Extraordinary Energy-Saving Performance

Extraordinary Energy-Saving Performance
The operation efficiency has been improved using a highly efficient R410A refrigerant, a DC Inverter compressor, a DC motor, and a heat exchanger design.

Energy Savings Design

1. Panasonic’s inverter compressor to improve partial-load capacity.
2. 2 pieces of the printed circuit board for easy maintenance.
3. Large-size accumulator to maintain compressor reliability for extended max piping length.
4. DC fan motor for optimum air volume.
5. Newly designed fan blades to inhibit air turbulence and increase efficiency.
6. Redesigned heat exchanger & copper tubes to increase efficiency.
7. Centrifugal oil separator improves oil separation efficiency and reduces refrigerant pressure loss.
Energy Savings Design

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.

Demand Response Ready

Simple Demand Response

Featuring inverter control technology, LE1, LE2 series systems are Demand Response Management (DRM) ready. With this control, power consumption at times of peak load can be set in three steps to deliver optimum performance. This helps to correspond with the local power management for reducing peak power consumption, and to reduce annual power consumption with minimal loss in comfort.
*Demand controller. Relay contact point: No voltage relay.
**Current input is DC 24V 10mA Use a very small electric current contact point for the relay.
Simple Demand Response

Flexible Demand Response

A maintenance remote controller for service and special connection wiring are required for setting up the outdoor unit after installation of the kit, please contact your dealer for details.
Flexible Demand Response

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 46°C DB. As for heating operation, it is possible even when the outdoor temperature is as low as -20°C WB. The remote controller temperature can be set from 18°C up to 30°C (cooling), 16°C up to 30°C (heating)*.
*Depending on the type of remote controller.
Note: Cooling/heating capacity depend on indoor/outdoor temperature. Please refer technical databook.
Wide Operating Range

Rust-resistant and Easy to Maintain

Corrosion-resistance treated for exposure to rust to assure long-lasting performance. The anti-corrosion Blue Fin treatment of the heat exchanger provides greater resistance against corrosion. Specific models with suffix “E” have this treatment. (Blue Fin treatment is applied to the condenser of the heat exchanger on all models.) Panasonic also uses a copper tube condenser, which makes it easy to repair and maintain.
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.
