Key Features
Easy Setup
Designed for classic T-style salt system or for new pool installations,CQ2 reduces pipe cutting,re-piping, and equipment repositioning and a cleaner installation-subject to on-site installationconditions.
Easy Retrofit Installation
Engineered to replace common split-type salt chlorinators. Compatibleinterfaces and dimensionsreduceinstallation changes, enabling quick andhassle-free upgrades.
Multiple Capacity Options
Available in arange of capacities to suitresidential and light commercial pools,making it easy to select the right modelfor any application.
Built-in Power Supply
Integrated power supply accepts100-240V AC, 50/60Hz directly,eliminating the need for an externalpower adapter and ensuring worldwidecompatibility.
Single Integrated Main Harness
A single integrated harness connects thecontroller and cell, reducing cable clutterand on-site wiring. Water qualitymonitoring devices connect directlythrough the cell interface for acleanerinstallation.
Automatic Cell Recognition
Automatically detects the connected celland applies the correct operatingparameters, simplifying installation andcommissioning while minimizing setup errors.
Designed for Global Markets
Supports metric and imperial units, withclear display of pool volume, watertemperature,salinity,and salt levelrecommendations for convenientoperation worldwide.
Easy Care
CQ2 adjusts chlorine output based on water conditions salinity changes, and system status-reducing manual intervention and making pool care easier
Intelligent ORP Control
Automatically adjusts chlorine outputbased on ORP readings for stabledisinfection. Manual and scheduledmodes also available.
Wide-Range Salinity Adaptability
CQ2 automatically adapts to a widerange of salinity levels. If rain dilutesyour pool water, the system adjustsoutput, protects the cell, and promptsyou when it’s time toadd salt.
5-stage ChlorineOutput(20%-100%)
Flexible adjustment based on poolsize, season,and usage -fromroutinemaintenance to shock chlorination.
Wi-Fi& App Control
Built-in Wi-Fienables real-timemonitoringof system status, water temperature, andsalinity via the App.Remotely adjust settingsand receive maintenance and alarmnotifications-keeping you connected toyour poolanytime,anywhere.
Flexible pH Management
With a pH probe, the system enablesfull pH monitoring and control. Withoutone, it intelligently analyzes ORPsalinity,current, and operating trendsto flag potential water quality issuesbefore they arise.
Smart Device Integration
Links with pumps, automatic poolcovers, and other external devices forcoordinated control-reducing manual effort.
Easy Ownership
Clear status.Timely maintenance.
CQ2 tracks cell status and life, sends timely maintenance alerts, and features a replaceabtle cell – making long-term maintenance easier
Cell Life Management
Records runtime and status data, giving usersreducing reliance on guesswork.
clear visibilty into the health of key components –
End-of-Life Alert
Pravides timely notifications as the cellapproaches the end of its service life, enablingplanned maintenance or replacement andminimizing unexpected downtime.
Independent Cel Replacement
Cell can be replaced separatelyreplacng the entre unit.
-lowering long-term maintenance costs without
Cleaning Reminder
Reminds users to inspect and clean the cellbased on operating time and system status,heiping maintain optimal chlorine production.
Abnormal Status Alerts
App displays critical status information.helping users identify issues quicky and respondprompty.
OTA Online Updates
Supports over-the-air (OTA) firmware updates,delivering new features, performanceenhancements, and continuous productimprovements.
Smart Algorithms
Smart Algorithms, Easy Pool Care.
Powered by Smart Algorithms, CQ2 synthesizes multiple signals – not a single reading t auto-adjusts chlorine output, protects the cell and reminds
you when salt, cleaning, or maintenance is needed.
Sense
Continuously monitors key pool parameters,including salinity, water temperature, flow, ORP,cell status, and operational trends.
Decide
Analyzes real-time data to determine chlorinedemand, optimize output, and identify conditionsrequiring user attention.
Execute
Automatically triggers chlorine production,adjusts output, protects the cell, and promptlynotifies the user via App when salt addition,cleaning, or maintenance is required.
More Than App Control
Powered by Smart Algorithms, CQ2 handles automatically routine decisions, output adjustments, and reminders. Nomore guessing water conditions or frequently adjustchlorine output by hand. CQ2 responds to systemconditions and reminds you when salt, cleaning, or maintenance is needed, making everyday pool care simpler and more hassle-free.
