When switching on and booting the appliance controller
finds no viable record either in the control module itself
or in the IDM
a) due to overvoltage record in the IDM was
destroyed
b) IDM module defective
c) contact problems of the X10 plug
When switching on and booting the appliance controller
finds no viable record in the IDM.
If there is a viable record in the CM itself, there is an
attempt to transfer this to the IDM. If this works, the error
disappears, if not, the error always appears briefly when
switching on
 fit new IDM
