Programming
On If pH>: Acid Feed: the set point value at which the Controller will begin to feed acid or other pH chemicals to the water
source. Set this value to zero if not using acid to control the pH.
On If pH<: Base Feed: the set point value at which the Controller will begin to feed base or other pH chemicals to the water
source. Set this value to zero if not using base to control the pH.
Off if RLy on(#): Number of relay (1 or 2) will display. Depending on which relay is on the other relay will remain off. Prevents

Min Time Off: Minimum amount of time that the Controller will be off before it will dispense any more chemicals, regardless
of the set point reading.
Off if Sw_Off: Tells the Controller not to dispense any chemicals if this switch number is in an OFF condition. This prevents a
large amount of chemicals from being added into the water line as flow of water returns.

reading screen will display a “SOV” (Set Point Overfeed) on relay display. (This is to keep the Controller from continuously
feeding chemicals in case the sensor has a problem or if there is a clog in the feed tubes or you run out of chemicals). This
control condition will automatically reset itself if the sensors set point value is reached.
Overfeed:Thisvalueshouldbesetforthemaximumaccumulated“ON” time that the Controller will be allowed to feed each

Controller will disable the associated feed relay, and not feed any more of that chemical until the overfeed timers are cleared
manually, or until the Controller automatically resets the overfeed timers at the end of its 24 hour day. Each relay output used

condition. If the overfeed time alarm condition persists over a few days you may need to check the chemical container levels,
Controller feeder problems or you may need to increase the overfeed time to a level that will allow the Controller to maintain
the water quality levels within your specified limits. If the system does go into an overfeed condition along with the alarm LED
coming on, it will also display an "OVR" statement in the display screen, for the relay output that was in an overfeed condition.
Overfeed for 01:15:00 or 01:30:00, in case there was a problem with the feeder, chemicals or the sensor that are in overfeed
condition, the Controller would disable feed and alert a problem.
NOTE: The Controller's Overfeed feature is equivalent to the amount of time the chemical feeders will feed during
an alarm condition.
