Variable Evaporation Temperature (VET) for Energy Saving and Comfortable Air conditioning

The indoor and outdoor units work in tandem to control evaporation temperature, refrigerant volume, and airflow. This enables optimal air conditioning according to the number of people in the room and the indoor temperature, as well as energy savings and comfort.

Note: When fan speed is set to Auto.

Variable Evaporation Temperature (VET) for Energy Saving and Comfortable Air conditioning

High Durability

Wide Operating Range

Cooling operation is possible even when the outdoor temperature is as low as -10°C DB or as high as 43°C DB. The remote controller temperature can be set from 18°C up to 30°C*.

*Depending on the type of remote controller.
Note: Cooling capacity depend on indoor/outdoor temperature. Please refer technical databook.

Rust-resistant and Easy to Maintain

The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. Panasonic also uses a copper tube condenser, which makes it easy to repair and maintain. All models are equipped with Blue Fin condenser.

Note: Selecting this unit does not completely eliminate the possibility of rust developing. For details concerning unit installation and maintenance, please consult an authorised dealer.
