SAFETY PRECAUTIONS
1
Incorrect usage may cause serious damage or injury.
Read Before Using
WARNINGS FOR PRODUCT INSTALLATION
INSTALLATION MUST BE PERFORMED BY AN AUTHORIZED DEALER OR SPECIALIST. DEFECTIVE
INSTALLATION CAN CAUSE WATER LEAKAGE, ELECTRICAL SHOCK, OR FIRE.
1. Follow all steps detailed in this manual.
2. Improper installation could lead to electric shock or re.
3. Moving and re-installation must be performed by professionals. Failing to do so may lead to abnormal
operation or re.
4. Do not install the unit in a place that is vulnerable to ammable gas leakage. Leakage of ammable gas
could lead to re.
5. Do not install in a location with oil, vapor, or sulfured gas, as the unit can become deformed, leading to
system malfunction.
6. Do not operate the thermostat with wet hands or let water enter the thermostat. Otherwise, electric shock
could occur.
7. Ensure the wiring corresponds with the thermostat's current requirements. Failing to do so could cause
electrical leakage and re.
8. For wiring, use only the cables specied. Do not subject the terminal to external force. This could lead to
the wire becoming damaged and result in re.
9. Refer to the wiring diagram included in this manual to connect the wired controller to the indoor unit.
10. The wired controller works in a low voltage loop circuit. DO NOT directly connect the cable to high voltage
(115V, 220V). Keep a clearance between the ex or rigid conduit at 12-20 inches (300-500mm) or above.
11. The shielded cable of the wired controller must be rmly grounded.
12. DO NOT use an insulation resistance tester.
BATTERY WARNINGS-KEEP OUT OF REACH OF CHILDREN
INGESTION HAZARD: Contains button cell or coin battery.
• If the battery compartment does not close securely, stop using the product and keep it away from children.
• If batteries may have been swallowed or placed inside any part of the body, seek immediate medical
attention.
• Swallowing can lead to chemical burns, perforation of soft tissue, and death. Severe burns can occur within
2 hours of ingestion. Seek medical attention immediately.
• Remove and immediately recycle or dispose of used batteries according to local regulations and keep away
from children. DO NOT dispose of batteries in household trash or incinerate. Even used batteries can cause
severe injury or death.
• Non-rechargeable batteries are not to be recharged.
• Call a local poison control center for treatment information.
• Do not force discharge, recharge, disassemble, heat above the manufacturer's specied temperature
rating, or incinerate. Doing so may result in chemical burn injuries due to venting, leakage, or explosion.
• Ensure the batteries are installed correctly according to polarity (+ and -).
• Do not mix old and new batteries or dierent brands of types of batteries, such as alkaline, carbon-zinc, or
rechargeable batteries.
• Remove and immediately recycle or dispose of batteries from equipment not used for an extended period
of time according to local regulations.
• Battery type: CR2032
• Battery Power Supply: 3.0V

4-Unit Installation
Step 1: Remove the upper section of unit
Insert a at head screwdriver into the slots
located at the bottom of the wired controller (2
places). Remove the front cover. (See g. 4-1)
NOTE: Do not pry up and down, only rotate
the screwdriver.
NOTE
The Printed Circuit Board (PCB) is mounted in the upper part of the wired controller. Use care not to
damage the board with the at head screwdriver.
Step 2: Attach Back Plate
For exposed mounting, fasten the back plate to the wall with 3 ST3.9*24 screws and plugs. (See g. 4-2)
Use 2 M4X25 screws to install the back cover of the 86 switch box, and use 1 ST3.9*25 screw to attach
to the wall.
NOTE
Attach to a at surface. Be careful not to distort the back plate of the wire controller by over-
tightening the mounting screws.

Step 3: Battery Installation
• Put the battery into the battery compartment, ensuring the positive
side of the battery is in accordance with the positive side of the
compartment.
• Set the correct time during the rst operation.
• Batteries in the wired controller can keep time after a power failure.
When power is restored, the time display should still remain correct.
If it is incorrect, replace the battery and reset the time.
Step 4: Indoor Unit Wiring
• Using pliers or a similar tool, notch the section for the wiring to pass through.
• Connect the terminals on the remote controller (HA, HB), and the terminals of the indoor unit (HA,
HB). (HA and HB do not have polarity. See Fig. 4-5.)
NOTE
• DO NOT allow water to enter the wired controller. Use the trap and putty to seal the wires.
• The connecting wires must be xed and cannot be pulled.
NOTE
Put on a at surface. Be careful not to distort the back plate of the
controller by over-tightening the mounting screws.

mrcool.com9
INSTALLATION
4
The main/secondary wired controller can be used to enable two wired controllers to control one
unit. The wired controllers connect to the unit's HA and HB ports through the HA and HB port on the
controller. There is no polarity between HA and HB. See Fig. 4-7.
For some units, the wired controller connects to the unit HA and HB ports through the HA and HB
ports. There is no polarity between HA and HB. See Figure 4-6.
NOTE
Wired controller with wireless
function does not have this
function.

INSTALLATION
4
For some units, one wired controller can support multiple units (a maximum of 16 units). In this case,
the wired controller and unit need to be connected to the HA and HB ports at the same time. Please
note: In group control, there will be no errors displayed on the wired controller.
Step 6: Reattach upper section of unit
Adjust the upper section, then attach. Avoid accidental clamping of the wiring when reattaching the
front face of the controller. See Fig. 4-10.
NOTE
The illustrations in this manual are for
explanatory purposes only. Your actual
controller design may vary from what is
shown here.
