Hayward AquaTrol RJ to HP circuit board change out

[C0d3Sp4c3]

The best way to determine whether the cell is energized and producing chlorine is by running the Diagnostics.

For reference, the below photo is the genuine Hayward GLX-PCB-TROL-RJ with the newest software r1.47
Notice the# 147 inside the red box printed on the label at the bottom. Your OEM board should have the Firmware label as well.

Pics of diagnostic s. Al-6. /. R1.47. This is currently working box. I’ll have go go unpack from storage the failed box. But I do remember it as r1.47 and AL-6

Verify if the chlorine production is automatically suspended via the timer.
1. Move the switch to Auto,
2. Manually move the timer switch to the ON position.
3. Wait for the Generating LED to come On.
4. Run the diagnostics and post the numbers.

Cont'd:
5. Manually move the timer switch to the OFF position.
6. Run the Diagnostics and post the numbers.

There is a way to change from AL-7 to AL-6, but I do not know how to do it.

Ask Hayward how to change from AL-7 to AL-6.

From my research. You have to change out the PCB to get AL-7 to AL-6. If…. Only…. Had I purchased correctly and Been mindful to look at contents of box before I went and
Installed. This thread would be unnecessary. BUT, maybe it helps others with knowledge gained on my end. #hindsight. SMH.

It can be done, but it is unlikely that Hayward will tell you how to do it.

It is the exact same board with the exact same software.

The only difference is that one is set to AL-6 and one is programmed for AL-7.

I confirmed that RJ (mine) operates with pump auto function with the analog clock. Set pins for on and off period. Then moved clock to turn on. It shows blinking “no flow” red light for say a minute or so, then “generating” light comes on. Then moved timer and time to off. Pump turns off and
“Generating” light turns off.
So seems to be good for auto. This be RJ. BUT my salt cell is mounted horizontally!! Not vertically which RJ should have since RJ does not utilize flow switch. So, I have a safety issue if… for some reason the water is not flowing, not sure how or what that be. If power or circuit breaker (gfi) is off then pump and SWG is off. Only thing I can think is if the pump looses suction and/or pump fails. Maybe pump cavitates, looses suction.

So I’m going to get the HP PCB for
Safety factor. Which does for say $400 new in Amazon. Cheers

Sell the old ones on ebay.

The RJ model is locked to AL-7. The only way to change that to AL-6 is to re-flash the sw and the EEPROM with data from a HP.

How do you know that there is no way to change the setting?

I am pretty sure that there is a way to do it, but I don't know for sure.

I am not sure if the RJ and HP shares the same software. So far, I have not seen diagnostic readings from a HP user here. They seem scarce and almost non-existent.
Marketing ads for HP's are showing photos of an older RJ board with sw r1.45 like this one.
And this is the closest I can get to identify an HP board.

The AL-7 setting cannot be change in the diagnostics. The only way I've known is to migrate the EEPROM data from a HP board.
The software allows user interaction whereas, the Firmware provides controls for specific hardware. In the case of an RJ, the firmware is locked to AL-7.
OTOH, the AL setting on the AQR bd can be change from AL-0 to AL-5.

 

[JamesW]

I am pretty sure that there is some secret combination of inputs that can change the setting.

However, unless you know the secret method, it is basically useless.

I hear yah. The problem with the RJ bd is that the controller does not know whether the pump is actually running or not.

Make sure you are getting an HP this time. And it would be nice if you can share the diagnostics.

Would a AQR board benefit a user with RJ AL-7 firmware? Any benefits for using AQR board in Aquatrol? Could it still use the analog clock auto pump mode?

When I get and mod. I will make the install known along with diagnostics.

 

[JamesW]

It's the exact same software and the same diagnostic readings.

They both have the same manual and the only difference is the setting.

AL-6 uses the flow switch and AL-7 does not use the flow switch.

Diagnostic Displays
Sequential pushes of the small “diagnostic” button next to the LCD display will cause the AquaTrol to
display the following information:
1. Pool temperature (xx degrees Fahrenheit or Celsius)
2. Cell voltage (typically 22.0 to 26.0 volts when chlorine is being generated, otherwise 30-35V)
3. Cell current (typically 2.50 to 4.00 amps when chlorine is being generated, otherwise 0 amps)
4. Desired Output % (“0P” -- “100P” depending on knob position )
5. Instant salinity ( -xxxx ppm or -x.xx grams/Liter)
6. Product name sent to the display (“AL-6” signifies “AquaTrol” (STD), (“AL-7” signifies “Aqua-
Trol Return-Jet”)
7. Software revision level (r1.xx)
On the 8th push of the button the display will revert back to the default salt display. Also, if the button
is not pushed for 30 seconds, the display will revert back to the standard salt display.

Maybe! I wish I can explore more to help others. But I think that's too much for a pool owner like me. I rest my case!
