Haywards- Spa T-Cell issues

[econnolly310]

last year we had a new omnilogic panel installed. I have an inground pool and above ground spa which are separate bodies of water. The spa t-cell is plugged into the old salt chlorinator which is set to remote controlled and thats wired into the main panel so it can all be controlled from there.

Ever since we had the new panel work in the SWG generator has never worked for the spa. The levels on the app and panel are the same for the pool and spa but only the pool t-cell is producing chlorine. It's almost like it's just reading the pool t-cell.

A local pool company recommended replacing the t-cell (swapped out the t-5 in the spa for a t-3) repogrammed the panel and still nothing.

Ive also replaced the flo switch and checked the settings in the panel to make sure its set to a different chlorinator for the pool and spa.

Also the old salt chlorinator reads 0. Is tbis just because it's set to be in remote controlled position and should be read from the omnilogic?

Any ideas to get the spa t-cell working would be greatly appreciated.

Welcome to TFP.

I would disconnect the spa controller from the OmniLogic and get it generating chlorine for the spa standalone.

Has the been done to confirm the system works?

I have not tried that yet. Does that require alot of rewiring?

Also assuming it does generate properly would it be an issue with the way it's programmed in the omnilogic?

It shouldn’t but I don’t know the way things are wired for you now.

It would point to problems with the Omnilogic working with the remote system.

Ok and am I understanding this correctly. The omnilogic panel is functioning as the salt chlorinator for the pool (since the swc is hooked into that) and the original chloorinator is supposed to generate for the spa but being controlled through the panel?

Show me pictures of your equipment pad and the spa chlorinator panel.

 

[econnolly310]

Attached are pictures of the panel and salt chlorinator. The T cell for the pool is plugged into the panel and the T cell for the spa which is not working is plugged directly into the chlorinator which is then wired to the panel.

Disconnect the 4 wire control cable between the Swimpure and the Omnilogic.

Check if the jumper on the Swimpure board is set to Primary or Secondary?

 

[econnolly310]

Ok I'll try this. Would this just put the salt chlorinator back to operating the cell for the spa directly?

Yes, it should operate off the Swimpure panel.

The REMOTELY CONTROLLED LED should be off and other LEDs should be lit.

 

[econnolly310]

Yes, it should operate off the Swimpure panel.

Is there a setup that allows it to operate off the omnilogic or was this just setup wrong to begin with?

Not sure.

Tell me what setting that jumper is.

Let’s see if the panel and cell work standalone.

Here is what the inside of the swim lure looks like

@OP, to help better you need to be in the same boat as Allen. Please reference the label on your board.
My observation:
1. It's hard to tell from the photo but it looks like the jumper (J7) is ON. Please confirm!
2. To disconnect the communication cable between the SwimpurePlus and the OmniLogic controller, gently unplug one side of the cable labeled "Comms". Do not unscrew the wires from the connector.
3. It looks like the Thermistor is cracked. To verify please perform #4.
4. Move the switch to Auto, sequentially push the diagnostic button and post the numbers here.
Thank you.

This is all very helpful I'll try it out. I did have someone from a local pool company take a look and they said I needed a new pcb board. Does that sound right?

The modem I have is gl-010056-1 rev c and it seems like the replacements that work with the t-5 and t-3 are much more expensive than the ones that work with the t-15 or t-9.

What are the diagnostic readings? The numbers will allow us to determine if the thermistor replacement is all you need to restore your system. You can get somebody to replace and solder the thermistor for you.
And yes, you can have tech replace the PCB if you feel uncomfortable working with it.

The part number you mentioned above is an older version of the GLX-PCB-RITE, probably sw r1.58. The OEM Aquarite mainboard with sw r1.50 and the latest supports T-cell 3, 5, 9 and 15. If replacing the mainboard, get the genuine Hayward GLX-PCB-RITE with the newest software r1.59 for durability. Pre-owned is ok if it is guaranteed to be fully operational. Stay away from the cheap Chinese knockoffs, they do not support Comms control.

Replaced the pcb board and was getting readings at first but still no chlorine generated. I tried to get an instant salt reading from the swimpure and now it's back to reading 0 and I'm getting no other readings at all. (See attached). Any ideas what could be causing this?

 

[C0d3Sp4c3]

What are the diagnostics from the Swimpure panel? Can you post pictures of the replacement board?
Please review Allen's suggestions above in troubleshooting the Swimpure as a stand-alone system.

 

[econnolly310]

Ok I removed the comm from the omnilogic and now I'm getting readings on the main panel.

Also getting an inspect cell light now.

What's the best way to tell if it's actually chlorinating?

 

[ajw22]

If those pictures say you have 27.1 volts and 2.97 amps then the T-3 cell is generating.

Post a complete set of diagnostic readings

Pressing the diagnostic button sequentially will display:

• Default salt display
• Pool temp
• Cell Voltage - When not generating, the voltage is about 30 to 32 volts dc. When generating, the voltage drops about 1 volt per amp of current.
• Cell current
• Desired output (% of the knob)
• Instant salinity
• Product name
• Software revision (r.XX)
• Cell type
