Pentair 522035 Intellicenter Indoor Control Panel Issue

[nsbenz]

I have added an 522035 Intellicenter Indoor Control Panel to my system and I am having a problem with it. For example if I turn on the spa from the main intellicenter control panel I will see the spa is turned on in the 522035 control panel. Now if I turn off the spa from the 522035 control panel it will turn off on the screen, the main intellicenter control panel will not get the change and the spa will not turn be turned off. After a couple of seconds the 522035 control panel will revert back to showing the spa is on. I have updated both control panels firmware to use the save version. Any idea what could be going on?

Thanks.

Is the ICP under warranty?

Remove the ICP from indoors and connect it to the OCP with a short cable and see if it shows the same behavior. If it does then the problem may be with the ICP. If it works then look at the cable.

Change the ICP cable to connect to a different RS-485 connector in the OCP. Don’t double it up with other wires.

Check the connections or replace the 4wire cable between the panels.

No, not under warranty. I will try replacing the cable, what would be the best source for a new cable?

Thanks.

Any 4 wire 22 gauge cable will do.

You can use Cat5 cable and twist each pair together to make it a 4 wire cable.
