serious injury.
Indicates a hazardous situation that, if not avoided, could result in minor or moderate
injury.
Indicates information considered important, but not hazard-related (for example,
messages relating to property damage).
General Precautions
To reduce the risk of serious injury or death, read these instructions thoroughly
and follow all warnings or cautions included in all manuals that accompanied the
product and are attached to the unit. Refer back to these safety instructions as
needed.
● This system should be installed by personnel certied by Johnson Controls, Inc. Personnel must be qualied
according to local, state and national building and safety codes and regulations. Incorrect installation could
cause leaks, electric shock, re or explosion. In areas where Seismic ‘’Performance requirements are
specied, the appropriate measures should be taken during installation to guard against possible damage
or injury that might occur in an earthquake. If the unit is not installed correctly, injuries may occur due to a
falling unit.
P5417055
1
● Use appropriate Personal Protective Equipment (PPE), such as gloves and protective goggles and, where
appropriate, have a gas mask nearby. Also use electrical protection equipment and tools suited for electrical
operation purposes. Keep a wet cloth and a re extinguisher nearby during brazing. Use care in handling,
rigging, and setting of bulky equipment
.
● When transporting, be careful when picking up, moving and mounting these units. Although the unit may
be packed using plastic straps, do not use them for transporting the unit from one location to another. Do
not stand on or put any material on the unit. Get a partner to help, and bend with your knees when lifting
to reduce strain on your back. Sharp edges or thin aluminum ns on the air conditioner can cut ngers, so
wear protective gloves.
● Do not touch or adjust any safety devices inside the indoor or outdoor units. All safety features,
disengagement, and interlocks must be in place and functioning correctly before the equipment is put into
operation. If these devices are improperly adjusted or tampered with in any way, a serious accident can
occur. Never bypass or jump-out any safety device or switch.
● Before servicing, turn-OFF current at the power source and use accepted lockout and tag out procedures
at all main switches.
● This unit is the pressurized system. Never loosen threaded joints while the system is under pressure and
never open pressurized system parts.
● Johnson Controls will not assume any liability for injuries or damage caused by not following steps outlined
or described in this manual. Unauthorized modications to Johnson Controls products are prohibited as
they…
◦ May create hazards which could result in death, serious injury, equipment damage or property damage;
◦ Will void product warranties;
◦ May invalidate product regulatory certications;
◦ May violate OSHA standards;

Operation
NOTICE
● Do not insert ngers or objects into air inlet/outlet. Injury can result from rotating fan blades or energized
electrical components.
● Do not touch the wired controller with wet hands. Failure of the wired controller or an electrical shock can
result.
● Hair spray, insecticides, lacquers, and other pressurized substances should not be used within 3.3ft (1m)
of any air conditioning unit. They can react with energized electrical components and cause re.
● Do not install the indoor unit anywhere discharge airow can pass directly toward nearby heating
equipment (space heaters). It may interfere with the combustion process in these units.
● When the indoor unit is operating with heating equipment, ventilate a room sufciently. Any leaked
refrigerant gas that happens to come into contact with any heat source can become toxic on contact and
can cause suffocation in the immediate area.
● Shut down at the main power source if the GFCI (Ground Fault Circuit Interrupter) activates frequently.
Contact your distributor or contractor immediately. Failure to act accordingly can result in serious injury
and damage to the unit.
● CAUTION! If you smell anything burning, shut down the unit and turn OFF the power at the main power
source. Contact the re department and your installer or electrical contractor.
● Make sure that a test for leakage of refrigerant gases has been performed. The refrigerant used for this
unit (HFC R410A) is a non-ammable, non-toxic, and odorless gas. However if refrigerant should leak
and make contact with sparks, re will erupt and generate toxic gas. Also, the uorocarbon, which is
heavier than air will cover the oor surface and can cause suffocation.
● If uorocarbon gas should leak, turn OFF all heating equipment and ventilate the room immediately. Mop
down or vacuum oor areas of residual toxic particulate.
● CAUTION! Do not operate indoor units with the electrical box and switch panel open and exposed.
Incidental contact with energized electrical components can prove fatal.
● Air circulation should be optimized to achieve the best distribution pattern and not settled into isolated
pockets that can make people uncomfortable.
P5417055

Repair / Relocation
NOTICE
● When the air conditioner is to be repaired or transported to a new location, contact your distributor or
contractor. If the repair and the installation are not completed, electric shock or re can result.
Others
● Turn OFF all power at the main power source before performing maintenance work. Failure to do so can
result in damage to internal components with severe or fatal electrical shock.
● Insulate all electrical components and connections from exposure to moisture. Failure to do so can result
in an electrical short, or re.
● Do not tamper with or attempt to "repair" electrical wiring or connections. Call your installer or electrical
contractor. Serious or fatal injury can occur.
● Perform all maintenance work on a rm and stable platform to minimize the risk of injury.
● Do not attempt to "clean" indoor unit components with liquid or powdered cleaning agents during
maintenance. Electric shock, sparks, ame, and serious or fatal injury can occur.
● System piping is charged with refrigerant and highly pressurized.
● Hold the air lter and the air inlet grille securely when attaching or removing it. Carelessness can result in
accident or injury.
● When cleaning the lens surface of the motion sensor, do not make unnecessary contact as the lens can
be easily scratched.

P5417055
3. Before Operation
NOTICE
Apply power to the outdoor unit(s) at least 12 hours prior to system operation to allow for preheating
of the compressor oil. Do not start the system immediately without preheating the compressor.
Otherwise, the compressor can be damaged. Check that the outdoor unit is free of ice and snow
cover. If snow covered, remove with hot water at (122°F or 50°C). If hot water temperature is higher
than 122oF (50oC), it can cause damage to plastic parts.
● When the system is restarted after a shutdown longer than approximately three months, it is recommended
that the system be checked by your service contractor.
● Turn OFF at the main switch when the system has been off for a long period of time.
If the main switch is not turned OFF, electricity is consumed, because the oil heater is always energized
during periods of compressor stoppage.

5.8 Motion Sensor
NOTICE
Detecting Area
r
10.5ft
approx. φ28.9ft (8.8m)
5.8.1 Function
The decorative panel (P-AP160NAE1) is equipped with four motion sensors and one radiation sensor.
● Motion Sensor
These sensors can detect human activity by
measuring the level of change in infrared light
emitted by humans or objects.
● Radiation Sensor
These sensors can detect the radiation
temperature of humans or objects by
(3.2m)
2.6ft
(0.8m)
123°
measuring the level of infrared light emitted by
humans or objects.
Function 1 Automatic Capacity Save Operation
This function can automatically perform the capacity save operation by a human activity in the air-
conditioned area. If there is insufcient or absence of human activity in the air-conditioned area, the motion
sensors detect it and save the air conditioning capacity. In addition, after the motion sensors detect absence
for the period, the operation mode is changed to “If absent”.
● During Capacity Save Operation
* Setting Temperature: The temperature is adjusted 2
o
or 3oF (1o or 2oC) for saving capacity.
* Airow Volume: The airow volume is lowered to one step or to “Slow”.
(except during “dry” operation).
* Airow Direction: The louver angle of controlling airow direction is adjusted horizontally or
downward depending on the operation conditions.
● If absent
The unit performs the operation set by the controller. Refer to Section 5.8.2, “Descriptions for Setting
Items”.
Area of Motion Sensors
(Divided into four areas
among each air outlet)
Area of Radiation Senso
P5417055
● Do not use the motion sensor function in situations where there is a disabled person or an infant. The
motion sensor may detect little motion for a long time as absence, and the operation may be stopped.
● The motion sensor detects human activity. If someone is in a room with little motion, the motion sensor may
detect an absence.
● The motion sensor may detect as human activity if the indoor unit with the motion sensor is installed near a
moving object (ex. swing operation of the heating equipment) which creates a difference in temperature in
the room.
● The indoor unit operation can be stopped by the motion sensor control.
NOTE:
Indoor units with and without motion sensors can be integrated together into a system installation.
In this case, when the operation is stopped by the motion sensor control, the indoor unit without the motion
sensor also stops the operation.
When the total heat exchanger is interlocked with the indoor unit motion sensor, the total heat exchanger
can be stopped with the indoor unit under the following condition:
* The operation mode of the total heat exchanger is set to A/C + VENTI and “If absent” is set to STOP.
However, the total heat exchanger operation mode is “VENTI”, it cannot be stopped even if the “If Absent”
setting is set to “Stop”. This is so because during the “VENTI” operation of the total heat exchanger, the
indoor unit is not activated (because the motion sensor is not active).
● While air conditioning capacity is saved or operation is stopped by the motion sensor control, “Motion
sensor is activated” is displayed on the LCD.
● If the function: “Prohibiting operation by controller”, is activated from the centralized controller, select the
command: “Running” or “Standby” inside the “If absent” condition at the motion sensor controls setting. If
the command “Stop” is selected, motion sensor control is lost and cannot be performed correctly as follows:
* In the case that “If absent: Stop” of motion sensor setting is set by the controller and “Prohibiting
operation by controller” (for all items) is set by the centralized controller, the operation can not be
stopped even if in the indoor unit operation stoppage condition of “If absent: Stop”.
* In the case that “If absent: Stop” of motion sensor setting is set and “Prohibiting operation by controller”
(for part of items) is set by the centralized controller, the indoor unit operation is stopped by the motion
sensor control. However, the indoor unit operation cannot be restarted from the centralized controller.

● If human activity and movements of a heat source are small, the motion sensor cannnot detect them.
● If room temperature is high and there is little difference between the radiation temperature of walls, oor
space, and humans, the motion sensor may not detect increase or decrease in the number of humans.
(For example: The cooling operation is performed with a setting at 86°F (30°C) in the summer season.)
● During the “Capacity Save” and “If absent” phase of operation of Function 1, the Function 2 is unavailable.
5.8.2 Descriptions for Setting Items
● Motion Sensor Setting
The operation mode for activations of functions 1 and 2 can be selected as follows:
* “ALL MODES” : Functions 1 and 2 are available when the operation mode is “COOL”, “DRY”,
“HEAT”, or “FAN”.
* “COOL + DRY” : Functions 1 and 2 are available when the operation mode is “COOL”, “DRY”,
or “FAN”.
* “HEAT” : Functions 1 and 2 are available when the operation mode is “HEAT”.
* “OFF” : Functions 1 and 2 are not available.
(The default setting is “ALL MODES”.)
● If absent
The operation mode for activations during the automatic capacity save operation for Function 1 can
be selected from “Running”, “Stand-by”, or “Stop” on the wired controller. It is set for the indoor unit
operation after the motion sensor detects as an absence for the set time in “Check Interval”.
* Running:
The operation continues with saving the capacity after being detected as an absence.
If human activity is detected over a period of time, normal operation is performed again.
* Stand-by:
The operation mode is the fan operating at “Slow” speed. If human activity is detected for a period of
time, normal operation is performed again.
* Stop:
The operation is stopped by the wired controller when all the indoor units with motion sensor detect an
absence that is connected with the same wired controller. If human activity is detected for a period of
time by the stoppage, normal operation is performed again.
● Check Interval
When the motion sensor detects an absence at a selected check time interval, the function “If absent”
(Function 1) is executed. The interval can be selected from choices ranging from: 30, 60, 90, 120, or
180 minutes.

Enforced Operation:
If all indoor units of a system are Thermo-OFF within approximately
three minutes after the compressor has started, compressor operates
continuously during those three minutes.
However, if all indoor units of a system are stopped by a controller,
compressor is stopped.
When the indoor unit is operating at a low discharge air temperature,
the cooling operation may be changed to a fan operation for a while to
avoid frost formation on the indoor heat exchanger.
It is for self-cleaning the expansion valve when the operation is stopped
at cooling. The sound of the refrigerant ow may be heard from the
indoor unit during the self-cleaning. However, this is not abnormal.
To prevent cold air discharge into a heated space, the fan speed is
changed from the SLOW / LOW setting to a set position based on
discharge air temperature.
At this time, the louver is in a xed horizontal position and “HOT
START” is displayed on the LCD of the wired controller.
The indoor unit fan operation is stopped to prevent cold air discharge
during the defrosting operation. At this time, the message “HOT-START”

This is the sound made when the components
are rubbing up against one another due to the
expansion and contraction of plastic formed parts
brought on by temperature change.
This is the sound made when the refrigerant ows
or the drain-up mechanism drains water. The sound
may be heard especially when starting the operation
or stopping the compressor (for approximately 3
