7000 Control Start-Up Procedures
Set Time of Day
Press the Set Up and Set Down buttons to set time of day.
— Metric = 24 hour clock
— US = 12 hour clock with PM indicator light
Enter Control Programming Mode
— Press and hold both the Set Up and Set Down buttons for five (5) seconds to enter Programming Mode.
When the program mode is entered, the program dot turns on.
The 7000 controller performs four (4) basic types of Regeneration systems. The type of system is selected by the
system manufacturer and set in the Master Programming Mode. Basic systems are:
• Time Clock
— The control operates for a preset number of days between Regeneration cycles. On the day that a
Regeneration cycle is required the system regenerates at the preset Regeneration Time.
• Meter Immediate
— The control regenerates immediately when the remaining capacity (volume of water that can be treated
before a Regeneration is required) drops to zero (0).
• Meter Delayed
— The control regenerates on the day that the remaining capacity drops to less than the reserve volume.
Regeneration starts at the preset Regeneration Time.

CAUTION
Do not set the time of day to 12:01 PM when entering the
Start-Up programming mode. Doing so causes the
control to enter the Master Programming Mode and alter
the factory settings, resulting in a system malfunction.
