Hayward HP31204T Issues

[StinsonAZ]

Moved from here.
Follow up to this post. I have HP31204T and OmniLogic control panel. Are you saying OmniLogic can't control the HP?
When I turn on the HP from App/or control panel, it starts and only runs from 3 seconds and turns off.

Welcome to the forum.
Normally heaters and heat pumps are controlled via something called a Firemans Switch when using automation.

Explain more around the HP turning off after just 3 seconds. Do you have sufficient water flow through it?
