Operating Manual
QUICK START REFERENCE
Use this section for reference - please read all safety instructions and
appropriate manual sections for installation and operation instructions.
• Do NOT add chemicals to feeders until all start-up operations are completed.
• Manually adjust and balance pool/spa to acceptable levels and verify using DPD test kit prior
to start-up. Automation should be used to maintain chemical levels, not to balance a pool/spa that is out of acceptable chemical ranges.
On/Off:
- Press the mode button to turn the unit on. Note: ‘FLOW’ light must illuminate.
- Press and hold the mode button to turn the unit off. “OFF” will be displayed in the windows.
To Operate:
- Press and release the mode button until the “AUTO” LED is lit.
- Unit will now operate in the factory preset settings:
- Set levels: ORP1 = 650 mV, ORP2= 640 mV, pH = 7.4
- Feed times: ORP1 & pH = 0.6 second feed with a 5 minute delay ORP2 = OFF
- Limits: ORP1= 900 hi & 100 low, pH= 8.0 hi & 7.0 low Note: ORP limits controlled by ORP1
To Change Settings:
Note: Press and release the mode button until the desired ORP1, OPR2 or pH LED is lit. Once the settings are changed, they will remain at those settings until they are changed again.
- Set level
- Feed time Release the button. The numbers represent the seconds of feed time (all with 5 minute delays). Range is 0.6 to 900 sec. (15 min.). Constant feed is ‘con’. Factory setting is 0.6 sec.
- Hi alert
- Low alert
Manual Feed:
- Press and release the mode button to light the LED associated with the desired feeder to be manually fed, ORP1 , ORP2 or pH.
- Press the “feed once” button. The desired feeder will go through one “set feed” time cycle.
There is no manual feed option when the unit is in constant feed or off.
Other: See the appropriate manual sections for--
- setting the time out feature -calibrating the pH sensor
- changing dip switches (pH/ORP interlock, feeder time out, acid/base, and lockout).
: press the Set Level button until the desired set point is reached. Release the button.
: press the Feed Time button until the desired feed time is reached.
: press the Hi Alert button until the desired level is reached. Release the button
: press the Low Alert button until the desired level is reached. Release the button.

1.0 Safety Instruction

A- WARNING: Do not shut down circulating and control system immediately after using
pool, spa or hot tub. Systems must operate until water chemistry is stable. Systems must be restarted before water chemistry is out of NSPI recommended ranges or water chemistry must be manually corrected.
B- WARNING: Removing power from circulating pump must also remove power from the
controller. Provide a properly located outlet controlled by the circulating pump circuit.
C- WARNING: Pool water must be balanced and stabilized before operating this controller.
(See ‘READ ME FIRST’ document for further information.
D- WARNING: Use a device such as a flow switch to shut-off power from the controller in
the event of pool pump or circulation failure. It is not safe to automatically dispensed chemicals into a circulating system that is not running.
E- WARNING: Controller uses microprocessor.
Wireless communication equipment or other electrical operated devised operated in close proximity may cause inadvertent actuation of chemical feed pumps.
F- WARNING: Risk of electric shock.
Connect power cord to ground-fault circuit interrupter (GFCI). Contact qualified electrician if you can not verify that your installation meets local electrical codes, including grounding of water system components.
G- WARNING: Do not bury cords.
Locate cord to minimize abuse from lawn mowers, trimmers and other equipment. Replace damaged cords immediately. Do not use extension cords.
H- WARNING: Do not install within an outer enclose or beneath skirt of tub or spa unless so
marked.

2.0 Description and Specifications

2.1 General Description

The controller is a microprocessor-based chemical automation system, which continuously monitors and maintains the pH balance and sanitizer level in a swimming pool or spa.
The pH and sanitizer level (ORP) are displayed using sun-bright seven-segment light emitting diodes. The pH and ORP levels are continuously monitored and displayed on the controller’s front panel. The ORP/pH controller has been designed to be user friendly. One MODE button and six SET buttons allow the operator to easily set parameters.
The pH display range is 6.8 to 8.2 with a .1 unit resolution. The pH set point is adjustable from
7.0 to 8.0 in .1 pH steps, with a factory default set point of 7.4 pH. During a pH feed cycle, the pH feed lamp will blink when pH chemicals are being feed and illuminate continuously during the feed delay portion of the feed cycle. The pH Alert lamp will illuminate when the pH reading is higher or lower than the high and low pH Alert set points and prevent the feeding of pH chemicals.
The sanitizer (ORP) display range is 0 to 995 mV with a 5 mV display resolution. The ORP1 set point is adjustable from 400 to 900 mV, with default set point of 650 mV. The ORP2 set point is adjustable from 400 to 890 mV, with default set point of 640 mV. The ORP2 will be 10mV or more below the ORP1.
During an ORP feed cycle, the ORP1or ORP2 feed lamp will blink when sanitizer chemicals are being feed and illuminate continuously during the feed delay portion of the feed cycle. The ORP Alert lamp will illuminate when the ORP reading is higher or lower than the high and low ORP Alert set points and prevent the feeding of sanitizer chemicals.
A manual feed cycle for pH or ORP can be started by pressing the Mode button (placing the controller in stand-by mode for either pH, ORP1 or ORP2) and then pressing the Feed Once button.
The feed cycle is a timed based ‘feed then delay’ system. The controller has a series of fixed feed times (0.6 to 900 sec.) with associated delays as well as a constant feed mode. A feed cycle consists of a feed time plus a delay time. Example, a 30 second feed time followed by a five-minute delay would have a 5½ minute feed cycle. The chemical feeder dispenses chemical only during the feed time portion of the cycle and then waits for a delay period to allow for chemical to dispense throughout the swimming pool or spa.
The controller incorporates an internal non-volatile memory in which all factory default settings as well as field-modified settings are stored. The internal memory is not affected by power interruption and requires no backup battery. Acid/base, pH/ORP interlock, function control and lockout switches are located behind the terminal block access panel.
The pH and ORP outputs are capable of handling 5 amps each at 120 Volt AC. The relay outputs are fused and transient protected. An internal terminal strip is provided for field wiring of the controller. The internal step-down transformer has a class-two energy limiting rating to provide for electrical safety.
NOTE: When automating any body of water, it is essential to size the feeders to reach desired levels in a relatively short period of time. Generally, automating an existing body of water with existing feeders will require the output of the feeders be increased accordingly. If feeders are unable to keep up with demand in a short period of time, automation becomes ineffective.
