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.

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.
SFan only
SAuto
SHeating (heat pump models only)
SCooling
SDehumidification (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.
