My Hayward Aqualogic P8 main board has gone out. When I try to use it, it is turning the filter pump on and off every 2-3 mins and I get an "communications error 2". I ordered and received the Main board part (GLX-PCB-MAIN) and am waiting for my pool tech to install it. The filter has been off for the last 4 days and I want to avoid having to spend gobs of money on chemicals to fix the water (should I have to wait 4-7 days until I can get an appt with him).

Is there a way to by pass the Hayward system and manually turn on my VS pump and run the filter? Should I unplug the system connect at the VS pump? Help please!

Thanks in advance!
 
Your problem is you need to chlorinate your pool.

Your Hayward SWG cell will not run without the board operational. Running the VS pump will not get the SWG running.

Pour 5ppm, a gallon of 10% liquid chlorine, in the pool daily and stir it with your pool brush.

Your water should stay good if you have not yet got algae growing in it.
 
You have an IntelliFlo pump, so it is not going to communicate with your AquaLogic.

What is the pump type in the Configuration menu?

Does the pump get continuous power or does it get power from the Filter relay?

Need help programming equipment

Hi Folks, I just can't figure out how to program my pool equipment. It is getting worse each week, I don't think it should be this hard. My story.....When I first bought my house I did my best to learn how to maintain the pool and program the equipment. 2 years later I had to deal with Breast...

I have a Hayward Intellicomm plugged into my Hayward Aqualogic automation system. It allows the auto system to program and talk to the Pentair VS pump. Not sure how the pump get power.

Oh DUH! I didn't even think about the SWG cell and chlorine. I will do a water reading and add chlorine and acid as needed, then stir the water up with my brush. I was thinking I could use the filter pump to 'stir the water'. I was just worried that algae would grow with the water not moving.
 
It is the chlorine that prevents algae, not the water moving.
 
The Aqualogic does not communicate with the Intelliflo.

The Filter Configuration should not be variable speed pump.

Most likely, it will be two speed pump as we discussed in your previous thread.

Did someone recently change the Configuration menu?

It uses relays to change the pump speed.

That's not communication like if the pump was a Hayward pump.

Go to the Configuration menu and check the Filter Configuration.

We went over the operation in this thread.

Focus on adding liquid chlorine to the pool and getting your system repaired.

Getting the pump running is a distraction.
 
The Aqualogic does not actually communicate with the Intelliflo like it would do with a Hayward pump or like a Pentair Automation System would do with an Intelliflo using a communication cable.

The AquaLogic uses relays to control the Intellicom and the Intellicom communicates with the Intelliflo.

The Aqualogic should not be looking for communication with the pump.

If it is, then the Configuration is probably set to Variable speed pump, which is incorrect.
 
‘Comm Error 2’ is usually a misplaced wire in the sensor terminal block, a failing wired remote, a failing local display or a failing main circuit board.

Turn the system’s main power breaker off, leave off for 2 minutes, then turn
back on and check the display.

Unplug the terminal block labeled
‘Remote’ then turn the breaker back
on (with the block still removed).

If the problem disappears when the block is removed the remote wiring is faulty, the block is bad, the remote is failing or the remote is not in the same family as the local display. If problem still persists turn the breaker off again and proceed to step 5C.

Unplug green terminal block that containsall the sensors then turn the breaker backon (with the block still removed).

If the communication error disappears
then check everything wired into the
sensor terminal block. If the problem
still exists proceed to step 5D.

Check the local display wiring harness for continuity.

If the wiring harness does not show continuity through any of the four terminals, replace the wiring harness. If it is good then replace local display. If replacing the display does not correct problem then replace the main board.
 
The pump might be wired through the relay or directly powered by the breaker.

You can power the pump directly from the breaker and disconnect the communication cable to the Intellicom controller.

The Comm error 2 might be a defective remote or local display.

Check the filter configuration.
 
The remote display (4 terminal green block upper left) does not have the communication wires connected.

It just has the power wires for the Intellicom connected.

Check the Filter Configuration.

Try disconnecting the wireless antenna
(To the right of the remote display terminal block).

It is somewhat difficult to follow the wires, but it looks like the pump is powered directly.

If you disconnect the communication cable, you should be able to run the pump from the pump display.

The main board is probably not bad.

I would go through the steps to disconnect the remote display terminal block and then the wireless remote and then the sensor terminal block to see if they are causing the communication error.

First, try shutting off the breaker to the system for 2 minutes and then power back on to see if the error goes away.

  • Last year my aux pump for the sweeper died and had a new one installed.
  • The mother board for the Aqua logic crapped out and had a company put a new one in.

Most likely, you would need a IntelliComm II Interface Adapter if you want to control the pump from the automation.

Even then, you can probably only do two speeds as that is all the system recognizes.

Right now, the board is set to variable speed pump.

That won’t work.

You can set it to single speed to turn on or off power, but that’s not a good solution.

You can set it to a two speed pump and use the relays to control the IntelliFlo through the IntelliComm II interface.

Or, you can just run the pump in standalone mode if that will do what you want.

IntelliComm II Interface Adapter

The IntelliComm II Interface Adapter provides automatic control of IntelliPro and IntelliFlo variable speed and flow pumps with Pentair Compool systems as well as Jandy and Hayward automation controllers.

How many times has the main circuit board been replaced?

I seriously doubt that the main board has failed again.

Does the remote work?

I would suspect that the most likely cause of the error is a bad wireless remote.

Shut off power and unplug the wireless remote from the board.

Wait two minutes and restore power.
