12 Supplementary Information-2

 Powering the system off
Always use the following procedure to power the Intelligent Controller off.
Touch the Power off button in the "Other settings" screen (
Touch the OK button in the message box which appears to ask if you want to exit the program.
Wait until a message appears to inform you that "It is now safe to turn off the Intelligent Controller." (∗)
and then power the system off.
(*Several minutes may pass before this message appears.)
 Air conditioner limitations
Some types of air conditioners are limited in the settings which they support.
For example, cooling-only air conditions cannot be set to heating.
Floor-type models typically support only high fan speeds.
Ceiling mounted models do not have fl aps, and therefore cannot change the fan direction.
You should be aware of the limitations of the air conditioner models in your system.
For more information, contact your dealer or service provider.
 Standby power (for simple distribution)
The Intelligent Controller performs distribution calculations on the basis of indoor unit operating time.
Therefore it does not count power consumed while under are stopped (on standby).
For example, if no units are operated over the course of a month, no standby power consumption is
distributed to any tenant. However if a unit is operated for even one minute, then all of the standby
power consumption is distributed to the corresponding tenant.
For loaded distribution, distribution is made with standing-by power added.
 W Multi GHP outdoor unit data is displayed as "Reference unit".
Because the reference unit changes depending on operating conditions, the data displayed by the
Intelligent Controller also changes.
Outdoor unit data is data such as "number of operations" and "operating time".
 Only an alarm code is displayed in the notifi cation bar and alarm log display.
The content of an alarm can very for different models, even if the alarm code is the same. Consult the
documentation of the various models to determine the content of the alarm.
 Because of data transmission delay, the totals and distribution data displayed by the Intelligent Controller
for different time zone (regular hours, out of hours, special days) may not be counted in a completely
accurate fashion.
For details, see "6.6.3 Time zone totals and distribution".
 Filter cleaning signs and oil exchange signs are updated every 7 minutes (maximum).
Operating time totals and distribution data are updated every 18 minutes. Electric heater ON time is
updated once an hour.
 Cut off processing for the previous day is performed every day for a few minutes after 00:00 a.m. The
system will not respond to user input during this processing.
 After the settings of an indoor unit are changed from the Intelligent Controller, the display may revert
temporarily to the former settings. This is more likely to occur with all-unit operations. The cause is
communications delay, not any malfunction in the system. If you wait a few minutes, the display will
show the correct information.
