Sorry, I don't know these units. But I had some trouble with a HP control a little while ago. It turned out that I'd been paying too much attention to explaining the system to the work experience kid & forgot to open the valve to the control.
It happens to us all.
So, I'd check that you have power to everything. And that the 3~ rotation is correct. Any fuses are ok. Overloads are ok. Any fan speed / HP controls are correctly set. All valves are in the correct position.
Then press every reset button that you can find.
If that doesn't work, have a cup of tea whilst perusing the manual & any wiring diagrams for clues.
Check Ciat's website and ring the local agent. ;)
Good luck.
Finally, avoid Ciat equipment in the future! Lol
