What to do if Immergas Water Pump is on but does not heat or cool as expected?

If your Immergas Water Pump is running but not heating or cooling properly, there could be several reasons: * The temperature setting might be incorrect. Check the parameters T4HMAX, T4HMIN in heating mode, and T4CMAX, T4CMIN in cool mode, and T4DHWMAX, T4DHWMIN in DHW mode. * The water flow might be too low. Ensure all shut-off valves are correctly positioned, the water filter isn't clogged, there's no air in the system, the water pressure is above 1 bar (when cold), the expansion vessel isn't damaged, and the hydraulic circuit's pressure drops aren't too high for the pump. * The water volume in the system may be insufficient. Ensure it exceeds the minimum required value.
