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. See Fig. 1.

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 or call 1-800-227-7437.

The high wall fan coil unit can be set up and operated from the remote control (provided). See Fig. 2. 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 5 operating modes:

•Fan only

•Auto (heat pump models only)

•Heating (heat pump models only)

•Cooling

•Dehumidification

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.

If the room temperature is 2° F lower than the set point, the system will operate in Heating mode. If the room temperature is 2° F higher than the set point, the system will operate in Cooling mode.

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

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

DEHUMIDIFICATION — In Dehumidification mode, the system dries, filters and slightly cools room air temperature. This mode does not take the place of a dehumidifier.

NOTE: Two settings are available for use with selected modes. The Turbo setting provides maximum capacity. The Economical setting provides quiet, energy saving operation. Cooling and Heating modes can be operated in either the Turbo or the Economical setting. The Dehumidification mode can be operated in the Turbo setting, and the Auto mode can be operated in the Economical setting. See the Using the Turbo Setting or Using the Economical Setting sections for more information.

Remote Control (Fig. 2-6) — The remote control transmits commands to set up and operate the system. The controller has a window display panel that shows the current system status. The controller can be secured to a surface when used with the mounting rack provided. See Fig. 2.
