation Manual - Manual (Page 3)

How Your 7000-DF Water Conditioner Works
Hard water enters your home through the main supply line, enters the softener and passes down through a resin mineral
bed which softens the water. An ion exchange process takes place in which the resin beads capture and hold calcium and
magnesium, the hardness minerals, while the water takes on sodium ions. The soft water then flows into your household
water line.
In normal operation, the Time of Day display will alternate being viewed with the Volume Remaining display. This display
will be in gallons. As treated water is used, the Volume Remaining display will count down from a maximum value to zero
or (---). Once this occurs, a regeneration cycle will be initiated at the Set Regeneration Time. Water flow through the valve
is indicated by the Flow Dot that will flash in direct relationship to flow rate.
Example 833 Gallons of Treated

In regeneration, the control will display a special regeneration display. In this display, the control will show the current
regeneration step number the valve is advancing to or has reached and the time remaining in that step. The step
number displayed will flash until the valve has completed driving into this regeneration step position. Once all
regeneration steps have been completed, the valve will return to Service and resume normal operation.
Example Less than 6 minutes
remaining in Regen
Step #1
Pushing the Extra Cycle Button during a regeneration cycle will immediately advance the valve to the next cycle step
position and resume normal step timing.
Control Operation During Programming
The control will only enter the Program Mode with the valve in Service. While in the Program Mode, the control will
continue to operate normally, monitoring water usage and keeping all displays up to date. Control programming is stored
in memory permanently, eliminating the need for battery back-up power.
