Does anybody have any experience with getting a HeatPro VS Heat and Cool Heat Pump (HP50951T) to work in Cooling mode on an Omni PL system?

My rep didn't activate cooling mode, we didn't think we would need it, but with the temperatures and the pool cover, the pool is turning into a bathtub every day.

I've gone through the settings/config, I click on 'Heat Pump', click on 'Cooling', and it asks if the unit supports cooling, I say Yes to that, then it asks which relay it's connected to. This is likely the issue, however I have tried the 3 relays that are active (2 LV and 1 HV). When I set all of that and the system restarts, I have the option to enable Cooling in the app, and it says that it's cooling, but the heat pump doesn't do anything.

Any ideas?
 
Do you have the HP50951T or HP50952T?

The 2T has cooling and is Omni compatible.

Shoot, you're right. After doing a bit more in depth research, and despite what my Hayward rep said, and despite being listed on the 'Heat and Cool' section of the website, this model (HP50951T) in fact does not support cooling. Lame. :cry:

Thanks for helping me take a closer look!

(If I ever build another pool I'm going to have SO much more knowledge thanks to the fine people on this site/forum. Thank you all!)
