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 ORP set point is adjustable from 400 to 900 mV, with default set point of 650 mV. During an ORP feed cycle, the ORP 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 or ORP) 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.
