Simple, reliable and flexible programmable controller
Suitable for: Commercial pools and spas, water features & water parks
The PC110 Programmable Controller is a versatile solution for ensuring the water quality and chemistry of swimming pools & spas, water features and water parks. It has a user-friendly interface that features multiple timers, sensor inputs, and 6x control relay outputs enabling precise automation of water chemistry.
The unit’s robust design ensures reliable and efficient operation and automatic maintenance of water chemistry. Free chlorine sensor with direct reading in PPM or mg/l, ORP monitoring for sanitizer reference and oxidizer control backup, pH control with a choice of acid/co2 or base feed, as well as TDS control with temperature monitoring.
Key features of the PC110 include:
Remote access: You can control and monitor your pool or spa via our app, from anywhere at any time – using a computer, tablet or mobile device.
pH control: a choice of acid/co2 or base feed. Dedicated setpoint and relay output for both co2 & Acid.
Programmable super-chlorination + chemical savings cycles: The PC110 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.
Display of the Langelier Saturation Index: The Langelier Saturation Index is a measure of the potential for scale or corrosion to form in your pool or spa. The PC110 can display the Langelier Saturation Index so you can easily monitor the condition of your water.
5 Year warranty: The PC110 is backed by a 5-year warranty, which is industry-leading cover for your peace of mind.

PC110 Installation
In our commitment to simplify the installation process of CHEMTROL® controllers, we have streamlined everything onto a customized assembly manifold, prepared for easy connection.
This approach ensures proper water sampling around the sensors, facilitating a hassle-free installation that minimizes the integration work required to get your water treatment system operational.
PC110 – Bypass line assembly
Chlorine sensor (ppm) with integrated pH, ORP, and TDS control
Seamless controller setup: Choose between hardwired dosing pumps or General Purpose Outlets (GPOs) for easy dosing equipment connection.
Our Flow Cell Assembly (FCA) features a clear acrylic flow cell for Chlorine sensor (ppm), 2 flow control valves, a water sample valve, safety flow switch, and probes holder fitting.
The Controller assembly comprises a grey PVC backboard (600×400 mm), while the By-pass line assembly measures (600×500 mm).
CHEMTROL® PC110 – 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 the PC110’s 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.
Setup Menu
Enables full system configuration, including initialization and communication settings. Ideal for adapting the controller to suit various facility requirements.
A Complete Water Management Solution
The CHEMTROL® Programmable Controller is a reliable and flexible solution for commercial pool and facility operators, delivering precise, automated water quality management with built-in safety, scheduling, and diagnostic features.
