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.
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 set-
ting. Use TEMP+/- buttons to adjust the compensation. Compensa-
tion 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.
