1.1 System Features
New SET FREE FSR Ceiling Type Indoor Units
HITACHI proudly introduces the New SET FREE FSR Ceiling Type Indoor Units, the highly-ecient and
reliable air conditioning system. Recently, an increasing number of buildings are requiring "Intelligent"
facilities - communication networks, oce automation, as well as a comfortable environment. Particularly,
a comfortable space is required all the day through the year in oce buildings. This multi-split system air
conditioner, SET FREE can meet these requirements. The proven combination of the scroll compressor and
the inverter provides the best air conditioning for small/medium oce buildings.
FEATURES

1.2 Appearance
1.3 Features on Indoor Units
The wired controller “PC-ARF1” must be used for this ceiling type indoor units.
NOTICE
The details are described as follows.
Characteristic Outline
Improvement of Energy Saving
(1) The energy saving has been achieved with the
combination of current outdoor units.
(2) The energy saving is improved by the optional
motion sensor.
• High eciency has been achieved by adopted fan
runner and fan motor and the performance of heat
exchanger has also been improved.
• The motion sensor function controls the setting
temperature, air ow volume and air ow direction,
according to the extent of human activity.
High Eciency and Low Noise by Adopting Fan
Runner
With fan runner with L-shaped ns, the air ow between
ns has been improved and low noise has been
achieved.
Louver Design • Large-sized amenity auto louver softens the discomfort
by temperature irregularity and cold draft.
• The auto louver as a shutter during the operation
stoppage improves design.
Flexibility of Installation to High Ceiling The air ow volume “HIGH 2” has been added, which is
larger than “HIGH”.
Added Optional Receiver Kit • The air ow volume “HIGH 2” can be selected with the
wireless controller.
• By using the wired controller, the unit can be connected
to the motion sensor kit.

zImprovement of Energy Saving
(1) The energy saving has been achieved with the combination of current outdoor units.
(2) Improvement of Energy Saving Operation by Motion Sensor
* Adoption of Motion Sensor Function
- The motion sensor function controls the setting
temperature, air ow volume and air ow direction
according to the extent of human activity.
- The energy saving has also been improved by
combining the motion sensor function and the
individual operating function, compared with the
standard operation.
zHigh Efficiency and Low Noise by Adopting Fan Runner
Developed fan runner has been adopted. By improving shapes of fin and air outlet, the fan efficiency
and the low noise have been improved.

zAdoption of Amenity Auto Louver
Large-sized amenity auto louver with the
same color as indoor unit body has been
adopted. It softens the discomfort by
temperature irregularity and cold draft.
The auto louver as a shutter during the
operation stoppage improves design.

zAdoption of Optional Receiver Kit (PC-ALHP1)
Using Receiver Kit PC-ALHP1 with wireless controller PC-AWR makes wireless remote control possible.
Receiver Kit PC-ALHP1 can uses “HIGH 2.”
NOTES:
1. When using the Receiver Kit PC-ALHP1 with wired controller PC-ARF1, set PC-ARF1 as the main
wired controller.
2. When using the Receiver Kit PC-ALHP1 with Motion Sensor Kit SOR-NEP, the setting from wireless
controller PC-AWR is unavailable. Use wired controller PC-ARF1 for the setting.
FEATURES
TCI-20007-rev.1 1-9
The air conditioning capacity is saved automatically depending on a situation and the amount of detected
human activity by adopting the motion sensor on the corner of the lower cover. The energy saving can be
improved more with the individual operating function. In addition, the operation can stop automatically if the
absent situation continues for more than 30 minutes*1). The motion sensor keeps the indoor environment
more comfortable and reduces unnecessary operations*2).
*1): The default setting is “30 minutes”. However, the setting is changeable.
*2): The default setting is “Running Operation”. However, “Automatic Stop” can be selected by setting
from the wired controller.

stretches on a chair, etc. The detecting
diameter can change to approximately 6.0m.
NOTICE: Motion Sensor
1. The motion sensor detects human activity. However, if someone is in a room with a bit motion, the
motion sensor may detect the absence of human.
2. The motion sensor may detect human activity, if the indoor unit with the motion sensor is installed near
a moving object having dierent temperature from ambient atmosphere.
3. The motion sensor may detect the absence of human even if someone is in a room, when the indoor
unit with the motion sensor is installed on a high ceiling (higher than 4m).
The outdoor unit connectable to the motion sensor kit is limited. Refer to the table “Corresponding
Outdoor Units for Motion Sensor Function” in the item 6 for the corresponding models.
In the case that the three (3)
indoor units individually
installed to each room are
connected to one (1) outdoor
unit and operated.
In a specific room, the air flow volume
and the air flow direction are adjusted
when there is little human activity
for a period of time.
The operation stops automatically
if the activity is not detected for a period
of time. It prevents to forget the turning off
the switch.

The motion sensor may detect the absence of human and the operation may stop in the case of someone
staying for long time with a bit motion.

zSequence of Detection by Motion Sensor
Motion Sensor detects the infrared variation by sensor elements.
Analog voltage is generated according to the infrared variation.
Analog voltage is convert to an digital signal at the threshold.
zSequence of Controlling Motion Sensor at Indoor Unit
The Indoor unit detects whether someone is present or not according to the condition of the digital
signal.
The Indoor unit measures the frequency of detected human activity for a period of time.
The Indoor unit determines the extent of human activity depending on the calculated reaction rate
(frequency).
*Reaction Rate (Frequency) = Detected Counts of Human Activity / Measured Counts of Time
The Indoor unit changes to each operating mode depending on the extent of human activity and the
elapsed time.
The Indoor unit controls the operation automatically in each operating mode.
Measure the frequency of detected human activity in the period of time.
