Electricity charge apportionment error with the unit address are displayed for the non-communicating
unit.
The generation time and recovery time are recorded in the error history as with the other errors.
●● In the electricity charge apportionment calculation, non-communicating unit is handled as follows:
· Non-communicating indoor unit: Handled the same as an indoor unit whose operation is stopped
by a remote controller
· Non-communicating outdoor unit: When the non-communicating unit is a master unit, since the
minimum data necessary for electricity charge apportionment is not collected, apportionment
calculation of the relevant refrigerant system is not performed. (Charge becomes “0”.) When a
slave unit is the non-communicating unit, calculation is performed as if the slave unit does not
exist.
