NOTE: On a multi--split system (38/40GXM), simultaneous
cooling and heating is not allowed. Setting the mode (cool or

determine the allowable mode on the other fan coils. If there is
a mode conflict, E7 error will be displayed on the unit with the
conflict. Turn unit off and select allowed mode.

ward the unit and pressing the “TEMP” and then the “+”

screen.

NOTE: If unit is operating in Dry mode, low fan speed will be
displayed and the fan speed cannot be changed.

louvers default to the cooling or heating position. The user
can adjust the default louver position by pushing the
”SWING” button. The louver will start to swing. If a sta-
tionary position is desired, push the

of the LED display on the front panel. The

appear for a short period of time on the remote control when the
command is entered. The unit will emit an audible beep when the
signals are received correctly.
