# Red Sea ReefControl Lite – Smart Aquarium Controller with pH & Temperature Monitoring

The **Red Sea ReefControl Lite** is the ideal entry point into Red Sea’s intelligent ReefControl ecosystem, providing continuous monitoring, smart alerts and automated control for the essential parameters of your reef aquarium.

Supplied with a **ReefSense digital pH & Temperature Probe**, ReefControl Lite provides accurate, real-time monitoring of pH and temperature straight out of the box. The controller supports **up to 2 ReefSense Probes or Sensors**, allowing you to add an additional sensor such as Salinity, ORP, Temperature, Leak Detection or ATO as your system grows.

Everything is managed through the **Red Sea ReefBeat app**, giving you live readings, historical data, notifications and configurable safe operating ranges from your phone.

## Key Features

* **24/7 pH & Temperature Monitoring**
* **Supports up to 2 ReefSense Probes or Sensors**
* **1 x controllable 12V DC output**
* Real-time monitoring through the **ReefBeat app**
* Custom alerts and safe operating ranges
* Historical logs and trend monitoring
* Digital ReefSense technology for reliable, high-accuracy readings
* Universal ReefSense ports – compatible sensors can connect to any available port
* Calibration information is stored directly on compatible ReefSense probes
* Remote Bluetooth functionality for compatible ReefSense probes
* Compatible with **ReefControl Power** for sensor-based control of AC-powered aquarium equipment
* Compatible with the **ReefControl ATO Module**

## Included ReefSense pH & Temperature Probe

The supplied digital probe continuously measures two of the most important reef aquarium parameters.

**pH**

* Accuracy: ±0.05 pH
* Precision: 0.01 pH
* Automatic temperature compensation
* Double-junction design with dual ceramic external junctions for increased longevity

**Temperature**

* Accuracy: ±0.05°C

Because the sensor electronics are integrated into the probe, measurements are digitised directly at the probe rather than travelling as a traditional analogue signal through the cable.

## Smart Monitoring & Automation

Create rules based on real-time aquarium conditions.

For example, ReefControl can be configured to activate compatible 12V cooling equipment if the aquarium becomes too warm or respond to a Leak Detector when water is detected.

When combined with **ReefControl Power**, ReefSense readings can also be used to control AC-powered equipment such as heaters, chillers and other aquarium devices.

## ReefBeat App Control

The ReefBeat app provides:

* Live parameter readings
* Customisable notifications
* User-defined safe operating ranges
* Historical logs and graphs
* Probe calibration
* Equipment automation and control

ReefControl also operates within the wider **Red Sea ReefBeat ecosystem**, alongside compatible Red Sea smart equipment.

## Expand Your ReefControl Lite

Add one additional ReefSense Probe, Sensor or compatible module depending on your setup, including:

* ReefSense Salinity & Temperature Probe
* ReefSense ORP Probe
* ReefSense Temperature Probe
* ReefSense Leak Detector
* ReefControl ATO Module

For mains-powered equipment automation, add **ReefControl Power**.

## Remote ReefSense Monitoring

Compatible ReefSense probes can also be used away from the ReefControl controller via Bluetooth.

This is useful for checking newly mixed saltwater at a mixing station or calibrating and cleaning a probe away from the aquarium. A **ReefSense USB Power Connector**, sold separately, is required to power a probe when using it remotely.

## What's Included

* 1 x ReefControl Lite Controller
* 1 x ReefSense 2-Port Adapter
* 1 x ReefSense pH & Temperature Probe
* 1 x Single Probe Holder
* Power Supply
