Authorized Hayward dealer installed new GLX-PCB-PRO board Rev. 4.46 (previous burned out due to"No Cell Power 2") and is baffled by Check System "Exp. Unit Software PS-16 Comm Error". All features of my set-up work fine except for the error being produced. The alert was never produced with old board. Per ProLogic manual this alert is produced "If an PL-PS-16 and the Expansion Unit is not responding". My unit is a PL-PS-8 and I do not have an expansion unit. Any ideas?

Did "authorized Hayward Dealer" try another board to rule out bad stock?

That's the plan, but not confident that another board (which is backordered) will resolve the problem.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
Go to diagnostics and see if it shows anything for "expansion unit software revision".
Can you post a picture of the board?
Have you tried turning off power for 10 minutes and then back on?
There is a 4 wire connector in the upper left of the board, is there anything connected to it?
Was anything else changed (remote, display etc.)?

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
Nothing in diagnostics regarding "expansion unit software revision".
Have tried the power off and back on for over 10 minutes with no luck.
Nothing changed from previous bad board to present board.
AQL2-BASE-RF is connected to 4 wire connector in upper left of board.
See pictures I already have on hand -- if you need further pictures please let me know.

The green 4 wire Remote Display Communications terminal block in the upper left is where the expansion unit would connect. Turn off power to the system, wait 2 minutes, unplug terminal block and then turn on power to see if the problem goes away.
Since you have an ecostar, I'm assuming that the red wire (#2 on terminal block) goes to the ecostar #7 combus terminal and the black wire (#3 on terminal block) goes to ecostar #8 combus terminal. Is that correct?
Verify correct wiring and then turn off power, reinstall plug and power back on.

Thanks for your help!
Did exactly as you directed regarding the Remote Display Communications terminal block -- error persists. Checked the Ecostar wiring and verified it is correct. Attached is picture of board.

Which display do you have?

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
The original installer of the entire system put in a PS-16 display module in a PL-PS-8 box. I asked about this and was told that's acceptable and would not cause the error, adding that the display board would be blank if that was an issue. Plus this is the same configuration as with the original bad board, which never produced the error.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
I think that's the problem. I think that the display tells the board what system you have. I don't know why it wasn't a problem before. Probably have to contact Hayward for the solution.
You could replace the display. But, there might be a work around.

At over $400 for the PS-8 display module, if it's producing the problem I think I'll just live with the alert. I'll contact Hayward and confirm whether it may be throwing out the alert.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
Hayward thinks a bad board, and confirmed that the PS-16 display module in a PL-PS-8 would not produce the alert. They are monitoring issue with local authorized Hayward installer who is awaiting new board. We'll see...

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
Maybe it's a bad board. However, I still think that it could be the display. If the display tells the board that it's a PS-16, then the board is going to look for communication from the expansion uint.
Maybe the original installer figured out how to tell the board that the expansion unit would not be used. Maybe there's a way to disable aux 7 through 14 and valves 7 through 10. Maybe set them to manual.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
There is no expansion unit installed on my system. However, aux 7 - 14 and valves 7 - 10 always have, and continue to be, set to manual. If next board continues to generate alert I'll request that PS-8 display unit be temporarily installed just to check to see if the PS-16 unit may be causing the alert. Local Hayward installer said they will be enlisting support of Hayward Regional Tech Rep to diagnose problem onsite if they can't resolve. BTW, Hayward said they've had bad programmed boards producing the erroneous alert.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
The difference between a PS-8 and a PS-16 is the display. Since you have a PS-16 display, you have a PS-16 system.
The error makes perfect sense. I don't know why it wouldn't show the error.
The old board didn't do it, so who knows.
Hopefully, the new board will work.
I'm doubtful that there are any boards that just randomly produce the error. If you had the correct display, that would be more plausible. If you Google for that error, you get no results that indicate that it's due to a bad board.
Maybe the reason that the old one didn't do it is there is a way to tell the system to ignore the expansion unit.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
Since the original system was configured as a PS-8, the main board might have been hard set. Maybe the board sets itself when it is first paired with a display.
Since the original display was a PS-8, the main board might have been preset or hard set to that. Maybe that's why the new display did not create any errors.
Since they sell the same main board (GLX-PCB-PRO) for all systems, they have to send them out not preset.
The replacement board figures out which system you have from the display.
I suspect that if they send out a new board it's likely to be preset to PS-8.
What happened to the original display?

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
The board is not defective. It did what it was supposed to do. It's not preset, so it has to figure out what system you have.
The only way that it can do that is to see what display you have. It saw PS-16, so it determined that that's what you have.
If they send a regular replacement board, it's going to do the same thing.
To make it work without the error, they will have to use a board preset as a PS-8.

Re: Guidance Needed: Hayward Check System
That's how the original installer configured my system, a PL-PS-8 board with a PS-16 local display. I did not know at the time much about pools or automation so I just assumed everything was consistent. It was not until the original main board (GLX-PCB-PRO) starting acting up a few years after installation (20 amp fuse blew) that I found out from another warranty service provider about the mismatch.
Note that the exact reading for the error is: "PS-16 Communication Error -- If an PL-PS-16 and the Expansion Unit is not responding." The GLX-PCB-PRO wants to find the expansion unit but can't since I don't have one.
Are there any instructions regarding how would they preset the new GLX-PCB-PRO as a PS-8? Hayward tech support knows about the present configuration of my system.

Re: Guidance Needed: Hayward Check System "Exp. Unit Software PS-16 Comm Error"
I think there is a setting for system type. I don't know if they preset it when they build the system or if the board gets it from the display.
I don't know how to change the setting.
There is software in the display and in the main board.
The answer is going to have to come from Hayward.
I don't think that a new board is going to solve the error unless it can be preset to PS-8.
