Main error generation causes
●
Electricity charge apportionment errors are mainly generated when the power breaker of a unit is
switched off.
(Because apportionment data is not sent when the power breaker is switched off.)
When the power breaker of only part of the units in a refrigerant system is switched off, outdoor
unit trouble may occur.
Therefore, if there is a unit whose power breaker is switched off, quickly recover the power by
switching on the breaker.
●
This error may also occur when the communication is disrupted due to disconnection of VRF
communication line. Check that the communication line is not disconnected.
●
This error may also occur when the PC running this application goes into sleep or hibernation
mode. Set the PC so that it would not go into such an energy saving mode.
