Remote Control - Refer to Figure 340A during operation description.
Getting Started - Install two (2) AAA batteries in the battery compartment located on the back of the unit.
Operation - The remote control should be within 25 feet of the air conditioner for operation (refer to Figure 340B for effectiveness).
Press the power button to turn the remote on. The remote will automatically power off after 15 seconds if the buttons are not
being pressed. The remote must be on to control the unit.
POWER Button - Turns remote and unit on and off.
MODE Button - Allows the user to sequentially select the following: AUTO,
COOL, HEAT, and FAN ONLY operations. When the button is pressed, the display
indicates which mode has been selected via a display message. Note that when
the heating function is not available, the system will automatically skip the HEAT
mode.
FAN Button - Selects between automatic (AUTO FAN) or CONTINUOUS operation.
In the AUTO FAN mode, the fan only turns on and off when the compressor
operates or the heat function is enabled.
NOTE: AUTO FAN is not available in the FAN ONLY Mode, the display indicates
CONTINUOUS. In the CONTINUOUS mode, fan speed is determined by your
selection on the FAN SPEED button.
SPEED Button - Used to sequentially select new fan speed, plus AUTO
operation. When the FAN SPEED button is pressed, the fan speed icon
(triangle) changes to indicate the new speed level. Fan speed automatically
varies depending on the set temperature on the control panel and the actual
room temperature. For example, if there is a big difference between your
set temperature and the actual room temperature, the system fan speed
increases to HIGH. It remains at this speed until the room temperature
matches the set temperature.
UP and DOWN Arrows - Pressing either the 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.
Remote Effectiveness
Handheld Remote - Has an operating range
of up to 25 ft. The infrared remote control
signal must have a clear path to transmit
the command to the air conditioning unit.
The remote signal has some ability to
“bounce” off of walls and furniture similar
to a television remote control. The diagram
below shows the typical operating range of
the control in a standard room with 8 ft high
ceilings.
