I have the hayward omni pl and heat pump HP50ha2 and i finally got my chemicals mostly balanced and decided to close the bypass to the heater. I have set up the temps of low 65 and high 104 as the instructions say but when i fire up the heater in the app it will turn on and show the current water temp and run for 30 seconds then shut off. I have tested this at flow rates from 20 gallons per min to 70 gallons a min with the same affect. Is there something I'm missing here?
