A pool automation system is one controller that runs the pump, heater, lights, valves and water features on schedules, from a panel at the pad or an app on your phone. Its real value is the schedule. A variable speed pump, a heat pump and a set of color lights each save money or effort only when something tells them when to run and how hard.
We plan automation as one of the custom add-ons on a new build, and we add it to existing pools during equipment upgrades.
What does a pool automation system control?
A pool automation system controls nearly every powered device in the backyard, not only the pump and the water temperature. Jandy lists pool lighting, water features, spa settings, valves, filtration and cleaning systems among what its systems run.
The capacity is larger than most pools need. Jandy's iAquaLink app controls up to 32 pool and spa features, including fire features, light dimmers and landscape lighting. Pentair's IntelliCenter offers 32 feature circuits and 39 auxiliary circuits.
Hayward's OmniLogic ships with 4 high voltage relays and expands to 20 with add-on modules. Each relay switches one device on and off, such as a pool light, yard lights or a water feature pump, so the relay count is the number that tells you how much a system can grow.
Why does automation matter for a variable speed pump?
Automation matters for a variable speed pump because the savings come from running slower for longer, and the controller is what sets those speeds through the day. ENERGY STAR says reducing pump speed by one-half lets the pump use just one-eighth as much energy.
Most replacement pumps are now variable speed by law. Under 10 CFR 431.485, pool pump motors of 1.15 to 5 total horsepower manufactured from September 29, 2025 must be variable speed. Our post on what a variable speed pump actually saves covers the numbers.
Automation then ties a speed to each job. Pentair's IntelliCenter lets you assign a different IntelliFlo pump speed to each feature circuit, so a spillway or the spa jets call for exactly the flow they need. Hayward's OmniLogic controls up to 16 compatible variable speed pumps without using a relay.
How do pool automation schedules work?
Pool automation schedules switch each circuit on and off by time and day, and the better systems adjust those schedules on their own. Pentair's IntelliCenter user's guide allows up to 100 programmable schedules, and a schedule can start at a set time or at an offset from sunrise or sunset.
That sunset option is how lights come on at dusk all year without anyone changing a clock. Jandy's AquaLink RS goes further with what it calls seasonal adjust, which modifies schedules through the year for additional energy savings.
Schedules also save water. The EPA's WaterSense pool guide recommends running water features only while the pool is in use, or putting them on a timer so they shut off after a set time or at night. Automation makes that the default rather than a habit.
What does automation do for the heater?
Automation lets the heater run on a schedule and choose the heat source, which matters most when a pool has more than one. Pentair's IntelliCenter can set the heat mode and temperature inside a schedule, so the spa is warm at the time you planned to use it rather than all afternoon.
IntelliCenter's heat source options include Heat Pump Only, Heat Pump Preferred and Hybrid, which is how a heat pump and a gas heater share the work as the weather changes. Our comparison of a heat pump and a gas pool heater covers which one suits Central Texas.
Controllers also protect the heater. Hayward's installation manual describes a Heater Cooldown setting that lets the heater cool before water circulation stops, and Pentair's system carries a Heater Cool Down delay for the same purpose.
What does pool automation do in a freeze?
Pool automation can start the pump when the air gets cold, so moving water protects the plumbing and equipment without anyone at the pad. Pentair's IntelliFlo manual says that in mild climates with temporary freezing conditions, the filter equipment should run all night.
Pentair's IntelliCenter carries a freeze protection setting on each feature circuit, so a water feature line can be protected along with the main pool. Federal rules allow a pump motor to ship with its own freeze protection disabled, and set its defaults at no greater than 40 degrees air temperature and a run of no more than 1 hour before rechecking.
Does automation work with a pool cover?
Automation works with an automatic pool cover, and some systems change the whole pad's behavior when the cover closes. Hayward's OmniLogic has an Automatic Cover Scale-Back Mode that adjusts pump, chlorinator and heating settings when an electronic cover is closed.
Can you add automation to an existing pool?
Automation can be added to an existing pool, and the scope depends on what is already at the equipment pad. A variable speed pump, valves that can take actuators and lights on their own circuit all make the job simpler.
The smallest step is pump control alone. Jandy describes its iQPUMP01 as entry-level automation that runs a Jandy variable speed pump from a smartphone. A full controller makes sense once you want the lights, heater, spa and features on the same schedule.
If you are already replacing a pump or heater, that is the moment to plan the controller, because the electrician and the plumbing work are at the pad anyway. Trinity Pool Construction installs Pentair and Jandy systems and can tell you which pieces of your current equipment will connect.
What to check before adding automation
- Whether your pump is variable speed, and its brand, since controllers talk most easily to their own maker's pumps.
- How many devices you want to control: pump, heater, pool and spa lights, landscape lights, water features, cleaner.
- Whether the pool and spa share equipment through valves that need actuators.
- Whether you want a heat pump and a gas heater to share the work.
- Where your Wi-Fi reaches, since the app is how most people use the system day to day.
If you want to know what automation would take at your pool, send Trinity Pool Construction a photo of your equipment pad and a list of what you would like to control, and we will tell you what fits.
