MULTI-ZONE OPERATION
The Multi-Zone mini-split will operate each zone in either cooling or heating mode but not both. The unit will not
operate as one zone cool and another heat. If this occurs, an E7 error will be displayed. To clear this error, make
sure all indoor units are in the same mode either heat or cool. Each zone will control the room temperature at
set-point and allow all normal fan, swing, turbo, timer, and sleep functions.
Emergency Operation (Aux. Switch)
In the event that the remote controls are misplaced, you can operate your
inside unit by carefully raising the cover and pressing the emergency
operation switch located under the lower right hand corner of the cover.
To open the front cover, place fingers in the bottom of the slots on the side
of the indoor unit and gently pull outward. To close the cover, press down on each end and center of
the cover to latch.
DO NOT OVER EXTEND THE FRONT COVER.
If the unit is off, pressing the Aux. button will start the unit
in the default AUTO mode. Press the button again and it
will stop the unit.
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 switches to HEAT mode. If the temperature goes above 77 °F unit switches to COOL mode. If
temperature is in between 68 °F to 77°F the unit runs in the FAN mode.

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.

Problem Troubleshooting
The unit does not run.
•Is the power off?
•Is the circuit protection device tripped?
•Is voltage too high or low?
(Tested by a professional)
•Is the Timer on?
•A 3 minute delay occurs before each compressor start.
Cooling and or Heating efficiency
is not good.
•Is temperature setting correct?
•Are the inlet or outlet vents obstructed?
•Is the filter clean?
•Are windows and doors closed?
•Is fan set to low speed?
•Is there a heat source in the room?
Wireless remote control is not
working. (See Note 2)
•Reset unit. Disconnect main power for 30 seconds then
reapply.
•Is it within receiving range? Is it obstructed?
•Replace the batteries.
•Is remote control damaged?
Water leaking into room.
•The air humidity is excessively high. Check to see if all
windows and doors are closed.
•Call service Tech if not corrected by the above action.
Water leakage in outdoor unit.
•When the unit is running in Auto Defrosting mode, ice will
thaw and drip into pan.
•When the unit is running in HEAT mode, the water
adhered to the condenser coil drains into pan.
Noise from indoor unit emitted.
•When defrosting is started or stopped, it will makea
sound. This is due to the refrigerant flow reversing
directions.
•Normal refrigerant flowing in unit.
If E7 error code occurs, indoor units are in conflict. All units must be the same mode.
Notes:
1) If an error other than E7 is being displayed on the temperature display, it will be necessary to
call a service Tech for repair.
2) An audible beep will be heard, when a button is pressed, if the remote control is
communicating with the receiver.
