Limitations on changes to settings
There may be limitations on the changes you can make to settings depending on the model of air conditioning unit. For example:
y
You cannot make changes to “Heat” when the unit is a specialised cooling machine
y
With the exception of some models, floor mounted units do not al
low you to change the fan speed from “High”.
y
You will not be able to change the airflow direction on ceiling e
mbedded types if they don’t have flaps
So please use this unit with consideration for the peculiarities of each of the units. Contact the place of purchase or your servicing agent for details.
Standby power (with time distribution)
This unit calculates distribution based on the operating times of the indoor units.
The electricity and gas consumed while stopped (standby
power) is not distributed. For example, if no air conditioners operate for a month, the standby power is not distributed to any distribution group. If an
indoor unit operates
for even a minute, however
, all of the standby power is distributed to the distribution group to which the indoor unit belongs.
With load distribution the standby power is included in the distribution.
The display on the screen when making changes
When you have made changes to the settings for indoor units on this unit, you may see the display returning temporarily (especi
ally when
performing batch operations).
This is just a delay caused by communication and is not indicative of a malfunction.
Air conditioning distribution ratios and air conditioning usage
The methodology adopted on this unit for calculating air condit
ioning distribution ratios and air conditioning usage is only a
simplified one.
There
will be dif
ferences from the usage volumes billed by the electricity and gas providers.
Depending on operating conditions, there will be dif
ferences from the actual air conditioning volumes and the distribution ratios.
Due to the rounding of fractions when calculating distribution ratios, you will observe dif
ferences arising between the following pairs of data.
y
“Distribution rates of areas within a distribution group” and “100.00%”
y
“T
otal of the distribution rate breakdown” and “distribution rate of the entire area”
y
“T
otal of usage in each area” and “total usage according to the pulse meter”
y
“T
otal of usages for in hours, out of hours, and cut-of
f days” and “usage for the whole time”
As this unit calculates distributions (proportional allocation) through a comparison of load estimated for each indoor unit rat
her than measuring
energy directly
, please use the calculations only as a guide.
The current time and date settings
The unit’
s clock is accurate to ±30
seconds per month (at a normal temperature of 25
°C), regularly adjust the time and date against a reliable
source.
About distribution data
If you remove an air conditioning unit after accumulating distribution data, all accumulated values for that air conditioning u
nit are deleted, so it
will not be possible to view distribution data that includes that air conditioning unit after it is removed. Before removing the unit, output (save) the distribution data a
s a CSV file to a USB memory device.
The output method for CSV files is the same as for outputting hi
stories. (→ “Outputting (saving) logs as a CSV file” (P
.60))

Miscellaneous
Indemnity
This company shall not compensate in the following cases.
y
If the password is found out by a third party and problems result
y
If a USB memory device malfunctions and backed up data (accumulated data, distribution data) is lost
Where large errors can occur in calculation
Some models (semi-centralised models, floor mounted models, etc.
) and old models with electric heaters for example, may show la
rge
dif
ferences in calculations of air conditioning distribution ratio
s. Furthermore, if you use large pan type humidifiers that use a
lot of power
, the
operating times of the humidifiers will not be reflected in the c
alculation of the distributions, leading to a large dif
ference.
Contact the place of purchase or your servicing agent for details.
Remote control-less systems
In a system without remote controllers where only one centralised device has been installed, if that device breaks down then yo
u may be faced
with the problem of not being able to run the air conditioning units. It is our recommendation to install multiple centralised
devices for safety
purposes.
The identification number
You should take a note of the identification number and keep it i
n your records.
You should also take care not to reveal the number to a third
party
.
Contact the place of purchase or your servicing agent if you forget the number
.
Screen disruptions
There may be some disruption to the screen when it is refreshing, but this is not indicative of a malfunction.
