Jandy VS FloPro DIP Switch Configuration Guide
Quick Summary
- The VS FloPro DV/DVS models have only DIP switches 3 and 4. Switches 1-2 are eliminated by the auto-sensing power circuit.
- For all local controllers (SpeedSet, JEP-R, iQPUMP01) and for the first pump on automation, both DIP switches must be OFF.
- Pre-2022 AquaLink RS systems use DIP switches for pump addressing (up to 4 pumps).
- Post-2022 AquaLink RS systems (Firmware Rev W+) use factory serial addresses instead of DIP switches, supporting up to 16 pumps.
Understanding the DIP Switch Layout
Earlier Jandy variable-speed pumps had four DIP switches (1-4). The VS FloPro DV/DVS models simplified this by eliminating switches 1 and 2. The motor now includes an auto-sensing power circuit that automatically determines whether to supply approximately 10V DC to the RS-485 line for powering a local controller, or to suppress this voltage when connected to a Jandy automation system that has its own power supply. This eliminates a common source of installation errors.
The remaining DIP switches 3 and 4 are located inside the low-voltage compartment on the motor. They are used exclusively for pump address assignment on certain automation systems.
DIP Switch Settings by Controller Type
Local Controllers (No Automation)
| Controller | Switch 3 | Switch 4 | Notes |
|---|---|---|---|
| SpeedSet | OFF | OFF | Unless using automation passthrough |
| JEP-R | OFF | OFF | Always OFF for local control |
| iQPUMP01 | OFF | OFF | Always OFF for local control |
Pre-2022 AquaLink RS (Firmware Rev V and Earlier)
AquaLink RS systems manufactured before mid-year 2022 support up to four variable-speed pumps. Each pump is assigned an address (1-4) using DIP switches 3 and 4:
| Pump Address | Switch 3 | Switch 4 |
|---|---|---|
| Pump 1 (Factory Default) | OFF | OFF |
| Pump 2 | ON | OFF |
| Pump 3 | OFF | ON |
| Pump 4 | ON | ON |
These settings apply whether connected directly to the RS-485 connection on the pump or through a SpeedSet controller's automation passthrough wiring on the bottom of the controller.
Post-2022 AquaLink RS (Firmware Rev W and Later)
AquaLink RS systems manufactured after mid-year 2022 support up to sixteen variable-speed pumps using a completely different method. DIP switches 3-4 are not used. Instead, each pump has a factory-assigned serial address printed on a label on the pump motor.
During setup, pumps with their serial addresses will initially appear in the "unassigned pumps" section of the iAquaLink App or other automation setup devices. Use the app or device to complete pump setup and assign each pump to its function.
AquaLink TCX
AquaLink TCX supports a single variable-speed pump only. DIP switches 3-4 must always be in the OFF position. This applies even when connected through a SpeedSet controller's automation passthrough wiring.
Other Jandy Automation Systems
Other Jandy automation systems support up to four variable-speed pumps using DIP switches 3-4 in the same manner as pre-2022 AquaLink RS (see table above).
How to Change DIP Switch Settings
- Turn off all power at the breaker. Wait at least 5 minutes for capacitors to drain.
- Remove the low-voltage access cover on the motor.
- Locate DIP switches 3 and 4 on the circuit board near the RS-485 connector.
- Use a small tool (pen tip, small screwdriver) to slide the switches to the desired position.
- Reinstall the access cover.
- Restore power and verify the controller or automation system detects the pump at the correct address.
Common DIP Switch Mistakes
- Both pumps set to Pump 1: If two pumps on the same RS-485 bus both have switches 3-4 OFF, they will conflict. The controller cannot distinguish between them and neither may work correctly.
- Switches set for automation when using local controller: If you are using a SpeedSet without automation passthrough, both switches must be OFF regardless. Setting them to ON positions for a non-existent automation address will prevent communication.
- Using DIP switches on a post-2022 AquaLink RS: Newer AquaLink RS systems ignore DIP switches entirely and use serial addresses. Setting DIP switches on these systems has no effect but can cause confusion during troubleshooting.
- Forgetting to power cycle after changing switches: After changing DIP switch positions, you must power cycle the motor (breaker off, wait 5 minutes, breaker on) for the new address to take effect.
How to Determine Your AquaLink RS Firmware Version
The critical question is whether your AquaLink RS system is pre-2022 (Rev V or earlier) or post-2022 (Rev W or later). Check the manufacturing date on the AquaLink control panel label. Systems manufactured before mid-year 2022 use DIP switch addressing. Systems manufactured after use serial addresses. When in doubt, consult the AquaLink RS manual or contact Zodiac Technical Support at 800.822.7933.
Frequently Asked Questions
Where are the DIP switches located on the VS FloPro?
DIP switches 3 and 4 are inside the low-voltage compartment on the motor, near the RS-485 connector. You must remove the access cover to reach them. Always disconnect power first.
Why does the VS FloPro only have switches 3 and 4?
The VS FloPro DV/DVS models have an auto-sensing power circuit that replaces the function of switches 1 and 2. The motor automatically detects whether it needs to supply power to a local controller or suppress power for an automation system.
I have a new AquaLink RS and can't find my pump. What do I do?
If your AquaLink RS is post-2022 (Firmware Rev W+), DIP switches are not used. Look for the serial address label on the pump motor. The pump should appear in the iAquaLink app's unassigned pumps section. Assign it from there.
Can I have more than 4 variable-speed pumps on a pre-2022 system?
No. Pre-2022 AquaLink RS systems are limited to 4 variable-speed pumps because there are only 4 possible DIP switch combinations (2 switches, 2 positions each). Upgrade to a post-2022 system to support up to 16 pumps.
