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.
