PH/ORP Values:
Press the
Right button
to access the pH and OPR set point values screen. Use the
Up/
Down
button to adjust the pH set point value. Press the
Right button
again to set the ORP set point value.
Press
MENU
to save and return to the previous screen.
pH Set Point:
Displays the current pH set point value. The adjustable range is from 7 to 8
in increments of 0.1. The default pH set point value is 7.5.
ORP Set Point:
Displays the current ORP set point value. Use the
Up/Down button
to
adjust the ORP set point value. The adjustable range is from 650 to 800 in increments of
10. The default ORP set point value is 700 (chlorine level of 3.0 ppm). The ORP set point
is the value that IntelliChem will try to achieve based on the actual chlorine level (ppm).
STATUS:
Displays the current communication link between EasyTouch PL4/PSL4
and IntelliChem via the RS-485 cable.
IChem Comm Error:
Check the RS-485
communication cable is connected to the COM port on the EasyTouch PL4/PSL4 Control
System main circuit board.
Level Gauge indicator:
Press the
Up/Down button
to “fill” the gauge icon so that it
visually represents the same amount of acid available in the container. Press Up/Down
button six (6) times to fill the gauge (three times to half fill the gauge). Six horizontal
bars represent chlorine (or bromine) supply is full. One bar indicates the supply is nearly
empty.
IntelliChem
®
Controller provides the EasyTouch
®
PL4/PSL4 Control System with continual analysis of your
swimming pool water sanitation and pH levels, providing real-time status information to dispense the proper
amount of muriatic acid (pH reducer) and chlorine or bromine for the correct sanitization and pH balance.
IntelliChem controller operates with or without a salt chlorine generator to provide a self-replenishing supply of
chlorine generated from salt. For more information, refer to the IntelliChem Controller Installation and User’s
Guide (P/N 521363).
From the IntelliChem controller menu you can adjust the pH and Oxidation Reduction Potential (ORP)
set point values to meet pool and spa chemistry standards for your pool. A status screen displays a user
adjustable pH and OPR fuel gauge which visually represents the same amount of chemicals available in pH
and ORP container.

Sat Index:
To access the Sat Index settings, press the
Up/Down button
then press the
Right button
. Use the
Up/Down button
to adjust the levels/values for:
CH (calcium
hardness), TDS (Total Dissolved Solids), TA (total alkalinity), CYA (cyanuric acid)
and TMP (current temperature).
Note: See table below for ideal Saturation Index
levels.
SI:
The saturation Index is displayed. IDEAL: Optimum levels. CORROSIVE: pH too low.
SCALING:
Press the
Menu
button three times to return to the main screen.
Note: Use the Langelier Saturation Index (LSI) Calculator to diagnose the water
balance in your pool. Water with a LSI of 1.0 is one pH unit above saturation. Reducing
the pH by one unit will bring the water into equilibrium. To use the LSI calculator, refer to:
