Condition Rooms Accurately With 3D i-See Sensor™


APG proudly introduces the latest innovation from Mitsubishi Electric Cooling & Heating (Mitsubishi Electric): the CITY MULTI® ceiling cassette indoor unit, featuring the new 3D i-see Sensor (PLFY-EP-NEMU-E).

In comparison to previous generations, the new PLFY ceiling cassette indoor unit features an updated stylish, square-edge design. This sleek and compact unit allows for easy installation. The unit can easily recess into a suspended ceiling, and the corner-pocket design allows access through each of the four corners for any necessary height adjustments or maintenance. In terms of maintenance, the units also have washable filters that provide about 2,500 hours of use in a normal commercial environment before cleaning is needed.

The PLFY also includes a new, powerful component that ensures superior comfort for building occupants and energy saving benefits for building owners and managers: The 3D i-see Sensor. While mounted to the exterior panel of the ceiling cassette, the sensor continuously analyzes the thermal profile of a room, identifying cool and warm spots. To achieve an accurate profile, it performs hundreds of circular scans, continuously monitoring a given space. When a room is occupied, the 3D i-see Sensor scans and identifies heat signatures and applies cool or warm air as needed. For maximum personalized comfort, the sensor may be customized to direct the unit to deliver air toward or away from the occupants. In an unoccupied room, the sensor automatically adjusts the temperature levels and may also be customized to switch to an energy-efficiency mode.

The indoor unit is available in capacities ranging from 8,000 Btu/h to 48,000 Btu/h.

Additional features include:

  • Automatic setback based on occupancy detection
  • 3D turbo fan enabling increased airflow
  • Four fan speed settings including auto-fan
  • Ventilation air intake supported

Designing For Excellence


At the Advanced Products Group (APG), a division of Aireco Supply, Inc., we’re excited to announce that one of our projects, The Dawson-Bailey House, Arlington, Virginia, won the Design Excellence Award at the Mitsubishi Electric Cooling & Heating (Mitsubishi Electric) 2017 Diamond Leadership Conference.

As the oldest structure in Arlington County, The Dawson-Bailey House dates back to the mid-1850s. Originally owned by Thomas B. Dawson, the house is a two-story structure built from stone with interior gable end chimneys and a five-bay front porch. After its use as a tenant house during the Civil War, the county has historically preserved the home. In recent years, the county has transformed the house to serve as a community center. To adapt the two-century-old house into a fully functioning community center while preserving its historical aesthetic, the county selected Mitsubishi Electric VRF.

With our assistance, the home has an R2-Series outdoor unit that connects with two individually zoned ducted units on the first floor. When the relative humidity increases during unoccupied times, one unit can be set in heating mode while the other unit in cooling mode to dehumidify the entire space. The county controls the home’s comfort levels through a SmartME controller and monitors the humidity levels through a Siemens system.

Now with Mitsubishi Electric VRF, the house remains a tangible piece of Arlington’s past while serving as a center for the surrounding community. We’re honored to be involved in this project and excited that it serves as a paradigm for future historic retrofit projects.
