Pentair Intelliflo (VSF) Pump Installation

Integrate a Pentair Intelliflo VSF pump with the Clyr Controller, configure it in the Clyr app, and verify successful communication.

Risk of electrocution and shock. Before proceeding with this tutorial, consult a certified electrician if you are uncomfortable working around energized pool equipment because the process involves potentially high voltage.

Tools needed

Stage the tools at the pad so you can complete the wiring in one session.

Clyr Lite or Clyr Controller
Clyr power supply (24VDC)
Pentair Intelliflo automation cable
Small flathead screwdriver
Large Phillips screwdriver
Wire strippers (to shorten the Pentair Intelliflo cable)

Tools laid out for wiring a Pentair Intelliflo VSF pump to the Clyr Controller. — Gather the tools before opening the pump enclosure.

Step 1 - Connect your controller

Make sure the Clyr Controller is powered, online, and associated with the correct pool location before working on the pump wiring.

Follow the controller connection guide if the controller still needs setup.

Step 2 - Plug in Pentair Intelliflo cable

Plug the Pentair automation cable into the VSF pump and run the lead to the Clyr Controller, matching the wiring diagram below.

Wiring diagram showing a Clyr Controller connected to a Pentair Intelliflo VSF pump. — Keep the cable tidy so the conductors reach the controller without strain.

Pentair wires RS-485 differently than other vendors. Land the yellow conductor on the A terminal and the green conductor on the B terminal.

Yellow → RS485A
Green → RS485B

Step 3 - Wiring Clyr Controller

Land the other end of the cable on the RS-485 block, starting with ports A1 and B1 if this is your first device on the controller.

What are networks? Review how Clyr RS-485 networks operate.

Match the colors precisely. Yellow must go to an A terminal and green must go to a B terminal to keep polarity correct.

Pentair Intelliflo cable terminated on a Clyr Controller RS-485 block. — Tighten each terminal firmly so vibration cannot loosen the conductors.

Step 4 - Add pump in app

In the Clyr app go to your location, then open Settings > Devices > Add > Pool Equipment and choose Pump.

Add pool equipment screen in the Clyr app. — Select Pump on the Add equipment screen to begin configuration.

Name the pump, select Pentair Intelliflo VSF pump as the model, and adjust the default RPM or priming time. Enable Main Filter Pump when this is the primary circulation pump.

Pentair Intelliflo VSF configuration options in the Clyr app. — Choose the VSF model so the controller speaks the correct protocol.

Select the network that matches the terminals you used. The default Network 1 corresponds to ports A1 and B1 on the controller.

Selecting the RS-485 network for a Pentair pump inside the Clyr app. — Match the chosen network to the RS-485 port you wired.

Intelliflo VSF pumps default to address 1. When adding multiple pumps to the same network, map the Pentair address to the proper Clyr value:

Pump address 2 → Clyr address 0x61
Pump address 3 → Clyr address 0x62
Pump address 4 → Clyr address 0x63

Advance through the confirmation screens until the final success page appears.

Step 8 - Test the pump

Create a temporary schedule in the Clyr app to verify the pump primes and reaches the desired flow or RPM. You can wait for the controller to acknowledge communication or test immediately.

Review how to build schedules, programs, and autopilot routines if you need help configuring the run.

Next steps

With the VSF pump online you can automate circulation with schedules, programs, or autopilot logic in the Clyr app.

Troubleshooting

The app shows an exclamation mark and reports no communication. Turn the breaker off for 60 seconds and power the pump back up to clear transient faults.
The wiring diagram looks correct but communication still fails. Verify every conductor is on the correct terminal and the schematic above matches your layout.
The wires feel loose inside the terminal block. Tighten each set screw and consider ferrules when landing multiple conductors in one port.
You still cannot communicate with the pump. Reattach the Pentair drive panel or automation interface temporarily to confirm the pump is healthy, then try again with the Clyr Controller.
