WARNING

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 will filter and
dehumidify 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.

S Fan only
S Auto
S Heating (heat pump models only)
S Cooling
S Dehumidification (DRY)

Fan Only

In Fan Only mode, the system filters and circulates room air
without changing room air temperature.

Auto

In Auto mode, the system will automatically cool or heat the room
according to the user--selected set point.

Heating

In Heating mode, the system heats and filters room air.

Cooling

In Cooling mode, the system cools, dries and filters room air.

Dehumidification (DRY)

In Dehumidification mode, the system dries, filters and slightly
cools room air temperature. This mode prioritizes air
dehumidification but it does not take the place of a dehumidifier.

Remote Control

The remote control transmits commands to set up and operate the
system. The control has a window display panel that shows the
current system status. The control can be secured to a surface
when used with the mounting bracket provided.
