①
The real-time error will show on the control. Taking Error 2 in the above figure for example,
when it is recovered, it will disappear and be replaced by Error 3, and other errors follow the
same way.
②
If the total no. of errors exceed six, other errors should be viewed by switching pages through

” .
③
Any one among “
IDU auxiliary heater 1 error
”, “
IDU auxiliary heater 2 error
”, “
Water tank
heater error
” occurs, the control will beep until this error has been cleared.
See the following table for error description.
