MODES OF OPERATION,
FUNCTIONS AND FEATURES
The air conditioner is based on a microcomputer control
system with remote wall mounted LCD display and control
unit, programmed for the following modes and functions:
COOL
Cools, dehumidifies and filters the room air. Maintains
desired site temperature.
HEAT
Heats and filters the air. Maintains desired site temperature.
AUTO
Automatically switches from COOLING to HEATING or from
HEATING to COOLING, maintaining the desired
temperature according to the room conditions.
DRY
Dehumidifies and moderately cools the room. In DRY Mode
the air conditioner operates at an increased dehumidifying
power. This function is recommended to be used when
temperature is rather cool but the humidity is high.
FAN
Recalculates and filters the room air. Maintains constant air
movement in the room.
AUTO FAN
The air conditioner automatically selects the FAN speed in
accordance to the room temperature. At the start, the unit
operates at high fan speed. As the room air gets closer to the
desired temperature, the fan switches on a lower speed for
quieter operation.
HOT KEEP
In HEATING and in AUTO FAN, the fan will be turned off
when the compressor is not in operation and will not be
restarted, unless the indoor coil reaches adequate
temperature. This HOT KEEP feature prevents
uncomfortable cold air drafts. AUTO FAN Is therefore,
recommended to be used when the air conditioner is in
HEATING mode.
ROOM TEMP.
Measures and displays room temperature.
10
E N G L I S H
I FEEL
Switches the temperature sensing point to the place where
the remote control is located (in normal operation the
temperature sensor is located behind the intake grille of the
air conditioner). This function is designed to provide a
personalized environment by transmitting the temperature
control information from where the remote control is
placed. The communication between the remote control
and the central control unit is done by infrared signal.
When using this function, the remote control should
always be aimed without obstructions at the air conditioner.
TIMER
Real time control and display, automatically turns the air
conditioner ON or OFF according to the time of day setting,
ensuring comfort conditions before returning home,
without wasting electricity. It turns off the air conditioner
automatically when sleeping.
SLEEP
Designed to automatically reset the temperature setting. In
COOLING mode the temperature rises one degree
centigrade after each consecutive hour, up to three hours,
from the start of the mode. In HEATING mode, the reverse
occurs, the air conditioner lowers its temperature one
degree every hour. When in SLEEP Mode, the operation
will automatically turn off after seven hours. This function
saves energy when the air conditioner is operating during
off hours.
3-MIN DELAYED
RUN
The compressor is protected by a three minute delayed
restart.
MEMORY
The microprocessor retains the last data entry whether or
not the unit is plugged in. Therefore, when the unit restarts
after a power disruption or power failure, it will resume
operation in the same mode as before the power
disruption.
LOCK
Freezes the last operation setting on the remote control.
When LOCK is activated, the remote control will not be
able to control the air conditioner.
12
E N G L I S H
Aim at the infrared signal receiver on the central control
unit when operating.
The remote control signal can be received at a distance of
up to 8 m.
Be sure that no obstructions exist between the remote
control and the signal receiver.
Do not drop or throw the remote control unit.
Do not place the remote control unit in a location
exposed to direct sunlight, or next to a heating unit, or
any other heat source.
