If your Daikin Air Conditioner isn't heating or cooling as expected, even when turned on, several factors related to water flow and settings could be the cause. First, ensure the temperature setting on the controller is correct. Then, check that all shut-off valves in the water circuit are fully open and that the water filter is clean. Also, make sure there's no air in the system by purging any trapped air. Confirm sufficient water pressure using the manometer; it should be >0.3 bar when the water is cold and >>0.3 bar when hot. Verify the pump speed is set to the highest setting (III) and that the expansion vessel isn't broken. Additionally, ensure the water volume in the installation is above the minimum required value and that the resistance in the water circuit isn't too high for the p...
