System Restrictions; Notes On Using The Apportioned Electricity Billing Function - Mitsubishi Electric AE-200A Instruction Book

2-5. System restrictions

• "Charge" license is required for each AE-200/AE-50/EW-50.
• Combinations of AE-200 and AE-50/EW-50 units are required.
• M-NET of AE-200 for billing function cannot be used.
• Built-in Pulse Input (PI) of AE-200 for billing function cannot be used.
• Electric energy measurement using a PI controller is recommended.
(If AE-50/EW-50 with built-in Pulse Input (PI) is used, pulse input will not be possible when the
AE-50/EW-50 is stopped, during power outages or during software updates. This could result in
discrepancies between the measurements and the actual electric energy used.)
• Ensure that the same software versions are used on AE-200/AE-50/EW-50 units.
• The apportioned electricity billing function (AE-200 Apportion) and apportioned electricity billing function
(TG-2000A Apportion) cannot be used together.
• When the apportioned electricity billing function (AE-200 Apportion) is being used and you intend to use
the TG-2000A integration software, check that the TG-2000A version is 6.60 or later.
• Electric energy pulse input is required for each AE-200 system. You cannot make settings (apportionment
settings) that span multiple AE-200 systems.

2-6. Notes on using the apportioned electricity billing function

• This function is our original electric energy apportionment system that apportions electric energy using
input from electricity meters with a pulse generator function. Rather than directly measuring the electric
energy used by each air conditioner, pulses are input based on the air conditioner usage by determining
the air conditioner operating status from the content of its communication with the indoor and outdoor
units.
To all users (user license agreement)
The information provided here constitutes an agreement between Mitsubishi Electric and the
customer.
If this "apportioned electricity billing function for the AE-200 air conditioning control system" is used,
this agreement assumes that the customer is using the aforementioned system having agreed to the
terms listed below.
• Mitsubishi Electric and its sales companies accept no liability whatsoever for any incidental,
consequential or special damages incurred by the customer, even where the sales company has
received notification of the potential for damages of that kind.
Nor is any liability accepted for any allegations regarding the rights of a third party.
Important
Any individual agreement between the building owner and a tenant regarding the use of this product
should incorporate the parties' agreement to or accord with the fact that "charges for the use of air
conditioning will be collected in the form of apportioned totals based on the operating status of air
conditioners (including temporary measures to deal with faults)".
• This is a system for estimating the operating electric energy used for air conditioning. As such it
cannot be used as a proof of transaction.
Also, amounts metered using electricity meters are also counted using pulse conversion and
cannot be used as a proof of transaction.
• This is not a system (or its equivalent) in which the operating electric energy used by each air conditioner
is directly measured at the location where the electricity is supplied.
• Because this is an apportionment method that uses the operating status of air conditioner indoor units,
even where the operating time for indoor units is the same, the amount of operating electric energy used
may differ depending on the model configuration and operating status of the outdoor units.
(The apportioned electric energy may be different when compared with a situation where an electricity
meter is assigned to each air conditioner.)
• Air conditioners still receive current even when stopped, and electric energy is apportioned to idle air
conditioners as standby electric energy.
• While the amounts of electric energy, water and gas used are obtained through pulse conversion,
