1. Your Climaset .
Climaset SDT 3/3-ir/3x/3x-ir are designed to work in conjunction with ceiling type horizontal room fan
coils/ducted fan coils to maintain the room/building air condition at the comfort level. Each of the mentioned
models consists of the following units:
Wall mounted unit
Remote controller (Optional, SDT 3-ir/SDT3x-ir)
2. Wall mounted unit .
The wall mounted unit has the following functions:
1. Measurement of room temperature.
2. Interaction with user to adjust the set points.
3. Interaction with the remote controller (SDT 3-ir / 3x-ir only).
4. Interaction with fan coil to adjust the desirable fan speed.

2.2. Screen elements
Room temperature: Indicates the current room temperature.
Desired temperature: Your desired room temperature.
Power status:
Air conditioner apparatus is on.
Air conditioner apparatus is off.
Season setting:
The device is adjusted to work in summer.
The device is adjusted to work in winter.
Fan 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.
Auto: This icon appears if the "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 to the desired temperature the fan speed reduces. The feature is called "smooth approach"
and is only available in SDT 3x/3x-ir.
Animated 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.
Status 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)

1. Fan speed
2. Desired temperature
3. Season settings
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 will be switched
off. It switches on again by pressing the "Right" key.
Notice: Pressing the "Right" key while the maximum fan speed is selected enables the"Auto" mode (SDT
3x/3x-ir 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 the 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
factors 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 desired.
In "winter" mode, the air conditioner switches on if the room temperature is lower than 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.
2.4.4. English / Local (Menu item 4)
It indicates language of the items of the status bar. If "English" is selected, all menu functions will appear in
English. If local is selected, all menu functions of the status bar will appear in your local language.

2.5. Back light
Pressing any keys on the wall mounted unit turns on the back light for several seconds. It enhances reading
during the night.
3. Remote controller unit (SDT 3-ir / 3x-ir only) .
The remote controller utilizes infrared light waves to send the commands to the wall mounted unit. The light
waves are effective at the maximum distance of 16 meters. The viewing angle for the remote controller is 30
degree. It means the wall mounted unit can still sense the commands even if remote controller deflects up to
30 degree from the wall mounted unit infrared sensor.
Note: All remote controllers use the same code, so you may use a single remote control with several wall
mounted units.
Notice: Blocking the infrared lamp on the top of remote controller significantly reduces the range.
3.1. Installing batteries for remote controller
Locate the small latch on the battery compartment cover and push gently the latch in the direction of the
arrow as illustrated below.
The cover releases. Lift off the cover to reveal the inner battery compartment.
Install two new AAA-size 1.5-volt alkaline, lithium or NiCad batteries with correct polarity following the
illustration inside the battery compartment.
Warning: Mixing different battery types may cause explosion. Install same battery types each time you change
them.
Replace the battery cover by inserting the prong into the slot at the bottom of the battery compartment and
then pushing the cover until the latch snaps closed.
