SAFETY MESSAGES
Indicates a hazardous situation that, if not
avoided, could result in death or 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 (e.g. 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 this product and the indoor and
outdoor units.
This system, including this controller, should be installed by personnel
certified by Johnson Controls, Inc. Personnel must be qualified
according to local, state and national building and safety codes and
regulations. Incorrect installation could cause leaks, electric shock, fire
or explosion.
Use appropriate personal protective equipment, such as gloves and
protective goggles and electrical protection equipment and tools suited
for electrical operation purposes.
Do not stand on or put any material on the controller.
When installing the controller cabling to the units, 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.
Use only Johnson Controls recommended or provided as standardized
or replacement parts.
Johnson Controls shall not assume any liability for injuries or damage
caused by not following steps outlined or described in this manual.
Unauthorized modifications to Johnson Controls products are
prohibited as they…
-may create hazards which could result in death, serious injury or
equipment damage.
-will void product warranties.
-may invalidate product regulatory certifications.
-may violate OSHA standards.
i

Take the following precautions to reduce the risk
of property damage
Do not touch the main circuit board or electronic components in the
controller or remote devices. Also, make sure that dust and/or steam
does not accumulate on the circuit board.
Locate the wireless zone controller at a distance of at least 3 ft.
(approx. 1m) between the indoor unit and electric lighting. Otherwise,
the receiver part of the unit may have difficulty receiving operation
commands.
If the wired zone controller is installed in a location where
electromagnetic radiation is generated, make sure that the wired zone
controller is shielded and cables are sleeved inside conduit tubing.
If there is a source of electrical interference near the power source,
install noise suppression equipment (filter).
During the run test, check the unit’s operation temperature. If the unit is
used in an environment where the temperature exceeds the operation
boundary, it may cause severe damage. Check the operational
temperature boundary in the manual. If there is no specified
temperature, use the unit within the operational temperature boundary
of 35°~104°F (0~40°C).
Read installation and appropriate user manuals for connection with PC
or peripheral devices. If a warning window appears on PC, the product
stops, does not work properly or works intermittently, immediately stop
using the equipment.
INSTALLATION PRECAUTIONS
To reduce the risk of serious injury or death, the
following installation precautions must be
followed:
If the remote sensors are not used with this controller then do not
install this controller…
-in a room where there is no thermostat.
-where the unit is exposed to direct sunshine.
-where the unit will be in close proximity to a heat source.
-where hot/cold air from the outdoors, or a draft from elsewhere
(such as air vents, diffusers or grilles) can affect air circulation.
-in areas with poor air circulation and ventilation.
Perform the run test using the controller to ensure normal operation.
Safety guards, shields, barriers, covers, and protective devices must
be in place while the compressor/unit is operating. During the run test,
keep fingers and clothing away from any moving parts.
ii

After installation work for the system has been completed, explain the
“Safety Precautions,” use, and maintenance of the unit to the customer
according to the information in all manuals that accompanied the system.
All manuals and warranty information must be given to the user or left
near the Indoor Unit.
ELECTRICAL PRECAUTIONS
Take the following precautions to reduce the risk
of electric shock, fire or explosion resulting in
serious injury or death:
Only use electrical protection equipment and tools suited for this
installation.
Insulate the wired zone controller against moisture and temperature
extremes.
Use specified cables between units and controller.
The polarity of the input terminals is important, so be sure to match the
polarity when using contacts that have polarity.
Highly dangerous electrical voltages may be used in this system.
Carefully refer to the wiring diagram and these instructions when
wiring. Improper connections and inadequate grounding can cause
serious injury or death.
Before installing the controller or remote devices, ensure that the
indoor and outdoor unit operation has been stopped. Further, be sure
to wait at least five minutes before turning off the main power switch to
the indoor or outdoor units. Otherwise, water leakage or electrical
breakdown may result.
Do not open the service cover or access panel to the indoor or outdoor
units without turning OFF the main power supply. Before connecting or
servicing controller or cables to indoor or outdoor units, open and tag
all disconnect switches. Never assume electrical power is
disconnected. Check with meter and equipment.
Use an exclusive power supply at the controller’s rated voltage.
Be sure to install circuit breakers (ground fault interrupter, isolating
switch, molded case circuit breaker, and so forth) with the specified
capacity. Ensure that the wiring terminals are tightened securely to
recommended torque specifications.
This equipment can be installed with a Ground Fault Circuit Breaker
(GFCI), which is a recognized measure for added protection to a
properly grounded unit. Install appropriate sized breakers / fuses /
overcurrent protection switches, and wiring in accordance with local,
state and NEC codes and requirements. The equipment installer is
responsible for understanding and abiding by applicable codes and
requirements.

4 Installation and Removal
4.1 Connection of Signal Wire of the Wired Zone Controller
●Open the cover of the electrical control box of the indoor unit.
●Place the single line of the wired zone controller through the rubber ring.
●Connect the signal line of the wired zone controller to the 4-pin socket of the indoor unit
PCB.
●Tighten the signal wire with ties.

Please pay special attention to the following during the connection to avoid malfunction of the
air conditioning unit due to electromagnetic interference (EMI).
1)
Separate the signal and communication cables of the wired zone controller from the
power cord and connection cables between the indoor and outdoor unit with a minimum
interval of 8 in. (20cm). Otherwise, the communication of the unit will probably work
abnormally.
2)
If the air conditioning unit is installed where it is vulnerable to electromagnetic interference
(EMI), then the signal and communication cables of the wired zone controller must be
shielded communication cable.

Fig.4.2
Fig.4.2 shows the installation steps for the wired zone controller. Pay attention to the following
before completing the installation.
1) Prior to the installation, first DISCONNECT THE POWER SUPPLY of the wire buried in the
installation opening. No operation should be performed with the power on during the entire
installation.
2) Pull out the four conductor twisted pair cable from the installation opening and then place it
through the rectangular opening behind the soleplate of the wired zone controller.
3) Place the soleplate of the wired zone controller on the wall over the installation opening
and secure it with screws M4X25.
4) Insert the four conductor twisted pair cable into the slot of the wired zone controller and then
secure the front panel and the soleplate of the wired zone controller together.
5) Finally, secure the front panel and the soleplate of the wired zone controller tightly with
screws ST2.9X6.
