Panasonic’s Ductless Mini-Split Air Conditioner & Heat Pump products offer wide versatility in solving your cooling and heating requirements for a single or multiple rooms. The Indoor wall unit (evaporator) is enclosed in a handsome space saving cabinet. It is connected to the outdoor unit (condenser) via refrigerant lines & inter-unit wiring through a 3-1/2” opening in the wall. Since no ductwork is required, installation is simple, fast & efficient.

Flexible Indoor Unit Combinations

Systems with indoor units ranging from 6900 BTU to 24000 BTU are available, ready to provide optimal efficient cooling and heating for rooms of various sizes. The indoor units have been uniquely designed to provide Whisper Quiet operation while delivering comfort throughout the room(s). Panasonic Ductless Split Systems bring together sleek styling in wall, duct or ceiling mounted systems with quality & reliability you can count on

Inverter Technology

Panasonic's inverter provides optimum power control and extremely efficient operation by changing the power supply frequency. The result is speedy, flexible operation using less electricity.



  Microprocessor-Controlled Operation

Microprocessor control ensures that the temperature and humidity levels in the room are always comfortable.


Wireless Remote Control

Panasonic’s infrared Remote Control with and easy to read LCD Display, gives the user the capability to adjust & set temperature, sweep (louver control), fan speeds, timer and more, for complete automatic operation.



Dry Mode

By coupling compressor and fan operation, intermittent operation can be precisely controlled according to room temperature, so that air is efficiently dehumidified.



3 Fan Speeds and Automatic Fan Operation

Convenient microprocessor control automatically adjusts fan speed to High, Medium or Low. According to room temperature to maintain a comfortable airflow throughout the room.



Air Sweep Control

The air sweep function moves the louver up and down in the air outlet, directing air in a “sweeping” motion around the room and providing comfort in every corner.



Louver Control

Louver can be manually set to the desired angle by remote control.




Automatic Heating and Cooling Changeover

After setting the temperature and functions you desire, just relax. If the room temperature is higher than the set temperature, cooling operation begins. If the room temperature is lower than the set temperature, heating operation begins. During normal thermostat cycle operation, cooling and heating operations automatically change in accordance with set temperature, time and room temperature. (Single Zone Heat Pump unit only)




1-hour OFF Timer

When this button is pushed either while the unit is operating or while it is stopped, the unit will operate for one hour and then switch off automatically.



24-hour Clock with ON/OFF Program Timer

The remote control unit allows you to set a wide variety of timer-based operations. Such functions include automatic ON/OFF with a timer setting, same time ON/OFF every day, ON timer, OFF timer and Combination timer.




Night Setback Mode for Cooling and Heating

Cooling and DRY Mode: With the Night Setback Mode, the air conditioner automatically raises the setting temperature 2°F after 30 minutes, and then another 2°F after the next 30 minutes. Heating Mode: With the Night Setback Mode, the setting temperature is automatically lowered 4°F after 30 minutes, and then another 4°F after the next 30 minutes. This saves energy without sacrificing comfort and is ideal for gentle cooling and heating.




Automatic Restart Function after Power Failure

This feature allows the system to automatically resume operation at its preset program, after power is restored from a power failure.




Hot Start Heating System
