z Installation restriction
„
Install electricity meters in accordance with the following restrictions:
(1) Install an electricity meter only to air conditioners which are the target of the function.
When electric lights and other OA equipment are connected to the electricity meter, also
their Input Powers are calculated.
Connect electricity meters to only the necessary air conditioners.
(2) An electricity meter cannot be connected to S Series and V Series units because they are
not electricity meter supported.
(3) Electricity meter supported/unsupported units cannot be mixed under one electricity meter.
(Because the available functions are different)
When connecting single type air conditioners via network converter (UTY-VGGXZ1),
separately connect the electricity meter to VRF air conditioners because there are some
functions *2 that are electricity meter unsupported.
*2: [Electricity charge apportionment function]
The electricity charge apportionment function cannot be used with single types air conditioners which are
connected to a network converter.
[Energy saving function]
In the peak cut control, though the power will be included in the target power, the actual control will not be
performed.

measured twice.)
