ReefControl Pro/Lite does two jobs at once: it monitors your aquarium and it controls your equipment.

Monitoring. Connect any combination of ReefSense Probes & Sensors to the ReefSense port. Each one reports its readings to the ReefBeat App in real time, builds a 30-day log, and can send you notifications. You set a Desired range and an Acceptable range for each parameter so the app knows what “normal” looks like for your tank.

Control. ReefControl Pro/Lite can switch equipment on and off automatically based on those readings:
1. Onboard 12 VDC ports – directly control DC equipment such as cooling fans, solenoids or DC pumps (one port on Lite, two on Pro).
2. AC equipment, via ReefControl Power – pair a ReefControl Power and the same Probes & Sensors can control mains-powered equipment such as heaters, chillers and ozonizers in its AC sockets.

Each output can be set to Always On, Always Off, a daily Schedule, or controlled by a Probe or Sensor (for example, “switch the cooling fan ON if the temperature rises above 28 °C / 82.4 °F”). One Probe or Sensor can control any number of outputs, each with its own settings.

All of Red Sea’s connected devices are operated via the ReefBeat App, which must be installed on a mobile device with an internet connection (including tablets). See the full list of supported mobile devices on our website.

Through your personal user account on the cloud, ReefBeat lets you set up and manage any number of aquariums and add multiple devices to each of them. It guides you through setting up your account, your aquarium(s) and your Red Sea connected devices, and is where you read parameters, set ranges, calibrate probes, configure equipment control, view logs, and manage notifications.

For full functionality, the device must have a permanent connection to the internet through your home Wi-Fi network. In this mode you will be able to see the current status of your ReefControl Pro/Lite, change settings, and receive notifications on your mobile whenever you have access to the internet.

The ReefBeat homepage shows the current status of all your connected devices and links you directly to the settings page of each unit.

You can install ReefBeat on multiple mobile devices by entering the same user account details. All mobile devices will have the same rights for operating and changing the settings. Keep this in mind before giving your user details to any third party.

If you do not have a home network, or your home network does not have an active internet connection, you can connect and control your ReefControl Pro/Lite in Offline or Direct Mode. However, certain functionality such as remote access, multiple mobile devices and status notifications will not be available.

ReefBeat is constantly under development. For the most up-to-date operating instructions, view or download the latest user guide from the Red Sea website at www.redseafish.com.

App navigation in this manual is shown as a breadcrumb, for example: Homepage > Main Menu > My Aquariums > …

Locate the ReefControl Lite or Pro controller in a convenient position and attach it with the mounting bracket, using the screws or the adhesive tape provided. The controller is designed to operate in a humid environment, but it is not waterproof – choose a dry location and take care whenever removing it from the bracket. Every connector port has a rubber cover that should be left in place on any port that is not in use.

Steps

Mount the controller on its bracket, above any possible water level, with easy access to the buttons.
Connect the ReefSense port connector cable (2-port for Lite, 4-port for Pro) to the ReefSense port, and locate the connector near the sump using the wall-mount or sump-mount bracket. The connector is rated IP67, but leave the rubber covers on any unused ports.
Connect each ReefSense Probe/Sensor to the connector, making sure the securing nut is fully closed for a stable, waterproof connection, and position each one as appropriate for its type (see Operation).
Connect any 12 VDC devices to the port(s). Each port’s default state is “Always Off” until you configure it in the app.
If you are pairing a ReefControl Power, connect it to the ReefControl Power pairing port using the cable supplied with ReefControl Power, with the securing nut fully closed.
Arrange every device cable into a drip loop (see Safety).
Connect the supplied 12 V power supply.

1. Download and install the ReefBeat App from the App Store or Google Play, as appropriate for your mobile device. (In countries without access to Google Play, an APK file and installation instructions can be downloaded from Red Sea’s website.)
2. After installing ReefBeat, you will be guided through setting up your ReefBeat user account and aquarium(s). Account details can be edited only while your mobile is connected to the internet. You can then start adding your Red Sea connected devices.

3. For full functionality, set your aquarium to “Online.” If you do not have an available Wi-Fi network at your aquarium, set it to “Offline.” You can change this later when Wi-Fi becomes available.
4. If you have set up more than one aquarium, select the aquarium from the dropdown menu at the top of the screen before proceeding.
5. Set the ReefControl Pro/Lite to AP (Access Point) mode by pressing its Settings button for 5 seconds (until it double-blinks); the Settings LED will blink.
6. Go to Homepage > Main Menu > Device Manager and tap Add Device, select the icon for the ReefControl Pro/Lite, and follow the instructions in the app. This may take a few seconds. If no devices appear on the list, check that the unit is in AP mode and/or refresh the page.

7. ReefBeat will display a list of Wi-Fi networks available to the unit. Select your preferred network and wait while the device connects to it; the Settings LED then turns solid.
8. If you have set the aquarium to Offline, select the “Direct Mode” option at the top of the screen to skip the network connection; the Settings LED keeps blinking as the unit stays in AP mode.
9. Give the device a name (up to 30 characters) and follow the remaining on-screen instructions. Once the device is connected, you will be directed to the settings page, ready to set up any connected Probes, Sensors or 12 VDC devices.

Your ReefSense Probes, Sensors & Modules

ReefControl Pro/Lite works with the full range of ReefSense Probes & Sensors, plus the ReefControl ATO Module – each with its own manual:
• pH & Temperature Probe – pH and temperature. See the ReefSense pH & Temperature Probe manual.
• Salinity & Temperature Probe – salinity and temperature. See the ReefSense Salinity & Temperature Probe manual.
• ORP Probe – ORP (REDOX). See the ReefSense ORP Probe manual.
• Temperature Probe – temperature only. See the ReefSense Temperature Probe manual.
• ATO Sensor – water level (with built-in temperature) for automatic top-off. See the ReefSense ATO Sensor manual.
• Leak Detector – detects spilled water. See the ReefSense Leak Detector manual.
• ATO Module – complete auto top-off: an ATO Sensor with a matched pump, tubing and siphon breaker. See the ReefControl ATO Module manual.

The sections below cover how ReefControl Pro/Lite works with any Probe or Sensor – connecting and adding them, setting parameter ranges, logging, notifications and using their readings to control your equipment. For anything specific to a particular Probe or Sensor – placement, calibration and maintenance – see its own manual above.

Setting up ReefSense Probes & Sensors

Any combination of ReefSense Probes & Sensors can be connected to the ReefSense port – up to 2 on ReefControl Lite and up to 4 on ReefControl Pro (up to 7 on the Pro with the ReefSense 4 port expander). You can even run several of the same type.

Placing a Probe or Sensor

Position each Probe or Sensor as described in its own manual. In general, pH, Salinity, ORP and Temperature Probes sit in the aquarium or sump where there is good water flow, with the sensing tip immersed at all times; the ATO Sensor monitors the top-off level (for example in the sump’s return chamber); and the Leak Detector stands upright, with its titanium pins pointing down, where water would collect first. Each manual also covers any probe-specific steps – such as removing a storage cap or fitting the snail guard – so follow it for placement details.

Connecting and adding a Probe, Sensor or module

Add your Probes, Sensors and the ATO Module one at a time, finishing each in the app before connecting the next – and connect only one Probe of a given type while you set it up, so the app configures the right one.

1. Connect the Probe or Sensor to the ReefSense port connector cable, making sure the securing nut is fully closed for a stable, waterproof connection. (The ATO Module’s level sensor connects to the ReefSense port in the same way; its pump connects to a 12 VDC port – see the ReefControl ATO Module manual.)
2. In the app, open your ReefControl Pro/Lite and choose Setup Probe, then select its type – Temperature, pH & Temperature, Salinity & Temperature, ORP, ATO & Temperature, Leak Detector, or ATO Module.
3. The app shows the ID of the Probe it has found so you can confirm you’re setting up the right one, then continue. (If the app doesn’t detect the Probe, check the connection and try again.)
4. If a newer version of the Probe’s firmware is available, the app updates it before continuing over Bluetooth. Keep your phone within approximately 3 m (10′) of the Probe and leave the app open during the update, which may take a few minutes.
5. Give the Probe a name, or keep the default. (If you have more than one Probe of the same type, the app numbers them in the order you add them; you can rename any Probe later in its settings.)
6. Set the parameter ranges (see Parameter ranges), and choose whether to activate the audible alarm for this Probe.

Repeat for each additional Probe or Sensor.

Parameter ranges (Desired / Acceptable / Danger)

For each parameter, you tell ReefControl Pro/Lite what “normal” looks like for your aquarium by setting two ranges. Anything outside the Acceptable range is then treated as the Danger range:
• Desired (green) – your target range.
• Acceptable (orange) – still fine, but drifting away from the target.
• Danger (red) – any reading outside the Acceptable range. You don’t set this yourself; it’s whatever falls beyond the Acceptable range, and it’s when you’ll want to know straight away.

When you set up a Probe, the app pre-fills recommended values for the Desired and Acceptable ranges that you can adjust to suit your tank; you enter the boundary value for each. (Choosing to skip simply keeps the recommended values, which you can edit later.) Your readings are then shown against these ranges on the homepage and in the graphs. You can choose, for each parameter, to be notified when a reading enters its Danger range, and you can switch on the audible alarm for that Probe; it is then enabled whenever a reading is outside the Acceptable range.

Remote probe use (Bluetooth)

Any ReefSense Probe can be used away from ReefControl Pro/Lite, communicating with the ReefBeat App directly over Bluetooth – handy for a quick reading at your mixing station, or for cleaning and calibrating at a sink. It uses the optional ReefSense USB-C connector to power the Probe and switch on its Bluetooth, and readings taken in remote mode are not added to your logs. The full step-by-step is in each Probe’s own manual.

Controlling 12 VDC Ports

ReefControl Pro/Lite’s onboard 12 VDC ports directly power and control DC equipment such as cooling fans, solenoids and DC pumps – one port on ReefControl Lite, two on ReefControl Pro. Each port is variable, so you can run its device at a set speed or strength.

The ports use the same bespoke connector as Red Sea’s ATO pumps, so a Red Sea DC pump connects directly. To connect any other 12 VDC device, use the 12 VDC accessory cable (R35839), which ends in a standard 5.5 × 2.5 mm male DC jack. If that jack doesn’t suit your device, cut it off and wire the cable to the device directly – the red wire is positive (+) and the black wire is negative (-).

Setting up a 12 VDC device

1. Connect the device to a 12 VDC port, with the securing nut fully closed – directly for a Red Sea pump, or using the 12 VDC accessory cable for any other device. On the Pro, note which port you used (Port 1 or Port 2).
2. In the app, add the device to that port and give it a name.
3. Set the intensity (0-100 %) at which the port runs the device – for example, to set the speed of a DC pump or fan. (The default is 100 %.)
4. Choose how the port is controlled:
• Always ON
• Always OFF
• Schedule – the port runs during the daily ON periods you set.
• Controlled by a Probe or Sensor – the port switches automatically in response to a reading (for example, a Temperature Probe running a cooling fan when the water warms, or the ATO Sensor running a top-off pump when the level drops).

For sensor control, choose the controlling Probe or Sensor and the condition at which the device switches on or off, and set a fallback state (ON or OFF) for the port to revert to if that Probe or Sensor is ever lost. You can also set a small margin so the device doesn’t switch on and off repeatedly around the threshold. (For the ATO Sensor there’s nothing to set: the pump runs when the water level is low and stops once it is restored.)

Operating a port manually

• In the app, a Start/Stop control lets you run or stop the connected device on demand for a short time, without changing its settings.
• The Manual Control button on the controller runs the assigned port’s device for as long as you hold it (when that port isn’t already switched on) – handy for a quick test or manual top-up. On the Pro, you choose which port (Port 1 or Port 2) the button controls.

The ReefControl ATO Module

The ReefControl ATO Module connects directly to ReefControl Pro/Lite to add a fully featured auto top-off, with a matched pump, tubing and a siphon breaker. Its setup and operation are covered in the ReefControl ATO Module manual.

Using the ATO Sensor for top-off

You don’t need the full ATO Module to automate top-off: the ReefSense ATO Sensor can be added on its own and used to run a top-off pump from a 12 VDC port, or an AC socket on a paired ReefControl Power. It also reports temperature from its built-in Temperature Sensor. Setup, placement and the DIY safety guidance are covered in the ReefSense ATO Sensor manual.

The Leak Detector

The ReefSense Leak Detector reliably detects spilled water – anything from RO water to saltwater – giving early warning of a leak. It connects to the ReefSense port like any other ReefSense Sensor, and you can add several for wider coverage. Placement, the audible alarm and Emergency shutdown are covered in the ReefSense Leak Detector manual.

Probe logs

Every Probe and Sensor records its readings so you can monitor your aquarium over time. In the app you can see the current value, view an interactive graph, and review a log of the daily minimum, maximum and average readings for the last 30 days – handy for spotting trends and gradual changes. For a dual-parameter Probe, each parameter (for example pH and temperature) has its own graph and log.

• Manual reading – take an on-demand reading from a Probe at any time.
• Disable Probe – temporarily pause logging for a Probe so it doesn’t record irrelevant readings – for example while the Probe is out of the water for cleaning. Turn it back on when the Probe is back in service.

Notifications and audible alarm

ReefControl Pro/Lite keeps you informed in two ways: notifications on your phone, and an optional audible alarm on the controller.

Notifications. For each parameter, you can choose to be notified when a reading moves into its Danger range. ReefControl Pro/Lite also notifies you when something needs your attention – such as a leak, a top-off problem or a device that isn’t working as expected. If the controller has a permanent internet connection, you’ll also be notified if it loses its connection to the ReefBeat cloud, for example after a power cut, an internet outage or a router problem. Choose how you’d like to receive notifications under Homepage > Notifications > Settings.

Audible alarm. Each Probe or Sensor has its own audible alarm, off by default. When you switch it on, the audible alarm is enabled whenever that parameter is outside its Acceptable range, and clears automatically once the reading returns to normal. A short press of the Manual Control button silences it. (The Leak Detector, if fitted, has its own alarm with a distinct sound.)

Controlling AC equipment via ReefControl Power

To control mains-powered (AC) equipment such as heaters, chillers, ozonizers and return pumps, pair a ReefControl Power smart power center with your controller. Once paired, any ReefSense Probe or Sensor connected to the controller can switch ReefControl Power’s sockets.

Pairing ReefControl Power

1. Set up the ReefControl Power in the ReefBeat App (see the ReefControl Power manual).
2. Connect it to the ReefControl Power pairing port on the controller, using the cable supplied with ReefControl Power and closing the securing nut fully.
3. Confirm the pairing in the app. The controller’s ReefControl Power Status LED then turns solid.

Controlling the sockets

In the app, open the ReefControl Power and choose which Probe or Sensor controls each socket. Only Probes & Sensors that have been set up and are connected to the controller are available. As with the onboard ports, each socket can be set to Always ON, Always OFF, a Schedule, or controlled by a Probe or Sensor, and one Probe or Sensor can control any number of sockets. For example, a Temperature Probe can switch a heater off and a chiller on if the water gets too warm, or the ATO Sensor can run a top-off pump plugged into a socket.

Reachable from the ReefBeat homepage; lists all Red Sea connected devices on each aquarium, by type and in the order added. Tapping a device opens its actions; the 3-dot menu for a device type acts on all devices of that type at once.

• Turn OFF / Turn ON – temporarily disable or enable a device without unplugging it or losing its settings (Device Manager > device line menu, or the device-type menu for all at once).
• Rename – change the device’s name.
• Delete a device – remove it from the aquarium (Device Manager > device line menu > Delete). Deleting a device before switching it off prevents unnecessary “disconnected” notifications.
• Firmware update – from time to time you may be notified that a new firmware version is available; keeping the device updated ensures compatibility with the ReefBeat App. Update one device via Device Manager > device line menu > Firmware Update, or all devices of a type via the device-type menu. Do not unplug the device while it is downloading and installing. Your previous settings are kept. If an update is not successful, the device automatically reverts to the previous version – repeat the process a few minutes later.
• Reboot – restart the device; your settings are not affected.
• Hard reset (factory reset) – permanently remove all your settings and return the device to its default state. If connected: Device Manager > Hard-Reset. If not connected: hold the Settings button about 15 seconds (until the Wi-Fi LED double-blinks), release, and wait about a minute for the reboot.
• About – shows the device’s details and its current firmware version.
