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 s hould 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 u nit.
Operating Modes:
The high wall fan coil unit has five operating modes:
• Fan only
• Auto
• Heating (heat pump models only)
• Cooling
• Dehumidification (DRY)
Fan Only
In Fan Only mode, the system filters and circulates the room air
without changing room air temperature.
Auto
In Auto mode, the system automatically cools or heat~ the room
according to the user-selected set point.
Heating
In Heat ing mode, the system heats and filters the room air.
Cooling
In Cooling mode, the system cools, dries and filters the room air.
ehu i tier ion mode, the system dries, filters and slightly
s■1 a ir temperature. This mode prioritizes air
dehu midiucation but it does 1101 take the place of a dehumidifier.
