Installation restriction
z „
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 power consumptions are calculated.
Connect electricity meters to only the necessary air conditioners.
(2) An electricity meter can be connected to VR-II Series air conditioners
An electricity meter can only be installed to the VR-II Series, V-II Series*1, J-II Series.
An electricity meter cannot be connected to S Series and V Series units because they are
not electricity meter supported.
*1: Indoor units and outdoor units with revision code B or later is required.
(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 VR-II Series network converter (UTY-
VGGXZ1), separately connect the electricity meter to VR-II Series VRF air conditioners
because there are some functions *2 that are electricity meter unsupported.
However, UTY-VGGXZ1 which connects a group remote controller is an exception.
*2: [Electricity charge apportionment function]
The electricity charge apportionment function cannot be used with single types air conditioners which are con-
nected 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 per-
formed.

(4) Electricity power meters cannot be nested
Installation of the meters themselves is possible, but use only one electricity meter for the
System Controller . (If both are used, the power consumption will be measured twice.)
