INSTALLATION CONSIDERATIONS
The thermostat should be mounted:
• approximately 48 in. from the floor
• on a section of wall without water or drainage pipes
The thermostat should NOT be mounted:
• where it can be directly affected by the unit’s discharge
airflow
• close to a window, on an outside wall, or next to a door
leading to the outside
• near shelves or curtains that may restrict air movement
• near heat sources such as direct sunlight, heaters, dimmer
switches, and other electrical devices
INSTALLATION
Perform the following procedure to install the thermostat:
1. Turn off all power to the indoor unit.
2. If an existing thermostat is being replaced:
a. Remove existing thermostat from wall or unit.
b. Disconnect wires from existing thermostat. Do not
allow wires to fall back into the wall or unit.
c. Discard or recycle old thermostat.
3. Use 16 to 20 AWG (American Wire Gage), stranded
twisted pair shielded 2-core wiring. Be sure the distance
between the controller and the indoor units is not more
than 820 ft.
4. For exposed wall-hung or under-ceiling/floor units, pro-
vide a 1-in. by 1-in. square opening in the surface behind
the unit to route the shielded 2-core control cable, furred
in to connect the indoor unit display panel to the
controller.
5. For concealed ducted, high-static ducted, cassette, or ver-
tical units, the shielded 2-core cable can be routed
through the plenum and the wall to connect the indoor
unit display panel and the controller.

Indoor Unit Addressing — Each indoor unit must
have a unique address that can be set from 0-63 for proper
system operation.
• Indoor units can be addressed automatically in heat
pump systems. Dip switch “S6” in outdoor unit main
board to 00 (default set in factory) means auto addressing
for each indoor units. When the system is first powered
on, this auto addressing process can take approximately
6 minutes or more, depending on the number of indoor
units in the system.
• Indoor units can be addressed manually using remote
controllers. The whole system, outdoor units, indoor
units and MDC are included, and should be powered on
when setting an address by remote controllers. If “FE”
displays on LED screen of the controller or display board
of indoor unit, there is no address for this unit. After set-
ting all indoor units’ addresses, cut off the power supply
of indoor units and power on again to clear this error.
To manually set indoor unit address, press and hold ROOM
TEMP and SWING together for 3 seconds to enter the follow-
ing menu. It displays FE# 00 if there is no address for this in-
door unit; otherwise it displays current address of the indoor
unit. Clicking TEMP.UP or TEMP.DOWN to change 00 to ad-
dress number you want to set. Then press OK to confirm and
exit the setting interface.
Query Function
Press FAN and OK at the same time and hold for 3 seconds
to open the query function as shown in Fig. 28. The wired con-
troller can query the number of connected IDUs and addresses,
IDU sensor T1/T2A/T2B, and error records.
After entering the query function, the wired controller
displays the IDU address and the total number of connected
IDUs. When the wired controller controls multiple IDUs at the
same time, press TEMP. UP or TEMP. DOWN to select IDUs
with different addresses as shown in Fig. 29.
