GROC Programming
Program Data Input
There are a few items to note that can make programming the Culligan
®
Global Reverse Osmosis Controller (GROC)
easier:
Slew Rates This term refers to the speed at which the display moves through the input of material. For ex-
ample, holding down the up arrow key for (5) seconds when inputting minutes for Time of Day
will cause the minutes to pass in (10) minute blocks of time. Press the up arrow or down arrow
keys for shorter periods (less than 5 seconds) will slow the rate. To move through the program-
ming slowly, do not hold down the up arrow or the down arrow keys.
Beeper A beeper is available to assist the user by providing an audible tone (about 70 decibels) to signi-
fy valid (one beep) and invalid (three beeps) key presses. The beeper can be deactivated in the
programming mode. (If error occurs, beep will still sound even if set to “No” programming.)
Programming
Mode Timeout
If there is no keypad activity for a one (1) minute period while in the programming mode, the
controller will exit the programming mode and return to the main display. Any setting that was
changed prior to the control timing out will revert to the original value. Pressing the CHECK
MARK button saves the setting.
Program Input
Acceptance
For programming information to be accepted, the check mark key must be depressed prior to
programming mode timeout.
NOTE The following programming section is used for the G1, M2, G2 & G3 RO systems. The controller used
on the G1 & M2 RO units have the same programming but the controller has fewer features. Unless
otherwise specified, the programming is applicable to all units. Features not available on the G1 and
M2 are noted with a double-cross symbol (‡).
