Panasonic’s Ductless Split Heat Pump products offer wide versatility in solving your cooling and heating requirements for a single or multiple rooms.


The Indoor unit(evaporator) is mounted inside the room, 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 duct-work is required, installation is simple, fast & efficient. The indoor unit has 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 whisper quiet operations, quality & reliability you can count on.


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.

Self-Diagnosing Function
Details of previous warnings are stored and can be verified on the liquid crystal display. This makes it easier to diagnose malfunctions, greatly reducing service labor. (Wired remote controller)

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)

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.

Hot Start Heating System
Right from the start, air is warm and comfortable. The Hot Start Heating System prevents any cold blasts at the beginning while the heat pump is warming up. (Heat pump unit only)

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.

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.

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.

Electric Refrigerant Control Valve
The circulation volume of the refrigerant is controlled by a pulse type electric control valve. In order to attain optimum efficiency, when the power is switched ON, the opening degree of the electric control valve is controlled between 90 and 480 steps.

This refrigerant blend has been the industry choice for being friendlier to the environment

Quiet Mode
LOW, low fan speed for extra quiet operation.
