CONTROLLER FEATURES
CHEMTROL
®
PC Controllers are microprocessor-based
programmable controllers designed for automatic control of
water chemistry, water balance and filtration in swimming
pools, spas, cooling towers and industrial applications.
New Features
This manual introduces two new features:
- On-screen data display, available on all models,
- New solid state PPM sensor for Free Chlorine, available
with PC5000 and PC7000 controllers.
Models
Five different, yet very similar, CHEMTROL
®
controller models
are covered in this manual: PC2100, PC3000/PC5000, and
PC6000/PC7000. The latter 4 models use similar hardware
and thus are referred to as PC3000 Product Line.
Please refer to Figure 1 showing the standard features and
available options for each model. Note that these models have
few differences and can do mostly all the same functions
based on how they’re equipped. While PC2100 lacks level and
filtration control capability for example, PC5000/PC7000 only
have Free Chlorine control included when compared to their
otherwise identical counterparts PC3000/PC6000, respectively.
Automated Water Treatment
CHEMTROL
®
PC controllers are advanced automation
systems for water maintenance. Designed around a
sophisticated microprocessor, the controllers display user-
friendly menus and submenus on an easy-to-read LCD (Liquid
Crystal Display) screen. All the displays and adjustments are
accessible from menu screens that are laid out in a logical and
intuitive order. They can in fact be used without reference to
the instruction manual.
All sensing devices are connected to the central control
module. That makes it possible to monitor the status of all
operational parameters at a glance. Also, in case of
malfunction or alarm, the operator is immediately alerted.
A 24-hour clock/calendar shows the date and time on the main
screen.
Control Functions
The following display and control functions are:
- Oxidation-Reduction Potential (ORP or Redox) in
millivolts with programmable oxidizer feed, superoxidation
and chemical savings program,
- Sanitizer Concentration in parts per million (ppm) or
milligrams per liter (mg/l) with programmable sanitizer feed,
superchlorination and chemical savings program,
- pH from 0 to 14 with capability for acid and base feed,
- Conductivity in microsiemens/cm or Total Dissolved
Solids (TDS) in ppm or mg/l with capability for programmed
dumping and replacement of water and for addition of three
different chemical additives, such as inhibitor, different
biocides or probe cleaner.
- Heater Control with temperature display in Fahrenheit or
Celsius, programmable heater control, and energy savings
program.
- Water Recirculation with automatic programming or manual
control of main pump, plus display of flowrate in gallons per
minute (gpm) or liters per minute (l/m) and cumulative flow in
Millions of Gallons (Mga) or cubic meters (m3),
- Water Balance and Saturation Condition derived from the
Langelier Saturation Index and showing water balance
conditions as either OK, corrosive or scaling.
- Filtration with display of inlet and outlet pressures and
programmable filter backwashing (PC6000/PC7000 only)
based on choice of time, inlet pressure, pressure differential
or combinations of the above.
