This document is the Owner's Manual for TECO Split-Type Room Air Conditioners, specifically models TWS-TSO26HFFT and TWS-TSO71HFFT. It provides comprehensive information on the safe operation, features, and maintenance of these units.
Function Description:
The TECO Split-Type Room Air Conditioner is designed to provide cooling, heating (for heat pump models), dehumidifying, and fan-only ventilation for indoor spaces. It operates by drawing in air, filtering it, and then cooling, heating, or dehumidifying it via a heat exchanger before circulating it back into the room. The unit offers various operating modes to suit different environmental conditions and user preferences.
Important Technical Specifications:
While specific technical specifications like power consumption, cooling/heating capacity, and dimensions are not detailed in this manual, it does provide operational temperature ranges:
- COOL Mode: Room Temperature >17°C, Outdoor Temperature -7°C to 43°C.
- HEAT Mode: Room Temperature <30°C, Outdoor Temperature -7°C to 28°C.
- DRY Mode: Room Temperature >6°C, Outdoor Temperature -7°C to 43°C.
The remote controller uses 2 LRO 3 AAA (1.5V) batteries. The unit's design and specifications are subject to change without prior notice for product improvement.
Usage Features:
Remote Controller:
The air conditioner is primarily controlled via a remote controller, which features a liquid crystal display showing various symbols for different modes and settings. Key buttons and their functions include:
- TEMP UP (△) / TEMP DN (▽): Adjusts temperature or time settings.
- ON/OFF: Starts or stops operation.
- FAN: Selects fan speed (auto/low/mid/high).
- TIMER: Sets auto-off or auto-on timer.
- SLEEP: Activates the "SLEEP" function for comfortable nighttime operation.
- ECO: In cooling mode, increases temperature by 2°C from the setting; in heating mode, decreases temperature by 2°C from the setting.
- MODE: Selects operating mode (COOL, HEAT, DRY, FAN, FEEL).
- TURBO: Activates "Super" function for rapid cooling (16°C, high fan speed) or heating (31°C, high fan speed).
- SWING: Activates/deactivates movement of deflectors for airflow direction.
- DISPLAY: Switches the LED display on/off.
- MUTE: Activates/deactivates mute function.
- I FEEL: Activates the "I Feel" function, where the remote control measures the temperature at its current location and sends this signal to the air conditioner to optimize the temperature around the user. This function operates for 2 hours and deactivates if the temperature exceeds 0~50°C.
Indoor Unit Display:
The indoor unit features an LED display with indicators for:
- TIMER: Lights up during Timer operation.
- SLEEP: Indicates SLEEP mode.
- Temperature display / Error code (88): Shows the set temperature or malfunction codes.
Emergency Function:
In case the remote controller malfunctions, an emergency button on the indoor unit can be used:
- One press: Initiates forced COOLING operation.
- Two presses (within 3 seconds): Initiates forced HEATING operation.
- Press again: Switches off the unit.
After 30 minutes in forced operation, the unit automatically switches to 23°C cooling mode with auto fan speed.
Operating Modes:
- COOLING Mode: Cools the room and reduces air humidity. Temperature and fan speed can be adjusted.
- HEATING Mode: Heats the room. Temperature and fan speed can be adjusted. During heating, the appliance may activate a defrost cycle (2-10 minutes) to clean frost from the condenser.
- FAN Mode: Operates in ventilation only. Fan speed can be set to low, medium, high, or auto.
- DRY Mode: Reduces air humidity for comfort. Activates alternating cooling cycles and air fan automatically.
- FEEL Mode (Automatic): Automatically sets fan speed and temperature based on the room temperature (sensed by the indoor unit).
- < 20°C: Auto temp 23°C (Heating/Fan)
- 20°C~26°C: DRY, Auto temp 18°C
-
26°C: COOL, Auto temp 23°C
- SLEEP Mode: Automatically adjusts temperature for comfortable sleep. In cooling/dry mode, temperature rises by 1°C every 60 minutes for a total rise of 2°C over 2 hours. In heating mode, temperature gradually decreases by 2°C over 2 hours. The unit switches off automatically after 10 hours.
Airflow Control:
The air outlet direction is motorized for up and down movement (flaps) and can be manually adjusted for left and right movement (vertical deflectors). Some models may have motorized vertical deflectors. For optimal cooling, flaps should be horizontal; for heating, they should be downward. Manual adjustment of deflectors should only be done when the appliance is switched off to prevent damage.
Safety Precautions:
The manual emphasizes several safety precautions:
- Immediately turn off and disconnect power if abnormal situations (e.g., burning smell) occur.
- Do not insert objects into air inlet/outlet.
- Avoid using flammable sprays near the unit.
- Do not operate near combustible gases or in wet rooms.
- Avoid prolonged direct exposure to cool air.
- Supervise children around the unit.
- Ensure proper ventilation if used with other heating devices.
- Turn off and unplug the unit during storms or extended periods of non-use.
- Ensure proper water condensation drainage.
- Do not operate with wet hands.
- Do not climb or place objects on the outdoor unit.
- Avoid long periods of operation with open doors/windows or high humidity.
Electrical Warnings:
- Use only the specified power cord; replace if damaged.
- Keep power plug clean.
- Unplug by holding the plug, not the cord.
- Do not modify power cord length or use extension cords.
- Do not share electrical outlets with other appliances.
- Ensure proper grounding during installation.
- Follow all wiring standards and the Installation Manual for electrical work.
- Ensure tight cable connections and secure clamping.
- Arrange wiring properly to allow the control board cover to close securely.
- All wiring and disconnection must comply with wiring rules.
Maintenance Features:
Antidust Filters:
- Open the front panel.
- Remove the air filter.
- Clean the filter with water; use warm water (max 45°C) if soiled with oil.
- Dry in a cool, dry place.
- Reinsert the filter and close the front panel.
Electrostatic and deodorant filters (if installed) are not washable and must be replaced every 6 months.
Heat Exchanger Cleaning:
- Open the front panel fully and unhook it from the hinges.
- Clean the indoor unit with a cloth, water (max 40°C), and neutral soap. Avoid aggressive solvents/detergents.
- For the outdoor unit, remove leaves and debris, and clean dust with an air jet or water.
End of Season Maintenance:
- Disconnect the automatic switch or plug.
- Clean and replace filters.
- Operate the conditioner in ventilation mode for a few hours on a sunny day to dry the inside of the unit completely.
Replacing Batteries (Remote Controller):
- Slide off the battery cover on the back of the remote controller.
- Insert two LRO 3 AAA (1.5V) batteries, observing polarity (+ and -).
- Slide the cover back into place.
Replace batteries when the display is no longer legible or no confirmation beep is heard. Do not use rechargeable batteries. Dispose of old batteries in designated collection points.
Troubleshooting:
The manual includes a troubleshooting guide for common issues and error codes displayed on the indoor unit:
- E1: Indoor temperature sensor fault (RUN lamp flashes once).
- E2: Indoor pipe temperature sensor fault (RUN lamp flashes twice).
- E6: Indoor fan motor malfunction (RUN lamp flashes 6 times).
Other issues covered include strange odors, noise of running water, mist from the air outlet, strange noises, insufficient airflow, and unresponsiveness to commands. It advises to switch off the air conditioner and cut power immediately if strange noises, faulty electronic control board, faulty fuses/switches, spraying water/objects inside, overheated cables/plugs, or strong smells occur.
