Pentair IntelliFlo3 VSF 1.5 HP pump with integrated relay board – 011066

Improve your pool’s filtration with the Pentair IntelliFlo3 VSF 1.5 HP variable-speed and variable-flow pump – model 011066.

Designed for modern residential pools, this smart pump combines variable speed, automatic flow control, Wi-Fi and Bluetooth connectivity, and an integrated I/O board that can control up to two compatible auxiliary devices.

The IntelliFlo3 VSF adapts its operation to the pool’s actual needs to ensure stable circulation, effective filtration, and reduced energy consumption.

Variable speed and flow

Unlike a traditional pump that always operates at the same power, the IntelliFlo3 VSF can be programmed according to a specific speed or a specified water flow rate.

This flexibility allows its operation to be adapted to the pool’s various functions:

• Daily filtration
• Water heating
• Salt chlorine production
• Cleaning
• Use of a booster pump
• Operation of compatible water features

The pump can operate more slowly when demand is low and automatically increase its power when a higher flow rate is required.

Sensorless Flow Technology

Sensorless Flow control technology automatically adjusts the motor speed to maintain the programmed flow rate.

It can compensate for changes caused by:

• The gradual clogging of the filter
• Valve movement
• The activation of a pool heater
• The use of a salt chlorinator
• Changes in plumbing resistance
• The activation of other equipment

This regulation helps maintain constant circulation and ensures the proper operation of equipment that depends on a precise water flow rate.

Up to 90% energy savings

The pump adjusts its speed to the pool’s actual needs instead of operating continuously at full power.

According to Pentair, this technology can reduce energy consumption by up to 90% compared with a single-speed pump, depending on installation and usage conditions.

Actual savings vary depending in particular on:

• The daily filtration duration
• The programmed speed
• The pool volume
• The plumbing configuration
• The local cost of electricity
• The connected equipment
• The filtration system’s condition

Extended operation at low speed generally provides effective filtration while significantly reducing power consumption.

Remote control with the Pentair Pool app

Built-in Wi-Fi and Bluetooth connectivity allows you to configure, monitor, and control the pump from the compatible Pentair mobile app.

The app allows you to:

• Start or stop the pump
• Schedule filtration times
• Adjust the speed in revolutions per minute
• Set the flow rate in gallons per minute
• Create different programs
• View operating status
• Receive certain alerts
• Control compatible auxiliary equipment

Feature availability may vary depending on the app version, Wi-Fi network quality, and installation configuration.

Multiple programming modes

The IntelliFlo3 VSF can be configured using different operating modes:

• Manual mode
• Timer
• Scheduled operation
• Set speed operation
• Set flow operation

The pump can save multiple programs to automatically adapt its operation to different times of day.

Integrated I/O board

The model 011066 includes an integrated I/O control board that allows up to two compatible auxiliary devices to be managed directly from the pump.

Depending on the electrical configuration, it can be used to control:

• A pool light
• A salt chlorine generator
• A booster pump
• Certain filtration equipment
• Other compatible accessories

The two outputs have different electrical capacities. The connection must be made in accordance with the limits specified by Pentair and local electrical requirements.

The pump can therefore serve as a simple automation solution for an installation that does not require a complete control system.

Compatible with Pentair automation

The IntelliFlo3 VSF can also be integrated with several compatible Pentair automation systems to centralize pool equipment management.

This integration can facilitate control of:

• Filtration
• Heating
• Lighting
• Salt system
• Water accessories
• Operating schedules

Compatibility must be confirmed based on the installed automation system and its software version.

Optional touchscreen available

A Pentair touchscreen can be added to control the pump directly near the equipment.

This accessory is useful when:

• The phone is unavailable
• The Wi-Fi signal is limited
• Local control is desired
• Multiple people use the equipment

The touchscreen is not included with the pump and must be purchased separately.

Quiet operation

The IntelliFlo3 VSF's high-efficiency motor and hydraulic design enable much quieter operation than a traditional pump when operating at low speed.

This noise reduction is particularly beneficial when the equipment is installed near:

• A patio
• A relaxation area
• A bedroom
• A neighboring residence

The actual noise level depends on the speed, installation, plumbing, and the surface on which the pump is mounted.

1.5-inch and 2-inch fittings

The 1.5 HP model is designed to fit installations using:

• 1.5 inches
• 2 inches

Compatible union fittings facilitate installation in several new or existing systems.

Before purchasing, it is recommended to check the dimensions of the existing plumbing, the available space, and the connection height.

Recommended applications

The Pentair IntelliFlo3 VSF 1.5 HP is particularly suitable for:

• In-ground residential pools
• Installations with a pool heater
• Pools equipped with a salt system
• Systems requiring a constant flow rate
• Projects replacing a single-speed pump
• Installations seeking improved energy efficiency
• Pools requiring simple automation
• Systems using 1.5- or 2-inch plumbing

Sizing must take into account the pool volume, plumbing length, total dynamic head, and installed equipment.

Professional installation recommended

Installing a pool pump requires work on the plumbing and electrical system.

It should be performed by a qualified technician or electrician in accordance with local codes.

Important checks

• Confirm the supply voltage
• Install appropriate electrical protection
• Verify grounding and equipotential bonding
• Properly size the piping
• Check the suction outlets
• Program the speed and flow limits
• Completely prime the pump before starting it
• Check for leaks
• Configure auxiliary equipment correctly

Never run the pump dry. A lack of water can quickly damage the mechanical seal and internal components.
