Jandy and Pentair comes over RS-485 are the same? I.e. a pentair device can control a Jandy pump and viceversa?

A newer Jandy RS automation system can talk to Jandy VS pumps and some of the Pentair pumps, specifically the Intelliflow VS and the Intelliflow VSF pumps.
I haven’t heard of a Pentair automation system talking the Jandy RS-485 protocol.
In general you’re better off sticking with one manufactures line of equipment for best compatibility.

Pentair automation cannot control Jandy VS pumps through RS-485..
Jandy Aqualink Installation Manual[6] section 3.2.7 describes how to connect a Pentair Intelliflo pump to the Aqualink. You need an Aqualink board with at least REV O to control VS pumps.
While the Aqualink RS can control an Intelliflo VS pump it cannot control the VF functions of a VSF pump.
At one time Jandy's F/W was made to talk with the IntelliFlo VS. Then Pentair developed a new pump that was both a VS and VF pump, the VSF. Jandy's F/W has never been updated to drive the VF portion of the VSF pump.
Speculation is several years ago the Big Three (Hayward, Jandy and Pentair) decided to share their RS-485 code, so that they could control each others equipment. Not sure why that did not continue, but as time went on, the firmware running all these systems has changed, but the Big Three no longer keep this interchangeabilty in mind when they update their firmware.
This is the main reason that we always recommend the same brand for products that need to "talk" to each other. It just makes things easier for installation and warranty issue.
