Why is my Daikin EKHBRD-AY1 Heat Pump not heating properly even when it's on?

If your Daikin Heat Pump isn't heating as expected, even when turned on, there are several things you can check: * Ensure the temperature setting on the controller is correct. * Verify that all shut-off valves in the water circuit are fully open and clean the water filter if needed. * Purge any air from the system. * Check the manometer to confirm sufficient water pressure (greater than 0.3 bar when the water is cold, and significantly greater when hot). * Confirm the expansion vessel is not broken. * Also, ensure the water volume in the installation is above the required minimum. Finally, check if the cooling fans at the rear of the switch box are working properly.
