Samsung MWR-SH11UN - User Manual

This document is a user manual for the Samsung Wired Remote Controller MWR-SH11UN, designed for use with Samsung air conditioners. It provides detailed instructions on the operation, advanced functions, and maintenance of the remote controller.

Function Description

The MWR-SH11UN wired remote controller serves as the primary interface for controlling a Samsung air conditioner. It allows users to select various operating modes, adjust temperature and fan speed, and access advanced features.

Basic Operations:

Auto Mode: Automatically adjusts temperature and fan speed to maximize comfort. It provides strong, cold breeze when the indoor temperature is high and a weaker breeze as it cools down.
Cool Mode: Allows manual adjustment of fan speed, temperature, and air flow direction. If heating operation is selected during cooling, cooling is canceled.
Dry Mode: Effectively removes excess humidity, ideal for rainy days.
Fan Mode: Produces a breeze similar to a powerful fan, without cooling or heating.
Heat Mode: Produces warm air for use in colder seasons. The system may temporarily stop producing breeze at the start to avoid cold drafts. A defrost indicator (snowflake icon) turns on when the outdoor unit is defrosting, during which the indoor unit does not generate breeze. After heating, the air conditioner may produce some breeze to discharge residual heat. If cooling is selected during heating, heating is canceled.

Advanced Functions:

Air Flow Direction (Swing): Allows users to adjust the vertical direction of the air flow by tilting the blade up and down. Pressing the "Swing" button once initiates the movement, and pressing it again stops the blade at the desired position. For duct-type indoor units, this function may not control air flow direction, and a specific lamp will blink.
Quiet Operation: Reduces the noise level of the air conditioner. This mode can be activated by pressing and holding the "Quiet" button for more than 3 seconds. The availability of this function depends on the air conditioner model; if not supported, an icon will blink.
Wind-Free Cooling: Provides a mild, cool breeze through micro-holes on the Wind-Free panel, with the main air flow blade closed, preventing direct cold drafts. The system automatically controls temperature and fan speed based on indoor conditions. It can be used in Cool, Dry, or Fan modes. Recommended set temperatures are 24-26°C (75-79°F). In Fan mode, the compressor stops, providing only mild air circulation for air cleaning. The air flow blades may open intermittently to control air currents depending on installation settings and changes in indoor temperature/humidity.
Long Reach: Delivers a strong air flow over a long distance. This function is activated by pressing the "Long" button. Fan speed cannot be changed in this mode. If the indoor unit is off or does not support Long Reach, an indicator will appear.
Clean Function: Removes moisture from inside the air conditioner to prevent the growth of fungi and bacteria. Activated by pressing and holding the "Clean" button for more than 3 seconds. The operation duration varies from 30 seconds to 20 minutes depending on indoor unit conditions. It continues automatically once started until canceled.
On-Timer: Allows scheduling the air conditioner to turn on at a specific time when the indoor unit is off. Time can be set in 30-minute increments for less than 3 hours, and 1-hour increments for more than 3 hours, up to a maximum of 24 hours.
Off-Timer: Allows scheduling the air conditioner to turn off at a specific time when the indoor unit is on. Similar to the On-Timer, time can be set up to 24 hours.
Sleep Function: Automatically turns off the air conditioner after 6 hours without interrupting operation during the night. The availability of this function depends on the air conditioner model.
Lock Function: Locks the entire display of the wired remote controller to prevent accidental changes. Activated by pressing and holding the "Lock" button for more than 3 seconds. An indicator will be displayed, and other buttons will blink if pressed while locked.
S-Plasma Ion: Eliminates airborne contaminants, allergens, bacteria, and viruses. This function is set or canceled in the user setting mode. If not supported, an icon will blink.
Outing Function: Maintains a minimum cooling or heating temperature when the user is away. If the indoor temperature differs by 5°C (9°F) from the desired outing temperature, the air conditioner will turn on automatically. It operates with low fan speed and is active only when the wired remote controller is off. It repeats for up to 12 hours before canceling. Desired outing temperatures can be set in user settings: Cool mode (25-30°C/77-86°F, default 27°C/81°F) and Heat mode (16-22°C/61-72°F, default 16°C/61°F).
