If the valves are at the incorrect position, the circulation pump will be damaged.
If it's necessary to check the running status of the pump when unit power on, please do not touch the internal electronic
control box components to avoid electric shock.
Failure diagnosis at first installation
If nothing is displayed on the user interface, it is necessary to check for any of the following abnormalities before diagnosing
possible error codes.
-Disconnection or wiring error (between power supply and unit and between unit and user interface).
-The fuse on the PCB may be broken.
If the user interface shows "E8" or "E0" as an error code, there is a possibility that there is air in the system, or the water
level in the system is less than the required minimum.
If the error code E2 is displayed on the user interface, check the wiring between the user interface and unit.
More error code and failure causes can be found in 13.4 "Error codes".
