Quick Answer: How Does Pool Automation Work?

Pool automation uses a central controller to operate compatible pool and spa equipment. The controller follows programmed schedules and user commands, then communicates with pumps, heaters, lights, valves and other connected devices through supported electrical or communication interfaces.

Depending on the system, you may be able to control equipment from a local panel, schedule daily operation or use a smartphone app. The available functions depend on the controller, connected equipment and installation configuration.

Pool Automation at a Glance

What Is Pool Automation?

Pool automation is a control system that allows compatible swimming pool and spa equipment to be managed from a centralized controller.

Depending on the system, automation may control:

• Pool pumps.
• Variable-speed pump settings.
• Pool and spa heaters.
• Pool and landscape lighting.
• Water features.
• Valve actuators.
• Pressure-side cleaner pumps.
• Salt chlorine generators.
• Other compatible auxiliary equipment.

For a more comprehensive look at equipment compatibility, scheduling, networking, capacity and system selection, see our Complete Guide to Pool Automation.

What Is the Automation Controller?

The automation controller is the central command center of the system.

It receives user commands and follows programmed schedules, then operates compatible equipment through relays, communication connections, actuators or other supported interfaces.

The controller may also receive information from connected sensors and compatible equipment.

For example, a pool-and-spa controller may use temperature information, pump settings and valve positions to coordinate a requested heating mode.

Example: What Happens When You Activate Spa Mode?

Consider a hypothetical pool-and-spa installation with shared circulation equipment.

When the owner selects spa mode, a compatible automation system may perform the following sequence:

1. Receive the spa-mode command.
2. Move compatible valve actuators into the programmed spa positions.
3. Operate the circulation pump at an appropriate setting.
4. Use the configured spa temperature setting.
5. Request heating when the water temperature and programmed conditions require it.

The exact sequence depends on the plumbing, controller, heater and other installed equipment.

Not every pool-and-spa installation shares circulation equipment or uses the same automation arrangement.

How Does Pool Automation Control Equipment?

The control method depends on the equipment being operated.

Traditional equipment may be switched through approved electrical relays. More advanced equipment can communicate directly with compatible automation systems, allowing more detailed control than simply turning a device on or off.

For example, a compatible variable-speed pump may allow automation to select different operating speeds for filtration, heating and water features.

See Pool Automation and Variable-Speed Pumps for more about coordinating pump speeds, schedules, heating, cleaning and other pool functions.

What Is the Difference Between a Relay and a Feature Circuit?

These terms can describe different parts of an automation system.

A relay is a physical electrical switching component. It can turn an approved connected load on or off.

A feature circuit is a programmable function available on certain controllers. Depending on the platform, it may activate an assigned relay, request a supported pump speed, operate a valve or coordinate another compatible function.

A feature circuit does not necessarily require its own dedicated physical relay.

Example: Operating a Water Feature

Suppose a pool has a water feature supplied by the main variable-speed pump.

A compatible automation controller may use a programmed feature to request the pump speed needed for that water feature.

Another installation might have a separate water-feature pump that requires an appropriately rated relay or another approved control connection.

The correct configuration depends on the equipment and plumbing design.

How Pool Automation Controls Valves

Motorized valve actuators can automatically reposition compatible plumbing valves.

This is particularly useful on pool-and-spa combinations where circulation must be redirected when switching between operating modes.

Valve actuators may also be used for certain water features and other plumbing functions.

Example: Pool Mode vs. Spa Mode

This example illustrates a shared-equipment installation. Actual valve positions and operating requirements depend on the plumbing design.

Incorrect valve programming can interfere with circulation. Valve actuators should be installed and configured according to the equipment manufacturer's instructions.

How Pool Automation Scheduling Works

Scheduling is one of the most useful automation features.

Instead of manually operating equipment every day, owners can create schedules for supported functions such as:

• Pool circulation.
• Variable-speed pump operation.
• Heating.
• Lighting.
• Water features.
• Cleaner operation.
• Compatible sanitation equipment.

Available scheduling options depend on the controller and equipment configuration.

Example: A Daily Pool Automation Schedule

Consider a hypothetical pool with a variable-speed pump, salt chlorine generator, heater and automated lighting.

This is an illustrative schedule, not a recommended operating plan. Actual circulation, sanitation and heating requirements depend on the pool and its equipment.

Can Pool Automation Be Controlled From a Phone?

Many connected automation platforms provide smartphone monitoring and control when the system has the required network connection.

Depending on the manufacturer and installed equipment, an app may allow owners to:

• Turn compatible equipment on or off.
• Change schedules.
• Adjust supported pump settings.
• Adjust pool and spa temperature settings.
• Control compatible lighting.
• Activate water features.
• Check available system-status information.
• Receive supported equipment alerts.

Not every controller or connected device supports every function.

Does Pool Automation Require Wi-Fi?

Pool automation does not necessarily require Wi-Fi for local equipment control.

Many systems can continue operating locally programmed schedules without an active internet connection.

However, remote smartphone access and cloud-connected functions generally require appropriate network connectivity.

Depending on the system, networking may use Wi-Fi, Ethernet or a separate manufacturer-supported interface.

If you are comparing network-connected pool-control options, verify the exact controller and networking requirements.

If local controls work but remote access does not, see Pool Automation Not Connecting to Wi-Fi for a troubleshooting sequence.

Can Automation Save Energy?

Automation does not automatically make every piece of equipment more efficient.

Its advantage is that it can make equipment operation more consistent and easier to schedule.

For example, a compatible variable-speed pump can use different settings for filtration, heating, cleaning or water features rather than operating at one unnecessarily high speed for every task.

Example: Comparing Two Pump Operating Modes

Consider a hypothetical variable-speed pump with the following measured electrical consumption:

At an illustrative electricity rate of $0.18 per kWh, the lower-speed mode would cost approximately $0.58 for eight hours, compared with $2.16 for the higher-speed mode.

However, these operating modes may circulate different amounts of water. A lower-speed schedule must still satisfy the pool's circulation and connected-equipment requirements.

The figures are hypothetical and do not represent a particular pump model.

Can Pool Automation Control a Heater?

Compatible systems can manage pool and spa heating functions, including supported temperature settings and schedules.

The controller may coordinate heating requests with pump operation, temperature sensors and other compatible equipment.

See Pool Automation and Pool Heaters for more about coordinating temperature settings, circulation, heating schedules and pool-spa operation.

Can Pool Automation Control Salt Systems?

Some automation systems integrate with compatible salt chlorine generators and other sanitation equipment.

Depending on the equipment, integration may provide access to supported operating settings, status information or coordinated schedules.

Salt chlorine generators require adequate water flow and must retain their required safety protections.

Automation should not be used to bypass flow sensing or other manufacturer-required safety features.

Can Pool Automation Control Lights?

Yes. Compatible pool and spa lights can be incorporated into automation systems.

Basic control may provide switching and scheduling, while supported color-changing lights may offer additional lighting programs and group-control functions.

See Pool Automation and Pool Lights for more about schedules, remote lighting control, color features and compatibility.

Can Pool Automation Control Water Features and Cleaners?

Some automation systems can operate compatible water features, dedicated pumps and cleaning equipment.

For example, a water feature may require a programmed variable-speed pump setting or a separate equipment circuit.

A pressure-side cleaner with a booster pump may require coordinated operation with the main circulation system.

The supported functions depend on the controller, equipment and plumbing configuration.

What Happens When Multiple Equipment Functions Run Together?

Several pool functions may operate at the same time.

For example, a filtration schedule may request one pump speed while a heater or water feature requires additional flow.

Compatible automation systems use their programmed operating rules to coordinate these requests.

Before commissioning the system, verify that simultaneous operation provides the required flow and does not exceed the limits of connected equipment.

Do not assume every controller handles overlapping schedules or equipment priorities in the same way.

Is Pool Automation Worth It?

The usefulness of automation depends on how much equipment you want to coordinate and which functions you want to control centrally.

A simple pool with one circulation pump may have relatively straightforward scheduling needs.

A pool-and-spa combination with variable-speed pumps, heating, lighting, water features, valves and sanitation equipment may require more extensive coordination.

What Should You Consider Before Choosing a System?

• Existing equipment compatibility.
• Number of equipment circuits required.
• Pool-only versus pool-and-spa operation.
• Number of valves requiring automation.
• Supported pump-control functions.
• Heater and sanitation compatibility.
• Lighting and water-feature requirements.
• Remote-access requirements.
• Future equipment additions.
• Available expansion capacity.
• Professional installation requirements.

Before purchasing an automation system, verify that the controller supports the specific pumps, heaters, lights, sanitation equipment and other devices you intend to connect.
