User manual for the Lessar LZ-KDP remote control

Intellect wall-mounted remote control Lessar LZ-KDP. Operating instructions

One of the main features of LESSAR equipment is the ease of control. For the Home series air conditioners, LESSAR specialists have developed a special remote control with an ergonomic design, named Intellect.

The Intellect control system allows you to select the desired operating mode of the air conditioner, activate any of its numerous functions, and display the main modes on the screen. Logically arranged buttons make operating the air conditioner so simple that even a child can handle it: the remote control is designed on the principle of “grab and use.” At night, the yellow backlight enables operation as easily as during the day, without the need to turn on the lights. The wall-mounting kit ensures convenient storage and keeps it always within reach.

Safety Precautions

➠ Before first use of the remote control, insert the batteries and ensure correct polarity (“+” and “-”) is observed.

➠ Make sure the remote is pointed at the unit and that there are no obstacles between them. The maximum transmission distance is 8 meters.

➠ Do not drop or throw the remote control. Avoid exposure to liquids. Do not expose the remote control to direct sunlight or excessive heat.

➠ If the remote control does not operate properly, remove the batteries for 30 seconds and reinstall them. If this does not help, replace the batteries.

➠ When replacing batteries, do not mix new and old batteries or batteries of different types, as this may cause malfunction.

➠ If the remote control will not be used for a long time, remove the batteries to prevent possible leakage damage.

Additional Warnings:

The device is not intended for use by young children or infirm persons without supervision. Young children should be supervised to ensure they do not play with the device.

Note

This remote control is universal and includes all functional buttons. However, some of them may be inactive depending on the features of your air conditioner. If certain functions are not supported by your air conditioner, the corresponding buttons on the remote will not operate.

MODE

This button is used to select the operating mode. Each press will switch the mode in the following sequence:

AUTO → COOLING → DRY → HEATING → FAN ONLY → (cycle repeats)

❗👉➨ Note: The HEATING mode is not available on cooling-only units.

TEMP/TIME ▲ or ▼

Press the ▲ button to increase the set room temperature or to adjust the timer value clockwise. Pressing the ▼ button will decrease the set temperature or adjust the timer value counterclockwise. The temperature setting range is from 16°C (60°F) to 32°C (90°F).

❗👉➨ Note: Temperature cannot be set in AUTO or FAN ONLY modes; therefore, these two buttons will not function in those modes.

TURBO

In cooling mode, pressing this button switches the air conditioner to maximum power. Pressing it again will deactivate the mode.

SLEEP

Press this button to activate the energy-saving mode. Pressing it again will deactivate the mode. This function is available only in Cooling, Heating, and Auto modes and is intended to maintain a comfortable sleeping environment.

In this mode, the indoor unit maintains the set temperature for two hours, after which it changes the setpoint by 1°C. In heating mode, the temperature is decreased; in cooling mode, it is increased. After another two hours, the indoor unit changes the temperature setting by another 1°C.

After 7 hours of operation (from the moment the “SLEEP” button was pressed), the indoor unit will turn off automatically.

LED (Display Backlight)

Pressing this button will turn the indoor unit’s LED display off or on. When pressed, the display will switch off completely; pressing it again will turn it back on.

SHORT CUT

Used to restore the previous remote control settings.

FAN (Fan Speed)

1. Low → 2. Medium → 3. High → 4. Auto → (cycle repeats)

❗👉➨ Note: AUTO fan speed is not available in FAN ONLY mode.

TIMER ON

Sets the equipment start timer. The first press of the button enters the time setting mode. Each subsequent press will change the set time by 0.5 hours. Holding the button will change the time faster.

If no buttons are pressed for five seconds, the remote will exit the time setting mode, the set time will be saved automatically, and the display will show the ON symbol.

When the set time is reached, the air conditioner will turn on automatically.

Possible operating scenarios:
➠ Start at the set time;
➠ Start at the set time after the unit has been switched off by the timer.

The timer operates within the next 24 hours.

To reset the time, press the TIMER ON button again.

TIMER OFF

Sets the equipment stop timer. The first press of the button enters the time setting mode. Each subsequent press will change the set time by 0.5 hours. Holding the button will change the time faster.

If no buttons are pressed for five seconds, the remote will exit the time setting mode, the set time will be saved automatically, and the display will show the OFF symbol.

When the set time is reached, the air conditioner will turn off automatically.

Possible operating scenarios:

.

Battery Replacement

The wireless remote control requires two LR03-type batteries for operation. Always use batteries of the same type and observe polarity when replacing them.

Slide the battery compartment cover open. Remove the used batteries and insert new ones, ensuring correct polarity.

❗👉➨ ➠ Do not mix old and new batteries after replacement.
➠ If the remote control will not be used for an extended period, remove the batteries.
➠ The remote control’s range does not exceed 8 meters from the indoor unit (with new batteries). Using it at greater distances is ineffective.
➠ If the display does not change or the air conditioner does not respond to button presses, remove the batteries and reinsert them after 30 seconds.

Replace the batteries if the command is not confirmed by a beep or if the display appears dim.

Manual Air Conditioner Start

If the remote control is lost or damaged, the air conditioner can be started in manual mode.

❗👉➨ Attention When starting manually, it is not possible to select the operating mode, adjust the temperature, or change the fan speed; the unit will select these settings automatically.

To start the air conditioner:

➠ On the switched-off unit, press the AUTO button once to start in automatic mode; the unit will select optimal settings on its own.
➠ The next press of the AUTO button will start the air conditioner in cooling mode at +24°C.
➠ To stop the air conditioner, press the AUTO/COOL button once; the unit will turn off automatically.

..
