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

1. DANGER identifies the most serious hazards which will result in

severe personal injury or death.

2. WARNING signifies hazards that could result in personal injury or

death.

3. 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 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.

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 the 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)

PERSONAL INJURY, DEATH AND / OR PROPERTY DAMAGE
