5-2-3. Energy Management
On the Energy Management screen, make the settings for the energy-control-related items that appear on
the screens under the [Energy Mgmt] menu, such as temperature sensor to measure the outdoor temperature
with, electricity meters that are used for acquiring the data to display the trend graph of indoor unit electricity
consumption, and also the mode that are used for apportioning indoor unit electricity consumption.
Touch [Function1] in the menu bar, and then touch [Energy Management].
Note: Electricity consumption is apportioned based on the electricity consumed by outdoor units. The electricity consumed by
indoor units is not considered.
Note: HWHP (CAHV, CRHV, QAHV) units and chiller units do not support this function.
Important
● AI and PI controller settings are required beforehand to make energy management settings. Refer to section 5-2-2
“Measurement” for details.
● The energy management settings must be made after all units have been started up. The settings that have been saved
while one or more units are starting up may be lost.
(1) Touch the “Temperature Sensor” button. The name of the
temperature sensor that is connected to the AI controller or
the AHC will appear.
Select a temperature sensor to measure the outdoor
temperature with, and then touch [OK].
Note: To deselect the selection, select [-- --].
Note: This setting is not required when not showing the outdoor
temperature in a line graph on the [Energy Use Status]
screen.
Note: This setting is interlocked with the temperature sensor
setting on the [External Temperature Interlock] screen.
(2) Touch the [Indoor unit operation apportioning mode] button.
Select the way indoor units’ operation time is counted that is used to apportion the electricity consumption,
which appears on the screens under the [Energy Mgmt] menu.
Select [Fan operation time] to apportion the electricity consumption based on the fan operation time, and select
[Thermo-ON time] to apportion the electricity consumption based on the Thermo-ON time of the indoor units.
Select [Capacity save amount] to apportion the electricity consumption based on the indoor unit operation time
that was calculated based on the amount of energy saved on the indoor units.
The selected setting must meet the system requirements. Selecting [Capacity save amount] is recommended.
