Malfunction
If there is a malfunction, the control panel will immediately go to
"Malfunction" mode and display the Malfunction error code.
Due to an internal lag feed in the connected devices, this may
take a few minutes.
If the cause has not been eliminated, the malfunction will occur again
and the control panel will once again go to "Malfunction" mode.
In this case, the malfunction will not be acknowledged on the
control panel and the warning icon will continue to be displayed.
The device will remain in a state of malfunction. Other connected
devices can be operated.
E = Malfunction
