The PC7100 controller offers remote access and control, along with data logging and reporting through a user-friendly interface. Enhanced customization options make it easy to achieve precise control over all critical water quality parameters.

Key features of the PC7100 controller:

Remote monitoring and control: The PC7100 can be monitored and controlled remotely via a cloud-based web server. This allows you to access the controller from anywhere in the world, 24/7.

pH control: The PC7100 has a choice of acid/co2 or base feed with dedicated setpoint and relay output for both co2 & Acid.

PPM boost: The PC7100 has both primary and secondary sanitiser setpoints with dedicated relay outputs.

Automatic backwash: The PC7100 features a unique Filter Menu, allowing to effortlessly program backwash schedules for a single or multiple filters based on time cycles or pressure differentials.

UV control: The PC7100 has UV control via 4-20mA or with a dedicated relay output to monitor high combined chlorine (chloramine) levels.

Programmable super-chlorination + chemical savings cycles: The PC7100 can be programmed to automatically perform super-chlorination cycles to shock your pool or spa, or to reduce the amount of chemicals you use by scheduling chemical feed cycles during off-peak hours.

User-friendly screen: The PC7100 has a large, user-friendly screen that gives direct access to all menus and sub-menus. This makes it easy to operate the controller and view the data.

5-year warranty: The PC7100 is backed by an industry-leading 5-year warranty. This gives you peace of mind knowing that your controller is covered for any electronic defects.

Hassle-free installation: The PC7100 comes with a customised manifold that is ready for connection. This makes installation quick and easy.

CHEMTROL® Programmable Controller Overview

The CHEMTROL® Programmable Controller range offers advanced, user-friendly control and monitoring of all essential water quality parameters. Below is a clear breakdown of its key features:


Main Display Screen

Provides quick access to all menus and settings. Operators can navigate using arrow keys and enter values with the keypad — no complex training required.


Sanitizer Menu (Chlorine/Bromine Control)

Controls chlorine or bromine dosing using an amperometric sensor. Operators can set control modes, calibrate sensors, adjust setpoints, and set alarms. Also allows manual or scheduled superchlorination to manage chloramine levels.


pH Menu

Manages pH using either acid, CO2 or base dosing. Includes calibration, control settings, alarm limits, and an Acid Wash program to help maintain sensor accuracy over time.


ORP Menu (Oxidation-Reduction Potential)

Controls ORP levels to ensure effective disinfection. Includes control settings, calibration, alarms, and additional options like Shocking and Chemical Saver Mode for improved chemical efficiency.


Saturation Index & Water Balance Monitoring

The controller continuously calculates and displays the Langelier Saturation Index (LSI) using real-time readings of pH, temperature, alkalinity, and calcium hardness. This helps you maintain proper water balance and provides early alerts to conditions that may cause scaling or corrosion, allowing you to make timely adjustments and protect your equipment.


TDS Menu (Total Dissolved Solids)

Automatically activates the dump valve when TDS or conductivity levels rise above the set threshold. This helps control water clarity and chemical balance.


Temperature / Heater Control

Displays current temperature and controls heaters. Operators can run the heater manually or automatically with a programmable 7-day schedule to save energy and maintain comfort.


Pump and Filter Control

Allows manual or timed control of the main circulation pump and backwash cycle. This ensures consistent filtration and protects equipment such as heaters and sensors.


Setup Menu

Enables full system configuration, including initialization and communication settings. Ideal for adapting the controller to suit various facility requirements.
