A NOTE ABOUT SAFETY
Any time you see this symbol in manuals, instructions and on the unit, be
aware of the potential for personal injury.
There are 3 levels of precaution :
DANGER identifies the most serious hazards which results in severe
personal injury or death. WARNING signifies hazards that could result in
personal injury or death. CAUTION is used to identify unsafe practices
which could result in minor personal injury or product and property
damage.
NOTE is used to highlight suggestions which results in enhanced
installation, reliability, or operation.
GENERAL
The floor console fan coil unit provides quiet, maximum comfort.
In addition to cooling and/or heating, the floor console fan coil unit
matched with an outdoor condensing unit filters and dehumidifies the air
in the room to provide maximum comfort.
IMPORTANT: The floor console fan coil unit should be installed by
authorized personnel only; using approved tubing and accessories. If
technical assistance, service or repair is needed, contact the installer.
The floor console fan coil unit can be set up and operated from the remote
control (provided). If the remote is misplaced, the system can be operated
from the AUTO setting on the unit.
Operating Modes
The floor console unit has five operating modes:
• FAN Only
• AUTO
•HEATING
•COOLING
• DEHUMIDIFICATION (DRY)
FAN Only
In the FAN Only mode, the system filters and circulates the room air
without changing room air temperature.
AUTO
In the AUTO mode, the system automatically cools or heats the room
according to the user-selected set point.
NOTE: AUTO mode is recommended for use on single zone
applications ONLY. Using AUTO CHANGEOVER on multi-
zone applications could set an indoor unit to STANDBY mode,
indicated with two dashes (--) on the display, which will turn off
the indoor unit until all the indoor units are in the same mode
(COOLING or HEATING). HEATING is the system's priority
mode. Simultaneous HEATING and COOLING is not allowed.
HEATING
In the HEATING mode, the system heats and filters the room air.
COOLING
In the COOLING mode, the system cools, dries and filters the room air.
DEHUMIDIFICATION (DRY)
In DEHUMIDIFICATION mode, the system dries, filters and slightly
cools the room air temperature. This mode prioritizes air
dehumidification but it does not take the place of a dehumidifier.
Wireless Remote Control
The remote control transmits commands to set up and operate the system.
The control has a window display panel that displays the current system
status. The control can be secured to a surface when used with the
mounting bracket provided.
Wired Remote Control (Optional)
Refer to the Wired Controller manual.
24V Interface (Optional)
Allows the control of the Ductless System with a third party thermostat.
PERSONAL INJURY, DEATH AND / OR PROPERTY
DAMAGE HAZARD

REMOTE CONTROL
IMPORTANT: The wireless remote control can operate the unit from a
distance of up to 26 ft. (8 m) as long as there are no obstructions.
NOTE: If a wireless remote controller is used, relocate the IR
(Infrared) receiver within the line of sight of the remote
location using the 6 ft. cable (included). The factory location
of the IR receiver is inside the control box. An authorized
technician should perform this work.
When the timer function is used, the remote control should be kept in the
vicinity of the unit (within 26 ft. (8 m).
The remote control can perform the following basic functions:
• Turn the system ON and OFF
• Select the operating mode
• Adjust room air temperature set point and fan speed
Refer to the “WIRELESS REMOTE CONTROL” on page 4 for a
detailed description of all the capabilities of the remote control.

Two AAA 1.5v alkaline batteries (included) are required to operate the
remote control.
To install or replace batteries:
1. Slide the back cover off the control to open the battery compartment.
2. Insert the batteries. Follow the polarity markings inside the battery
compartment.
3. Replace the battery compartment cover.
NOTES:
1. When replacing batteries, do not use old batteries or a different
type of battery. This may cause the remote control to malfunction.
2. If the remote is not going to be used for several weeks, remove the
batteries. Otherwise, battery leakage may damage the remote
control.
3. The average battery life under normal use is about 6 months.
4. Replace the batteries when there is no audible beep from the
indoor unit or if the Transmission Indicator fails to light.
5. When batteries are removed, the remote control erases all
programmed settings. The control must be reprogrammed after
the insertion of new batteries.
