I have a Hayward system with a Omni hub that controls the VSP and a relay that controls the lights and waterfall valve. The heat pump is a Hayward model #HP31204T Serial # 21132201504026001. The heating function of the heat pump works excellent I am unable to get the chilling/ cooling function to work though. I set the Omni hub to the correct settings and enabled the chilling. It still does not turn on. I have attached the photos of my Omni hub wiring and the heat pump wiring. Am I missing something? Is something not wired correctly ? Do I need another relay to activate the chilling function? I bought the home 6 months again with all the equipment already installed.

Welcome to TFP.
Which wire connects the HP to the OmniHub?
Point out where the wire connects on both ends.

Unfortunately it looks like your OmniHub only has 1 low voltage relay. You need 2 1 for heat 1 for cool.

They spliced into your pressure switch. That only gives you limited functionality. To have a truly automated system you need 2 low voltage relays.
Sorry man I am kinda new to pool equipment so hopefully you can forgive my ignorance. Are you stating that I need a Omni pl or a bigger Omni hub / brainbox that has more control slots ?
The newer heat cools use rs-485 now and have an HUA you could see if there is a connector for it. It looks similar to one for your pump but I doubt it’s there.
Yes you need to upgrade if you don’t have and rs comm connection for a “smart heater” otherwise just do standalone to cool/heat your pool.
Would it be possible to add a low voltage relay to the system? When you say low voltage relay are you referring to the same type of relay that controls my lights, I think it’s a Hayward HLH485RELAY if I am correct .
Ok. I think I get it now. Thank you so much fellas. I am still getting the hang of this pool equipment stuff. I bought this place and they upgraded everything except the power box, they left the old Hayward gold line control box for the breaker function and moved everything else to the Omni system. I am assuming they did that to be more cost effective. I probably should just get the Omni pl box that has the salt plug in on it so the system can run completely how it’s supposed to
I just removed the flow switch connector to get a clearer picture. lol
