n"Up" and o"Down"
Use these keys to scroll the menus.
p"Right" and q"Left"
Use these keys to adjust the values in each menu item.
r"Power"
On/Off switch.
2.2. Screen elements
nRoom temperature: Indicates the current room temperature.
oDesired temperature: Your desired room temperature.
pPower status:
Air conditioner apparatus is on.
Air conditioner apparatus is off.
qSeason setting:
The device is adjusted to work in summer.
The device is adjusted to work in winter.
rFan status: Indicates a schematic of the selected fan speed. The number of the blades is proportional to the
selected fan speed.
Note: The icon just represents the selected fan speed. The device may be on or off due to difference between
room and desired temperature or power status setting of the wall mounted unit.
sAuto: This icon appears if "Auto" mode is selected. It means the device automatically selects the appropriate
fan speed which is proportional to the temperature difference between the room and desired. So by
approaching the desired temperature the fan speed reduces. The feature is called "smooth approach" and is
only available in Ddm xa3/xa5/xa7.
tAnimated icon: It reacts based on temperature difference between the "Desired" and the "Room".
The left icon appears when the room temperature is above the comfort range. Comfort range is up to 1°c
above the "Desired" in summer or up to 1°c below the "Desired" in winter.
The middle icon indicates that the room temperature is in the comfort range.
The right icon shows the room temperature is below the comfort.
uStatus bar: Indicates the "Menu item" you wish to adjust. Use "Up" or "Down" keys to surf through these
menus (Refer to section 2.1 for "Up" and "Down" keys).

4. English / Local
2.4. Menu functions
2.4.1. Fan speed (Menu item 1)
It represents the adjusted fan speed. Use "Left" key to decrease the fan speed or "Right" key to increase it.
Note: If the fan speed is set to its minimum value and "Left" key is pressed, the power status switches off. It
switches on again by pressing the "Right" key.
Notice: Pressing the "Right" key while maximum fan speed is selected enables the "Auto" mode (Ddm
xa3/xa5/xa7 only)(Please refer to section 2.2 for more description on "Auto" mode). You may exit the "Auto"
mode by pressing the "Left" key in "Fan speed" menu, which cause the device to return to maximum fan
speed again.
2.4.2. Desired temperature (Menu item 2)
It is the temperature which you like to maintain your room. The standard set point for comfort condition in
the residential zones is 24°c, but you can set a higher or lower temperature if you wish.
The minimum allowable temperature is 16°c and the maximum is 31°c. You can use "Right" key to increase
the value or "Left" key to decrease it (Refer to section 2.1 for "Right" and "Left" keys). As you change the value
the result appears on the desired temperature section of the screen (Refer to section 2.2 to find the "Desired
temperature" on the screen).
Note: If you set a value much lower than 24°c in summer or much higher in winter, it may cause your air
conditioning device to work continuously. The set point which causes the device to work continuously
depends on outside temperature, air conditioning device heating and cooling capacity, and some other items
related to your building.
Note: If you set a value much higher than 24°c in summer or much lower in winter, it may cause your air
conditioning device not to start working. For a brief on the conditions which cause such a behavior refer to
the previous note.
2.4.3. Season settings (Menu item 3)
Set the current season for the controller to work properly.
Setting the "summer" in this field causes the controller to switch the air conditioner on if the room
temperature is higher than the desired.
In "winter" mode, the air conditioner switches on if the room temperature is lower than the desired.
Use "Right" or "Left" key to adjust the current season. The result appears at "Season setting" section of the
screen (Refer to section 2.2 to find "Season setting" section of the screen and section 2.1 for "Right" and
"Left" keys).
Notice: Not setting this field correctly may cause your air conditioner not to start working.

3.1. Mounting the digital dimmer unit
The digital dimmer unit is designed to be installed inside the air conditioning apparatus, however, it can also
be installed anywhere near the device while the wiring to apparatus parts would be possible.
There are four ¼ inches holes around the power unit to be used for screwing the power unit to the apparatus.
Use bolts and nuts if you are going to attach the power unit to the air conditioning apparatus, or wall anchors
and screws if you are going to attach it to a wall close to apparatus.
Notice: Screw the digital dimmer unit so that the fins are vertical. Improper installation may impede the air
flow and cause the digital dimmer unit to warm up (Refer to the following diagrams).
Use the wiring diagram at section 3.4 for fastening the wires.
