3. Please attach controller top into mounting plate, then press bottom portion to lock controller into place.

- Ensure that controller is installed flush.

- Before locking controller into place, make sure the

communication cable is clear of the internal circuity.

To separate the controller from the mounting plate, use a small blade screwdriver or similar tool and insert into holes below controller and turn clockwise, controller should now pull away easily from the bottom.

- There are two holes below, separate one at a time.

- Take care not to damage internal parts of the controller

when removing from the mounting plate.

4. Please refer to the following directions when connecting the indoor unit and the Thermostat together.

1) Please connect the cables as shown in the figure below when connecting the plug type cable from the

indoor unit’s C/BOX and the housing type of the extension cable.

2) When connecting Terminal Blocks of the indoor C/BOX and the Thermostat with the extension cable, refer

to the steps below.

① Remove the screw on the cable which is fastened to the Thermostat’s Terminal Block by loosening with a

screw driver.

② Remove the housing of the provided 32ft extension cable with a cutting nipper and peel it as shown in the

figure below. (when purchasing the extension cable at the site directly, please peel it as shown in the figure below.)

Please check if the connectors are connected properly.

Installation instruction

③ Make sure each wire is securely fastened under each screw terminal and the wires are not in contact with

each other.

④ Please connect the Terminal blocks of indoor unit’s C/BOX and wired remote controller by referring to the

images and contents shown below. Connect the yellow(signal) part of the Thermostat’s terminal block and the ‘YL’ part of the indoor unit’s terminal block. Connect the red(12 V) part of the Thermostat’s terminal block and the ‘RD’ part of the indoor unit’s terminal block. Connect the black(GND) part of the Thermostat’s terminal block and the ‘BK’ part of the indoor unit’s terminal block.

❈ In case of loose screws or insufficient contact between the terminal and the wire, thermostat may not function

properly.

❈ When the power is off on the Thermostat, check the connection between the Thermostat and Terminal Block.

❈ Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip

the screw head and make tightening difficult.

❈ Over-tightening terminal screw may cut wires or cause irreparable damage to thermostat.

5 Please use an extension cable if the distance between the Thermostat and the

indoor unit is longer than 32 ft (10 m).

• Installation work must be performed in accordance with the national wiring standards and local code by authorized personnel only.

• Apply enclosed noncombustible conduit(metal raceway) or use cable above FT-6 in case of local electric & building code that requires plenum(CMP)cable usage.

• AWG#22, 3 core shielded is recommended when using the large hole in the center of the backplate.

• AWG#24, 3 core shielded is recommended when using the side or top knock-out of the backplate.

CAUTION

When installing thermostat, installation should be flush to a flat wall surface, no installation below the typical wall surface is allow. (Damage to temperature sensor will occur.) Do not install the cable to be 164 ft (50 m) or longer. (Communication error can occur.)
