Let’s check out how to control your air conditioner. On the control panel,
just to the left of the POWER
, is a liquid crystal display (LCD). All of the
control panel function buttons and mode icons can be viewed in Figure 8.
Power On
– Press the
button to turn on the air conditioner. The
power button will illuminate to indicate the power is on. The backlight on
the power switch will automatically dim to 20% intensity after 15 seconds
of inactivity. The remote control can also be used to turn power ON / OFF
(See Remote Control).
Display
– The display is a high ef
fi
ciency LCD with a built-in white back
light. The back light has an automatic two (2) step dim function. After 15
seconds of inactivity, the display dims to 20% intensity. After an additional
120 seconds, the display switches off. Touching buttons will automatically
bring the display to full brightness.
There are four control push buttons on each side of the display.
SYSTEM Button
– Allows the user to sequentially select,
AUTO
Cool
, HEAT , and FAN ONLY operation. Press the
SYSTEM
button and
the display advances to the next mode. A new icon appears. At the same
time, the mode displays for two (2) seconds, then returns the display to
the temperature set point for modes other than FAN. Note that when the
heating function is not available, the system will automatically skip the
HEAT and
AUTO
modes.
FAN MODE Button
– Selects between automatic
AUTO
or
CONTINUOUS
operation. In the
AUTO
mode, the fan only turns on and off when the
compressor operates or the heat function is enabled.
In the FAN ONLY Mode,
AUTO
is not available. The display indicates
CONTINUOUS
. In the
CONTINUOUS
mode, fans speed is determined by your
selection on the
FAN
SPEED
button.
FAN SPEED Button
– Used to sequentially select between fan speeds.
Depending on your model, you can select between LOW, MED, HIGH,
and MAX and AUTO. Max setting not on SL or Kühl + models). When
the
FAN
SPEED
button is pressed, the fan speed is temporarily displayed in the
display window, plus a fan speed icon (triangle) changes to indicate the
new speed level when auto is selected. Fan speed automatically varies
depending on the set temperature on the control panel and the actual
room temperature. Let me explain. Say for example you’re working in
your garage and you need to open the big door for several minutes. The
air conditioner will sense a wide difference between the set temperature
and the actual room temperature when this occurs the system fan speed
increases to MAX. The fan speed decreases (in step) as the temperature
difference decreases. When the set point temperature is reached the FAN
speed returns to the original setting.
SCHEDULE Button
– The
SCHEDULE
button turns the schedule function on
and off. The current day of the week is indicated as a dot underneath
the day symbol. Pressing the
SCHEDULE
button a second time turns the
schedule function off. The schedule function comes preprogrammed with
recommended energy savings values (Addendum 1). The values may
be changed through the schedule program function (See Programmable
Thermostat).
UP and DOWN arrows
– Pressing either
(UP) or
(DOWN) button
changes the desired room temperature. The factory preset lower and
upper limits are 60° F (16° C) and 99° F (37° C). These buttons are also
used to navigate between function options when using the User Menu or
Maintenance Mode.
BACK Button
– This button is used after a menu item has been selected.
It takes the user back to the previous menu level.
DISPLAY/ENTER Button
– This button is used in conjunction with User
Menu and Maintenance Mode operation to select items.
Alerts
– The control system has
fi
ve (5) customer alerts.
