Preface
Safety Summary
● Please carefully read this section before installation of the software.
● Contents with "DANGER" shows the certain cases where improper operation WILL result in severe personal
injury or even death. For your safety, please follow this instruction.
● Keep this manual in a safe place for users' reference.
● Contact your distributor or qualied engineer for Installation work. Improper
installation can cause electric shock, re, or unexpected accidents.
● To avoid any electric shock or accident, ask the distributor to have electric work
done by qualied electrician.
Installation and electrical work
● This software applies to normal type of air conditioner and its usage is limited for domestic use only.
● Please do not install this system in following places where installation may cause damage to the adapter.
• Places where oil (including machine oil) mists or stream drift.
• Places where sulde gas form as hot spring drifts.
• Places where ammable gas may be generated or exist.
• Places where high in salt contents surrounding as coast regions.
• Places where atmosphere of acidity and alkalinity humid place.
● In case of using a medical equipment generating electro-magnetic waves, the system should be installed in
an area where free from direct radiation to avoid malfunction.
The surface that is emitting electro-magnetic waves should not directly face the system.
In case of using those equipment and radios generating electro-magnetic waves, this software should
be installed where a location is at least 3 m away from the equipment to avoid any inuence on radiation
propagation in the air.
● The reference pictures printed in this manual are only sample. The display may differ from the actual
window.
[ Symbols Used in This Manual ]
: Immediate hazards which WILL result in severe personal injury or
death.
: Indicates enforcement matters against the general users.
:Indicates prohibited matters.
NOTE: This sign indicates other alert information than DANGER.
NOTICE: Useful information for operation and/or maintenance.

Before Usage
In Operation
● Never operate the equipment with wet hands. It will cause electric
shock.
● Immediately turn the power off if the safety equipments (such as
breaker) frequently turns on, or when safe operation can not be
assured.
Earth leakage or over current can trigger electric shock, re, and/or
blowout. Please contact distributor or your dealer.
● Immediately turn the power off if unordinary condition (burnt smell,
etc) occurs. Operation under unordinary condition can cause re, or/
and electric shock. Please contact distributor or your dealer.
● Do not disconnect the adapter from the computer while
operation. Data in the memory can be broken.
Other Important Notice
● Do not convert or change electric wiring. It can cause serious electric
shock or other unexpected accidents.
● Keep the adapter away from water while cleaning. This adapter is
equipped with electrical parts, which water can cause electric shock.
● Please contact the distributor or your dealer for repair. Faulty/poor
maintenance can cause electric shock and/or re.
● Please contact the distributor or your dealer upon removing the adapter.
Improper installation and removal can cause electric shock, re, or
unexpected accidents.

Before Usage
Important Notice
● Carefully read Installation Manual (P5414794) and Operation Manual (P5414795) before utilizing the
functionality.
● Accurate calculation may not be available upon device failure or other unexpected conditions. Please discuss
the alternative plan (another calculation method independent from the computer and adapter condition) with
your tenant before utilizing the system.
● Operation ratio can not be calculated when the computer and/or the management software is OFF. Ensure the
computer and Management Software are turned ON. Click "Setup incomplete" button in Setting charge section
before operation.
● Save data for operation ratio and calculation result are generated within 30 minutes after date changes. If the
software is shut down during this period, data can not be saved, which the adapter shall generate save data for
the 2 days in a row on the following day.
● Supported calculation method may vary on adapter types. Refer to Setting Charge 4 Register Calc. Mode
of the installation manual (P5414796) for detail.
● This software supports Tooltip (reminder information). It may appear when the mouse cursor is hovered over
items (group name and block name, etc.) on windows (e.g. Tree View). Please note that tooltip may not
appear on all items and/or displays depending on operating state.

• UNITS_yyyymmdd.csv: operation ratio of EHP by each air conditioner (for each day)
• DAYS_GHP_yyyy.mm.csv: operation ratio of GHP by each day
• UNITS_GHP_yyyymmdd.csv: operation ratio of GHP by each air conditioner (for each day)
* yyyy, mm and dd indicate year, month and day, respectively.
(2) The following data (calculation result) will be stored in "centralstation/anbun/DriveRatio/Result/yyyymm/dd".
• HOURS_yyyymmdd.csv: operation ratio of EHP by each hour
• UNITS_yyyymmdd_hh.csv: operation ratio of EHP by each air conditioner (for each hour)
