Sorry missed this question - The jumpers were jumping the common since it is shared and just one wire. Here is the Pentair wiring diagram.
I purchased these 2 items , the wiring you listed above and a breadboard
Just not sure how to connect that to the relay board. Do you happen to have a discord or anything?
Can anyone confirm that this method makes things easier? Then all that’s left is to add a little YAML…
The following is an AI-generated result that confirmed what I understood from reading the above.
==========================================================
This is actually one of the most reliable ways to automate a Pentair pump (such as SuperFlo VS, SuperMax VS, or WhisperFlo VST) without relying on an intermediate controller or complex RS-485 data frames.
By using the 5V Digital Inputs, the pump acts like a simple controller: as soon as it receives a signal on one of its speed wires, it runs at the pre-configured RPM assigned to that input in its menu.
How to wire it without an external power supply
Although the diagram shows an external 5–30V power supply, you don’t actually need one. The pump supplies its own 5V signal via the RED wire.
Here is the most direct wiring setup using 4 dry-contact relays (potential-free):
+-----------------------+
| 4 RELAY MODULE |
| Sonoff 4CH Pro, |
| IPX800, etc.) |
+-----------------------+
|
[ RED WIRE (+5V) ] -------+---> (Connected to the Common "C" terminal of all relays)
|
- Relay 1 Contact ------> [ GREEN WIRE ] : Triggers Speed 1
- Relay 2 Contact ------> [ YELLOW WIRE ] : Triggers Speed 2
- Relay 3 Contact ------> [ ORANGE WIRE ] : Triggers Speed 3
- Relay 4 Contact ------> [ BROWN WIRE ] : Triggers Speed 4 / Quick Clean
Safety Note: Never connect the RED wire (+5V from the pump) to mains voltage or an external power source! It should only pass through your dry contacts to the color-coded input wires. The BLACK wire serves as ground only if you are using an external power source.
Comparison of the two approaches
| Feature | Relay Method (5V Wires) | RS-485 Method (Flo Buster / Modbus) |
|---|---|---|
| Simplicity | Very simple (just standard relay wiring) | Requires a converter or specific module |
| Reliability | Extremely high (no data packet errors) | Can drop connection if there is bus noise |
| Speed Control | Pre-set via the pump display | Dynamically adjustable (to within 1 RPM) |
| Feedback | None (no live RPM/power telemetry) | Full telemetry (live RPM, Wattage, etc.) |
If your goal is simply to trigger low, medium, or high filtration speeds based on solar power, water temperature, or a pool cover state, the 4-relay dry-contact solution is simple, reliable, and virtually foolproof.
