Two Flow Switches Required?

[jordanal]

Hi all,
Last year, I rebuilt my pool pad equipment with a new Hayward VSP pump and a Hayward OmniHub controller and a new Hayward flow switch, in addition to new piping, valves, etc.. This far South, I just cover the pool and run pool pump when below freezing. The flow switch was connected directly to the OmniHub and worked well and gave me peace of mind that the below-freezing protection was working with a confirmed water flow.

This past Spring, I bit-the-bullet and installed a Hayward Aquarite AQR15 SWG and tied it to the OmniHub controller using the recommended Hayward HLAQRPCB daughterboard. I was forced to unconfigure and disconnect the only flow switch from the OmniHub and connect it directly to the SWG; otherwise, the SWG will not work (no flow error). The flow-switch is the final device, plumbed just after the salt-cell, and a few diameters before the return Jandy diverter valve. The SWG, manageable through the OmniHub, and the connected flow-switch, have all worked well this season.

Now that the season has come to end and I'm preparing to cover the pool again sometime soon, it's really starting to bug me that I don't have active flow monitoring capability for the upcoming freezing nights while the controller is operating in freeze-protection mode. There is no more room for an additional flow-switch in the horizontal return-run without significant replumbing - the worst part being, an additional flow switch would require a good straight run of plumbing (15 inches?) before the switch.

I sent an inquiry to Hayward Support and they confirmed the OmniHub controller cannot monitor the state of the flow-switch through the daughterboard and the AQR15. Any ideas how to replicate a second flow-switch for the OmniHub?

Thanks to all,

If I'm understanding correctly now you must use the second flow switch for your SWCG. During the winter when the water is too cold for the salt system to work why can't you unplug the flow switch from your salt System and use it as you use it last year for the freeze protection.

Ha! Now, I did not think of that! It seems completely logical and once I configure the flow-switch back into the OmniHub, I can simply enable or disable it in the menus as needed. THANK YOU!
