• Sleep Mode. The function enables the air conditioner to automatically increase cooling or decrease heating 1°C per hour for the first two hours, then holds steady for the next 5 hours, after that it will switch off. This function maintains both energy savings and comfort at night.
• Temperature Compensation. Temperature compensation function eliminates the difference in temperature between the floor and ceiling by mixing the different layers of air. Consequently, the time for cooling the room is reduced, and a cold offset rising stream of warm air by stirring.
• Refrigerant Leakage Detect. Indoor unit shows error code "EC" and stops automatically when refrigerant leakage is detected. This protects the compressor from high temperature damage due to refrigerant leakage.
• Anti-cold Air Function. Indoor fan speed is regulated automatically from the lowest grade to the setting grade according to evaporator temperature when the unit just starts heating operation. This function can prevent cold air blowing out to avoid discomfort to the users.
• Emergency start
• Low Ambient Cooling. With built-in low ambient kit or special designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The air conditioner can run cooling operation even when the outdoor ambient temperature is down to -15°C.
• 1W Standby. Intelligent on-off technology enables Pioneer products automatically enter energy-saving mode when standby, cut energy consumption from normal 5W to 1W or 0.5W per hour which counts 80%~90% of saving.
• 2-way Draining. Both left and right sides of the indoor unit are possible for outstretch of connective piping and drainage hose for easy installation.
• Follow Me (Remote Thermostat). Temperature sensor built in the remote controller will sense it’s surrounding temperature. The unit will adjust the room temperature more accurately to give you comfort.
• 46°F Heating. In heating operation, the preset temperature of the air conditioner can be as low as 46°F, which keeps the room temperature steady at 46°F and prevents the house from freezing when it is unoccupied for a long time in severe cold weather.
• Chassis Heating Belt. Heating belt is fitted on the base plate of the outdoor unit to prevent defrosting water accumulation, which improves heat transfer efficiency.

Optional

• High Density Filter. Compared with ordinary dust filter, the anti-dust effect of this high density filter can increase more than 50%, it can clean dust, pollen up to 80%.
• Wireless Control. With the Wireless control, you can easily turn off each indoor unit that it is paired, outside your home via your smart phone. Furthermore, you can turn it on before you come back.

Q: What is the cooling or heating capacity of this system?
A: This system is perfect for small to medium-sized rooms, such as bedrooms, offices, or living rooms. It can effectively cool or heat an area of about 250 to 350 square feet, depending on insulation and other factors.

Q: Can this unit be used for both cooling and heating?
A: Yes, the Pioneer 9,000 BTU Ductless Mini-Split Inverter++ model provides both cooling and heating functions, making it a versatile solution for year-round comfort.

Q: What makes this model energy-efficient?
A: The 21.5 SEER rating ensures the system is highly energy-efficient, helping you reduce electricity consumption while keeping your space comfortable. The Inverter++ technology also adjusts the cooling or heating power to the room's needs, ensuring maximum efficiency without wasting energy.

Q: Does the unit include the necessary components for installation?
A: Yes, the Pioneer 9,000 BTU Ductless Mini-Split Inverter++ system comes with both the indoor and outdoor units, along with installation components. Professional installation is recommended to ensure proper setup and optimal performance.

• Clean or Replace Air Filters: Clean or replace the air filters every 1-3 months to maintain airflow and system efficiency. Dirty filters reduce performance and energy efficiency.
• Inspect and Clean Coils: Dirty coils can lower the performance of your system. Clean the evaporator and condenser coils every 6-12 months using a soft brush or coil cleaner to ensure optimal heat exchange.
• Clear the Condensate Drain: Check the condensate drain for blockages regularly to prevent water damage and mold growth. Use warm water or a wet/dry vacuum to clear any obstructions.
• Inspect Refrigerant Lines and Insulation: Check refrigerant lines for signs of damage or leaks, and ensure the insulation is intact. Damaged lines or missing insulation can affect the system’s efficiency and cause energy loss.
• Keep the Outdoor Unit Free of Debris: Remove leaves, dirt, or other debris around the outdoor condenser unit to ensure proper airflow and prevent overheating. This will maintain efficient operation.
• Test the System Regularly: Operate your mini-split in both heating and cooling modes periodically to check for consistent performance. If the unit is not working effectively, call a technician.
• Listen for Unusual Sounds: If you hear strange noises such as buzzing, rattling, or hissing, this could indicate loose components, refrigerant issues, or airflow problems. Address these issues with a technician.
• Schedule Annual Professional Maintenance: Schedule a yearly inspection by a qualified technician to check refrigerant levels, clean internal components, and ensure everything is working properly. Regular maintenance will extend the life of your system.
