WALL MOUNT CONTROL FUNCTIONS
Basic Functions
ON/OFF
Press On/Off to turn ON your Indoor Unit. Pressing this button again will turn OFF the Indoor Unit.
The illustrations show how your Wall Control Unit will appear when your system is ON or OFF.
The temperature setting range is 61-86°F or 16-30°C under the COOL mode.
MODE
While your Indoor Unit is ON, you can select what mode you would like it to operate in. When pressed
the Mode button will cycle through the operating settings in the following order:
AUTO – COOL – DEHUMIDIFY – FAN - HEAT
TEMPERATURE
Press to increase or to decrease the set temperature. Holding down the or button will increase or
decrease the set temperature 1°F every 0.5 seconds.
In COOL, DEHUMIDIFY, FAN or HEAT Modes the temperature range is 61-86°F or 16-30°C.
In AUTO mode the temperature setting is not adjustable.
FAN
When your Indoor Unit is ON, the FAN button allows you to control the Fan Speed. The Fan button will cycle
through the operating settings in the following order:
AUTO – LOW – MEDIUM - HIGH
AUTO
AUTO Mode is a factory preset that will automatically switch your system between HEAT and COOL to
maintain 77°F.
Mode Conflicts
All Indoor Units on the same system MUST run in the same mode, either all COOL or all HEAT. With a 2 (or
more) Indoor Unit system, you cannot run one Indoor Unit in COOL Mode and another in HEAT. Attempting
to do this will create a mode conflict, and you will receive an E7 Error Message on your Indoor Unit Display,
additionally all Indoor Units will not run until mode selection is the same Mode setting on all Indoor Units.
Also, if you have set the TIMER ON function, and the mode for that Indoor Unit conflicts with other Indoor
Units operating when the TIMER ON function attempts to turn the system on, it will also create a Mode Conflict
and shut down the Indoor Unit.
In the event a restart doesn’t clear the error, you may need to shut power off to the outdoor unit and the entire
system, wait approximately 10 minutes, restore power and restart the system, making sure all Indoor Units are
in the same Mode.
