Jandy Aqualink Firmware Rev B12 Message

I have a Jandy Aqualink 8227. The backllight flashes and the top of the screen says "Firmware Rev B12). The pool filter still comes on at the right time, etc. But obviously, I can't control anything from in the house. Suggestions? Maybe a bad RS/RF Interface board? Just put my house on the market, and I don't want to spend a couple of thousand dollars on a new unit if I can fix this issue. Thanks in advance for your help.

    Thanks for all of the feedback, I will follow through on those. Question - could it be the Wireless Outdoor JBox that communicates between the power center and the wireless remote?

SOURCE: On Jandy Aqualink RS display it says 6700 Rev C

If you bypass the 4 wire cable wire as described by 'the californ', and the problem persists, there is a problem with the control boards. Either the PowerCenter board or the RS remote board. We see this failure alot. It is usually due to a a problem in the RS4/6/8 electronics but in some cases it is the PowerCenter. They can be repaired at a fraction the cost of new at You can send the remote unit first since all the pool functions will remain and they can test it for you. If it is ok, you will have to send the PowerCenter.

I have lost control. Hit the reset button inside the box and now it says "firmware rev B12." But the rest of the screen is blank. help!

From the information given it sounds like it needs to be replaced. On the other hand, a more educated guess might be obtained with a call to the Jandy technical support line at 800-822-7933. They should be able to help you figure this issue out. I hope this helps.

Please vote on this answer. Thank you.
