Note:
1
、
The 60 minutes time of the accumulated three times within 60 minutes is calculated with natural time;
2
、
The flicker of the fault lamp is related to its corresponding number except that E72 does not flicker.
3
、
After 4 minutes of communication between the wired controller and the unit, it still displays "in
communication, please wait a moment..." The reason may be for multiple units to dial the code set to the
host.
