• Installation restriction
Install electricity meters in accordance with the following restrictions:
– 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.
– An electricity meter cannot be connected to S series and V series units because they are not
electricity meter supported.
– Electricity meter supported/unsupported units cannot be mixed under 1 electricity meter. (Be-
cause the available functions are different.)
When connecting single type air conditioners via Network convertor (UTY-VGGXZ1), separately
connect the electricity meter to VRF air conditioners because there are some functions that are
electricity meter unsupported such as Electricity charge apportionment function*
2
ing function* . However, UTY-VGGXZ1 which connects a group remote controller is an excep-
tion.
1
* : The electricity charge apportionment function cannot be used with single types air condition-
ers which are connected to a network converter.
2
* : In the peak cut control, though the power will be included in the target power, the actual con-
trol will not be performed.
Whm
– Electricity power meters cannot be nested
Installation of the meters themselves is possible, but use only 1 electricity meter for the System
controller. (If both are used, the power consumption will be measured twice.)
– The externally linked units* shall be connected to the same electricity meter as the air condition-
er to which they are connected.
*: General-purpose unit which performs calculation as an externally linked unit by electricity
charge apportionment function.
