Error Codes Indication

If the ON lamp and display 10
are both blinking: This means
that the Ecodan is out of order
and operation has been stopped
(and cannot resume). Take note
of the indicated unit number and
error code, then switch off the
power to the Ecodan and call
your installer.
If only the display 10 is blinking (while the ON lamp remains lit): Operation is continuing, but there may be a problem with the
system. In this case, you should note down the error code and then call your installer for advice.
If you have entered contact number to be called in the event of a problem, push the button J to display it on the screen.
