I have the same issue. I’ve tried everything possible to fix the issue. Pentair support showed me to unplug the transceiver, reset, F button, plug the transceiver back when the lights on IntelliTouch scrolling. Remote, menu, setup, advance, 2&4 buttons at the same time. MAN, put in the flashing numbers on the IntelliTouch. Save, exit. Hit reset. Still can’t retrieve data. Power light on the transceiver 520946 is solidHey Rob,
The fact that your mobile touch can see changes made on the outdoor controller makes me think that the mobile touch can receive but not transmit (or that the outdoor transceiver can transmit but not receive). The "can't retrieve data error" leans me toward the outdoor transceiver not being able to receive (but the error could have occurred simply because the button commands couldn't be sent).
The fact that you're getting the "can't retrieve data" error also tells that the buttons are physically functioning (they're on a separate board in the mobile touch 2). When you pressed the button the controller tried to talk to the outdoor unit, so we know the button works.
The comm port is an rs485 bus with each device (mobile touch, indoor controller, pump, is10 spa remote etc) having it's own driver to send/receive. rs485 needs both data lines to send or receive - so the fact that you're getting some communication is a good sign.
Unplugging all other comm port items would just be an additional test... I try to isolate the suspected bad component - which is the mobile touch in your case - so I'd unplug everything except the mobile touch and see if the outdoor controller then responds to mobile touch button presses. The reason for doing this is that another device can load the rs485 bus and disrupt all communication.
**Disconnect power before you unplug any comm port connectors or unscrew any wires from any terminal blocks**
The rf-link is of course separate from the rs485 bus and is the other piece in the puzzle. The mobile touch 2 is still basically a wired indoor controller with a 900mhz transceiver slapped onto it, and either the mobile touch or the outdoor transceiver could be faulty - or experiencing interference from something else. I'm assuming you've tried running these tests with the units in close proximity to each other? Is your transceiver board a 520946, with 3 LEDs... left is rs485, middle is rf link, and power is on the right?
485 and RF flash 6 times then 485 flashes 3 times. The cycle repeat. Do I have a bad transceiver? What should I do? Please help
