SAFETY PRECAUTIONS
1-Safety Precautions
Read Before Using
Incorrect usage may cause serious damage or injury.
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 fire. 3. Moving and re-installation must be performed by
professionals. Failing to do so may lead to abnormal
operation or fire. 4. Do not install the unit in a place that is vulnerable to
flammable gas leakage. Leakage of flammable gas
could lead to fire. 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 fire. 8. For wiring, use only the cables specified. Do
not subject the terminal to external force. This could lead to
the wire becoming damaged and result in fire. 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 flex or rigid conduit at 12-20
inches (300-500mm) or above. 11. The shielded cable of the wired controller
must be firmly grounded. 12. DO NOT use an insulation resistance tester.

INSTALLATION
4-Unit Installation
Step 1: Remove the upper section of unit
Insert a flat head screwdriver into the slots located at the bottom of the
wired controller (2 places). Remove the front cover. (See fig. 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 flat 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 fig. 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 flat surface. Be careful not to distort the back plate of the wire
controller by overtightening the mounting screws.

4 INSTALLATION
Step 3: Battery Installation
NOTE Put on a flat surface. Be careful not to distort the back plate of the
controller by over-tightening the mounting screws.
· 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 first 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 fixed and cannot be
pulled.

4 INSTALLATION
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.
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.
NOTE Wired controller with wireless function does not have this function.
9

4 INSTALLATION
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.
