power button will illuminate to indicate the power is on. The backlight on

of inactivity. The remote control can also be used to turn power ON / OFF
(See Remote Control).

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.

When the
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
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
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.
