severe personal injury or death.

 signifies hazards that could result in personal injury or 

death.

in minor personal injury or product and property damage.

NOTE

 is used to highlight suggestions which will result in enhanced 

installation, reliability, or operation.

GENERAL

The high wall fan coil unit provides quiet, maximum comfort. In 
addition to cooling and/or heating, the high wall fan coil unit matched 
with an outdoor condensing unit filters and dehumidifies the air in the 
room to provide maximum comfort.

IMPORTANT:

 The high wall 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 high wall 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 high wall fan coil unit has five operating modes:

• FAN Only
• AUTO
• HEATING (heat pumps only)
• 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.

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.
