# Red Sea ReefControl Lite – Smart Aquarium Monitoring & Control

The **Red Sea ReefControl Lite** is the ideal entry point into Red Sea's intelligent ReefControl ecosystem, providing accurate 24/7 monitoring, smart notifications and automated control of essential reef aquarium equipment.

Supplied with a **ReefSense digital pH & Temperature Probe**, ReefControl Lite provides continuous monitoring of two of the most important reef aquarium parameters straight out of the box.

The controller supports **up to 2 ReefSense digital Probes or Sensors** and includes **1 x controllable 12V DC output**, making it perfect for reef keepers who want reliable monitoring today with the ability to expand their system later.

Everything is managed through the **Red Sea ReefBeat app**, allowing you to view live readings, set safe operating ranges, receive notifications, review historical data and create automated control rules directly from your phone.

## Key Features

* 24/7 real-time aquarium monitoring
* pH & Temperature monitoring included
* Supports up to **2 ReefSense Probes or Sensors**
* **1 x 12V DC controllable output**
* Real-time monitoring through the ReefBeat app
* Custom safe parameter ranges
* Instant alerts and notifications
* Historical logs and trend graphs
* High-accuracy digital ReefSense technology
* Universal ReefSense connections
* Semi-automatic probe calibration through ReefBeat
* Calibration information stored directly on compatible probes
* Remote Bluetooth probe functionality
* Compatible with ReefControl ATO Module
* Compatible with ReefControl Power for AC equipment automation

## Included ReefSense pH & Temperature Probe

The supplied **ReefSense pH & Temperature Probe** continuously monitors both pH and temperature using integrated digital electronics.

### pH

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

### Temperature

* Accuracy: **±0.05°C**

Unlike traditional analogue probes, the electronic sensors are integrated directly into the ReefSense probe, so readings are digitised before being transmitted to the controller.

This provides accurate and reliable monitoring while reducing the possibility of electrical interference affecting the reading.

## Smart Monitoring & Automation

ReefControl Lite does more than simply show aquarium parameters.

Custom rules can be created using ReefSense readings to automatically control compatible equipment connected to the controller's 12V DC output.

For example:

* Activate a cooling fan if aquarium temperature becomes too high
* Control a small DC pump or solenoid
* Respond to water-level readings when using the ReefControl ATO Module
* Trigger safety actions when using a ReefSense Leak Detector

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

## ReefBeat App Integration

ReefControl Lite connects with the **Red Sea ReefBeat ecosystem**, giving you centralised control and monitoring from your phone.

The ReefBeat app allows you to:

* View live sensor readings
* Define preferred and acceptable parameter ranges
* Receive notifications when readings move outside your limits
* Review minimum, maximum and average readings
* View historical trends and graphs
* Calibrate compatible ReefSense probes
* Configure 12V DC equipment
* Create sensor-based automation rules
* Monitor connected ReefBeat equipment

ReefControl integrates with the wider ReefBeat ecosystem, including compatible **ReefLED, ReefWave, ReefRun and ReefMat** equipment.

## Expand Your ReefControl Lite

The ReefControl Lite supports a maximum of **2 ReefSense devices**, so in addition to the included pH & Temperature Probe you can add another compatible ReefSense Probe, Sensor or module.

Compatible options include:

### ReefSense Salinity & Temperature Probe

Provides continuous salinity and temperature monitoring.

Salinity values can be displayed as:

* PSU / ppt
* mS
* Specific Gravity

Salinity accuracy: **±1%**

Temperature accuracy: **±0.05°C**

### ReefSense ORP Probe

Provides continuous monitoring of your aquarium's oxidation-reduction potential.

ORP accuracy: **±30mV**

ORP precision: **1mV**

### ReefSense Temperature Probe

Titanium-tipped dedicated digital temperature probe.

Temperature accuracy: **±0.1°C**

### ReefSense Leak Detector

Detects freshwater and saltwater spills and can be incorporated into automated safety routines.

### ReefControl ATO Module

Adds a fully featured Automatic Top Off system directly to ReefControl without requiring another controller.

The ATO Module connects its digital water-level sensor and DC ATO pump directly to ReefControl.

## Remote Bluetooth Probe Use

Compatible ReefSense probes can also be temporarily used away from the ReefControl controller through Bluetooth and the ReefBeat app.

This is ideal for tasks such as:

* Checking newly mixed saltwater
* Testing pH at a mixing station
* Checking salinity before a water change
* Cleaning probes
* Calibrating probes away from the aquarium

Remote readings are instantaneous and do not interfere with your aquarium's historical trend data.

For independent remote use, the probe can be powered using the optional **Red Sea ReefSense USB Power Connector** and a compatible USB power source or power bank.

## 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**
* **1 x Power Supply**

The Single Probe Holder features adjustable height and fittings for standard 12mm and 18mm diameter probes and clips onto aquarium or sump glass approximately 4–12mm thick.

## ReefControl Lite Specifications

**Maximum ReefSense Devices:** 2
**Included Monitoring:** pH & Temperature
**12V DC Outputs:** 1
**Control App:** ReefBeat
**Bluetooth Probe Support:** Yes

## Who Is ReefControl Lite For?

The **ReefControl Lite** is ideal for reef keepers who want accurate pH and temperature monitoring with smart alerts and automation without immediately requiring a large multi-probe system.

Start with the included pH and Temperature Probe, add the additional ReefSense sensor most important to your aquarium, and expand into ReefControl Power or ATO control when your system requires it.
