REMOTE CONTROL FUNCTIONS
Note: Be sure there are no obstructions between the remote control and the receiver. Remote
control units are interchangeable, and are not assigned to a particular indoor unit. Indoor
controller will beep each time it receives a command from the remote control. Keep the remote
control away from moisture and excessive heat.TIP: Each remote will control any or all the indoor
units.
ON/OFF -Turns the unit on or off. There is a 3 minute compressor delay when the unit is turned
on.
MODE –Pressing the MODE button will select between AUTO, COOL, DRY, FAN, or HEAT.
AUTO mode - Set point temperature will not be shown on the remote control display and
cannot be changed. Temperature is automatically set to 68 °F to 77 °F and will switch
between COOL, HEAT or FAN mode to maintain the temperature. If the temperature
goes below 68 °F the unit will switch to HEAT mode. If the temperature goes above 77 °F
unit switches to COOL mode. If temperature is in between the temperatures it runs in the
FAN mode.
On rare occasions while running in the AUTO mode with other zones activated there may
be an “E7” error code. “E7” error code occurs when 2 or more units are set to run in
different modes, such as HEAT and COOL. In the AUTO mode the unit automatically
switches between HEAT, COOL or FAN. If other zones are set to HEAT or COOL while
the AUTO is running in an opposite mode an “E7” will occur. To rectify this condition you
must set all the indoor units to the same mode, either HEAT or COOL, or leave the unit
alone and when the temperature returns to the point where the unit switches back to the
correct mode (as the other indoor units) and all zones are in the HEAT or COOL mode, it
will clear itself and begin to run again.
COOL mode –Unit cools room to set point temperature. Set point temperature can be set
from 61 °F to 86 °F. Outdoor unit will operate in outside temperatures of +4 to +118 ºF in
the cooling mode. Indoor fan does not turn off in the cooling mode when temperature set
point has been satisfied. It will continue to run to keep the room temperature consistent.
HEAT mode - Unit heats room to set point temperature. Set point temperature can be set
from 61 °F to 86 °F. Outdoor unit will operate in outside temperatures of -5 ºF to +75 ºF in
ON/OFF –Turns unit on or off.
-/+ - Raise, Lower set point.
FAN –Set fan speed, hi, med, lo, auto.

the heating mode. Indoor fan will turn off in heating mode when temperature set point has
been satisfied.
DRY mode –Set point temperature can be set from 61°F to 86°F. Unit cools at 90%
capacity while the FAN runs in LOW speed only (FAN speed cannot be changed).
FAN mode –Selects fan only operation. Set point temperature can be set from 61 °F to
86 °F. Fan speed can be set to AUTO, HIGH, MEDIUM or LOW.
SLEEP –In the COOL mode adjust the set-point temperature to a comfortable setting, and then
press the SLEEP button. After 1 hour, the set-point will increase by 1.8 ºF (1 ºC). After 2 hours
have passed temperature is increased by 3.6 ºF (2 ºC). Temperature will never increase more
than 3.6 ºF (2 ºC) from set-point or beyond 86 ºF (30 ºC). The temperature will stay at this setting
until the unit is turned off or the SLEEP function is disabled.
In the HEAT mode adjust the set-point temperature to a comfortable setting, and then press the
SLEEP button. After 1 hour the set-point will decrease by 1.8 ºF (1 ºC). After 2 hours have
passed temperature is decreased by 3.6 ºF (2 ºC). Temperature will never decrease more than
3.6 ºF (2 ºC) from set point or below 61 ºF (16 ºC). The temperature will stay at this setting until
the unit is turned off or the SLEEP function is disabled.
The SLEEP mode does not work in the FAN or AUTO modes and is deactivated when the unit is
turned off or power is lost. On power up, the SLEEP mode must be turned on again if needed.
Press the SLEEP mode button to toggle SLEEP mode off and return to normal operation.
FAN –Press this button to change fan speeds, AUTO, HIGH, MEDIUM or LOW, while in the
HEAT, COOL, FAN modes. When in the AUTO setting, the fan will run faster the further away
from the set point it gets. On the other hand the closer it gets to the set point the slower it will run.
CLOCK –Press the CLOCK button, the clock ICON will start to blink. It will only blink for 5
seconds. While blinking press and hold down the + or - keys to adjust the 24H time of day clock
to the correct time. You must immediately press the CLOCK button to set the time. If the CLOCK
button is not pressed within 5 seconds, the clock time will revert back to the original setting and
clock will have to be set again.

House with thermometer inside –Displays set point
House with thermometer outside –Displays set point
PURGE –When in the COOL or DRY mode and the PURGE function is enabled, the fan will
continue to operate for 10 minutes after the unit is turned off. This function dries the evaporation
coil to prevent mold and mildew. The PURGE function will remain enabled in DRY and COOL
unless power is interrupted or is disabled by the button. PURGE will not work in AUTO, FAN or
HEAT modes.
TURBO –The TURBO function will only run while in the HEAT or COOL mode. TURBO
increases indoor fan speed (more than high fan speed).
+ / - Raises or Lowers the set point temperature. Holding the button down for more than 2
seconds will cause the set point to auto increment or decrement. This does not function in the
AUTO mode since the temperature set point can not be changed.
DISPLAY –Turns the display on or off on the indoor unit. None of the lights will be illuminated
when off is selected.
LOUVER UP AND DOWN –Pressing the LOUVER positioning button slowly, (more than 2
seconds) will start and stop the louver swing. If the button is pressed to turn on swing and then
pressed again to turn it off, the louvers will remain in that fixed position until it is turned on again.
