•The unit introduces outdoor air and adjusts
the outdoor air temperature via fixed discharge
temperature control, thereby reducing the air
conditioning load.
* The system can operate with outdoor-air temperatures ranging
from -5 to 43°C. Heating performance is somewhat adversely
affected when the outdoor-air temperature is 0°C or below.
* When shipped from the factory, the thermostat is set at 18°C
for cooling and 25°C for heating. The set temperature can be varied
within the range of 13–25°C during cooling operation, and 18–30°C
during heating operation, in the local setting mode using
the wired remote controller. The temperature, however, is not
displayed on the remote controller.
* While in machine protection mode and depending on outdoor air
conditions, discharge air temperature may not be at the set
temperature.
* The fan stops when operating in defrosting, oil returning and hot
start operations. The fan also may stop due to mechanical protection
control.
• Ceiling mounted duct units with three differing
capacities are available. These can be connected
to VRV series outdoor units to meet a variety
of different requirements.

• The "self-diagnosis function" indicates the occur-
rence and nature of abnormalities in the system
by displaying codes on the remote controller.
• Optional equipment includes long-life filters.
• Compatible with outdoor temperatures from -5°C to
43°C.
Notes:
1. The data shown in the graph illustrates the supported operation ranges under
the following conditions.
Indoor and Outdoor Unit
Effective piping length: 7.5 m
Height differential: 0 m
2. The discharge temperature can be set using the remote controller. However,
the actual temperature may not match the temperature setting under some
circumstances due to the outdoor-air processing load or mechanical protection
controls.
3. The system will not operate in fan mode when the outdoor air temperature is
5°C or below.
• High-performance filters with dust collection
efficiencies (JIS calorimetry) of 90% and 65% are
also available as options.
• As with the VRV system,
a variety of control systems
can be deployed, including
remote control from distances
of up to 500 m.
* Group control is not possible between
this unit and standard type indoor units.
Connect remote controllers to each unit.
Navigation remote controller
(Wired remote controller)
(option)
• A central control system
compatible with the VRV
system can be installed.
* It is not possible to change the
discharge air temperature settings
from the central control system.
* Do not associate this equipment
into zones with standard indoor units,
as central control will not be possible.
Central remote controller
(option)
• As with the VRV system, the equipment employs
the "super wiring system" so that the wiring linking
indoor and outdoor units can also be utilised for
central control.

Notes:
*
Linked control of the product and the Heat Reclaim Ventilator is
not supported.
*
This equipment is intended for the treatment of outdoor air only.
It is not to be used for maintaining indoor air temperature. Install
and use with standard indoor units. Be sure to position the air
discharge openings of the product in positions where the airflow
will not blow on people directly. When outdoor-air processing is
in excess, the unit switches to thermo-off mode, and outdoor air
flows into the room directly.
*
For outdoor ducts, be sure to provide heat insulation to prevent
condensation.
*
Group control of the product and the standard indoor units is not
supported. A separate remote controller should be connected to
each individual unit.
*
The system will not operate in fan mode when the outdoor air
temperature is 5°C or below.
*
If the product is allowed to operate 24 hours a day, maintenance
(part replacement, etc.) must be performed periodically.
* Temperature setting and Power Proportional Distribution (PPD)
are not possible even if the intelligent Touch Controller or the
intelligent Touch Manager is installed.
* The remote controller wired to the outdoor-air processing unit
must not be set as the master remote controller. Otherwise,
when set to “Auto,” the operation mode will switch according to
the outdoor air conditions, regardless of the indoor temperature.

Combine fresh air treatment
and air conditioning,
supplied from a single system.
Outdoor-Air Processing Unit
Fresh air treatment and air conditioning
can be achieved with
a single system by using heat pump
technology—without the usual
troublesome air supply and air
discharge balance design. Fan coil
units for air conditioning and
an outdoor-air processing unit can be
connected to the same refrigerant line.
The results are enhanced design
flexibility and a significant reduction in
total system costs.

The following restrictions must be observed in order to maintain the indoor units connected to the same system.
Connection Conditions
• When outdoor-air processing units are connected, the total connection capacity index must be 50% to 100% of the capacity index of the outdoor units.
• When outdoor-air processing units and standard indoor units are connected, the total connection capacity index of the outdoor-air processing units must not exceed 30% of the
capacity index of the outdoor units.
• Outdoor-air processing units can be used without indoor units.
• Connectable outdoor units: VRV and systems.
50 Hz only
For outdoor units of 8 HP and above
Air conditioning and outdoor air processing can be accomplished using a single system.
