[Notes]
(a) 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.
(b) If the total no. of errors exceed six, other errors should be viewed by switching pages through “
Last
”
and “
Next
”
.
(c) 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.
(d) As some functions are available for the unit, therefore error codes for these functions are also unavailable,
like swimming pool heating function.
