Features
This unit is a centralized air conditioning management system designed for use with precision air
conditioning systems (PAC, air conditioning systems for ofces and shops, and multi-unit systems for
buildings) and gas heat pump (GHP) air conditioners.
zWith one of these units you can connect and control up to 128 indoor units (2 systems of 64 units each) and 60 outdoor units (2 systems of
30 units each).
zBy connecting a communication adaptor this can be increased to 256 indoor units and 120 outdoor units.
zThe unit is equipped with a 10.4-inch TFT colour touch panel display (1024 x 768 dots), enabling control by almost anyone.
Operation and status P.23
You can check to operational status (ON/OFF, operating
mode, alarms, etc.) of all indoor units and outdoor units in
real time.
You can also select indoor units to change their settings.
Distributing air conditioner
energy P.71
You can view cumulative operating times for indoor units,
engine operating times for outdoor units, and operation
cycles in a list. (Cumulative values)
Using these data, you can calculate the distribution ratio of
electricity or gas consumed for air conditioning and volumes
used (kWh, m3) per indoor unit or in an area, then show
these calculations in a list.
Operation scheduling P.40
You can register daily operation schedules (ON/OFF time,
operating modes, set temperatures, etc.) for individual
indoor units or groups of indoor units.
Operations can be schedule for up to 2 years in advance.
Remote control P.122
The LAN terminal on this unit enables you connect it to a
network.
Connecting to Internet will enable you to operate the unit
and check the status using a PC from a remote location.

The Energy Saving function
Demand control
“Demand” indicates the “electricity demand” (average electricity over 30 minutes).
The basic charges for electricity are determined by the maximum value of
demand (the maximum electricity demand). This maximum demand for electricity
occurs during summer and winter when the air conditioning burden is the
greatest. One way of reducing electric power costs is to suppress the maximum
electricity demand during these periods. (Your actual situation depends on your
contract with your electricity provider)
Furthermore, by suppressing the maximum demand for electricity, you can assist
in the reduction of carbon dioxide emissions and help reduce global warming.
Demand control means that the air conditioning units are monitored so that their
electricity consumption does not exceed a contracted amount, and by setting a level as shown in the following diagram (demand 1, 2, or 3), the
performance of the air conditioning units can be controlled so that energy usage is reduced.
This unit suppress the maximum demand for electricity through automated control of air conditioning units by demand control output (demand
output) signals emitted by external equipments.

Energy navigation function
Indoor units will run in energy saving modes according to the amount of human activity detected by
ECONAVI sensors (sold separately).
Warning
Do not use the ECONAVI feature in rooms where only disabled people or infants are present.
(It may cause damage to their condition or worsen their health)
If there is not much movement for a long time, the ECONAVI sensor may determine that the room is unoccupied and stop the air
conditioning unit.
Note
yYou can turn on or off the ECONAVI feature on this unit.
yYou will need a separate remote controller* with ECONAVI functionality in order to make advanced settings for the ECONAVI feature. Refer to
the operating instructions for the remote controller* with ECONAVI functionality for details on how to congure the feature.
yEven if the target temperature is changed by ECONAVI, the set temperature displayed on the unit will not change.
yEven if the mode is switched to fan due to the absence of people (standby mode), the mode displayed on the unit will not change.
yWhen running multiple indoor units, the energy reduction effect may be reduced depending on the conditions in the room.
* Multi-function wired remote controller (CZ-RTC5 or later)
When there is a lot of human activity

zIn heating mode
The temperature is set lower than when there are people in the
room.
When there are no people for about an hour
yThe units run according to the mode set for when there are no
people. The factory preset is for low energy use operation to
continue with the temperature suppressed. (Refer to the operating
instructions for the ECONAVI sensor for information on the
operation mode when there are no people.)
yIf people are detected while operating in the Absent mode, the air
conditioners return to a mode appropriate to the level of activity.
