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 (Dehumidication) 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 (Dehumidication) 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.

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
conrm 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 denitions.
• 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.

(1) The rst high wall indoor unit to
connect with WK-B is considered as
master unit 0.
(2) Remove the jumpers on CN3 and CN4.
(3) The wired control must connect to CN1
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
switches o (master).
