Temperature Adjustment Keys: /

• Press the TEMP+ or TEMP- keys to change the temperature by

1°F increments.

• The temperature set point range for Auto, Cooling, Heating

and Dry (Dehumidication) is 60°F~86°F (If ECO is on,

then temperature range will change per the ECO setting

parameters).

• The temperature is set independently under Auto, Cooling,

Heating and Dehumidify modes. Once the temperature is set

in each mode the setting will be saved for that mode.

• In fan mode, Temp +/- keys do not work.

Adjust ECO Parameters:

• Cooling: Power on the unit. Adjust set temperature to 86°F.

Press and hold FAN and TEMP+ for 5 seconds. The minimum

allowable set temperature will be displayed in the top right

corner. Use TEMP+/- to change the parameter, then press FAN

save. The default minimum temperature is 73°F.

• Heating: Power on the unit. Adjust set temperature 60°F.

Press and hold FAN and TEMP- for 5 seconds. The maximum

allowable set temperature will be displayed in the top right

corner. Press TEMP+/- to change the parameter, then press

FAN to save. The default maximum temperature is 79°F.

• Dry (Dehumidication) ECO parameters are the same as Cooling.

Child Lock:

• Press and hold TEMP+ and TEMP- for 5 seconds to activate/

deactivate the Child Lock function. When the Child Lock

function is active, will appear.

Central/Lock Function: /

Function is active only when system has a central control, such as

the YCZ-A004. This setting is activated only by the central Control.

Fahrenheit Setting and Display:

• Fahrenheit to Celsius: Adjust set temperature to lowest

setting; 60°F when ECO is o. Press and hold TEMP- for 15

seconds. During the 15 second count the display will beep

once at 5 seconds and display error codes. Then after another

5 seconds, the display will beep once again and display 00,

after 5 more seconds the display will change to Celsius.

• Celsius to Fahrenheit: Adjust set temperature to highest

setting; 30°C when Eco is o. Press and hold TEMP+ for 15

seconds. During the 15 second count, the display will beep

once at 5 seconds and enter Special Functions menu. Then

after another 5 seconds, the display will show 00, after 5 more

seconds the display will change to Fahrenheit.

Lock Settings / Fahrenheit Setting

Central Control On/O function only available.

Central Lock No functions available.

Set Temperature Compensation:

• With the display o, press and hold the FAN button for 5 seconds. The

display will then show 0 (default) or current compensation setting. Use

TEMP+/- buttons to adjust the compensation. Compensation can be

set in 1° increments

+/- 8°F (0.5°C increments up to +/-4°C).

• Temperature compensation changes the ambient temperature

reading. If the system is sensing the ambient temperature at 72°F

and the compensation is set to -2° then the system will use 70°F in its

operation to heat or cool.

Forced Defrost:

• Set to Heating mode, high fan, and 86°F (30°C), or highest temperature

if ECO is on. Press TEMP+ 6 times within 5 seconds. Three tones will

conrm that the unit is in forced defrost mode.

Forced Cooling:

• Set mode to Cool. Tap ON/OFF. Tap any button, except ON/OFF, to

light the display. Press and hold ON/OFF for 5 seconds. LL will display

and the control will beep twice. To exit, turn o control and turn it on

again.

Forced Heating:

• Set mode to Heat. Tap ON/OFF. Tap any button, except ON/OFF, to

light the display. Press and hold ON/OFF for 5 seconds. HH will display

and the control will beep twice. To exit, turn o control and turn it on

again.

How to check error:

• If there is an error, will display.

• Check error: Press and hold TEMP- button for 5 seconds. The

error history will appear in the top right corner. The current

error will appear in the middle of the screen. If there is no error,

“--” will display.

Mode Restriction Function:

• When SW2-1 is on, the system mode lock is on. This will lock

the mode to Heat, Cool, Dry or Fan. No button press can

change mode. All other control functions are available such as

fan speed, set temperature, and on/o.

• Mode can still be changed with a wireless control, another

wired control, or a central control.

• When setting mode lock, have control set to desired mode. Set

dipswitch SW2-1 to ON. Disconnect and reconnect system

power.

Checking Parameters (only applies to some models):

• Press and hold TEMP+ for 10 seconds to check the parameters.

The parameters will appear in the middle of the screen to

show indoor address (00-15), Letters will appear after decimal

display (AbCdEF). The detailed parameters will show on the top

right corner. See table for denitions.

• If the control is connected to multiple indoor units, each indoor

unit can be viewed by pressing the FAN button. Then use

TEMP+/- to switch between connected indoor units.

of the WK-B master unit (unit 0).

(4) Connect the CN2 on the master unit

(unit 0) to the next WK-B slave unit (unit 1)

CN1 or CN2. Only the master unit (unit 0)

must use CN1 for the control. All others

may use CN1 or CN2. See Picture 2.2.

(5) Set the dipswitch address of the

WK-B adapter. The adapters ship with all
