(Example 2) A configuration where the apportioned electricity billing function is required (when the outdoor units
in the same system are installed to multiple tenants)
AE-200
HUB
LAN
AE-50/EW-50
The electric energy used by an air conditioner consists of the electric energy that is consumed by the outdoor
unit and the electric energy that is consumed by the indoor unit. And the outdoor unit electric energy consumption
consists of the operating electric energy plus the standby electric energy. Similarly, the indoor unit electric energy
consumption consists of the operating electric energy plus the standby electric energy.
With the apportioned electricity billing function, the respective amounts of electric energy can be apportioned
based on the operating status and capacity of each tenant.
The example below describes a system where electric energy is metered (with-metering-device method).
(In systems where the electric energy is entered manually (no-metering-device method), standby electric energy
will not be apportioned.)

The apportioned electricity billing function can be implemented either by apportioning in the AE-200 units or
by using the TG-2000A integration software. This manual explains how to use the function by apportioning in
AE-200 units.
If you are using the TG-2000A integrated management software, refer to the TG-2000A Instruction Book.
