INDOOR UNITS – 4-way cassette 900×900

PLFY-M71VEM6-E Electric Air Conditioner

Ideal for…
New design of 4-way cassette VEM model suits most commercial applications thanks to its elegance and syle. Its peculiar features are horizontal flow function, individually settable vanes and possibility to install 3D i-see sensor for top  environment comfort control.

3D i-see sensor: Temperature sensor
3D i-see sensor is able to detect temperature distribution inside the room, making it possible to direct airflow to those areas which generally receive less air, making them more uncomfortable (too cold or too hot) for users.

**Horizontal flow

**

This new indoor unit is capable of handling five vane positions, making it possible to achieve horizontal flow that spreads across the ceiling, maximizing the Coanda effect. This allows to avoid, if needed, direct airflow to users in the room,  which can sometimes be uncomfortable. 

3D i-see sensor: Direct/Indirect flow function
Optional 3D i-see sensor allows to detect and count users in the environment and their position. User can set either Direct or Indirect flow to occupied areas, with single control on four vanes.

3D i-see sensor: Energy saving
3D i-see sensor features allow to optimize comfort conditions and at the same time achieve energy saving. Thanks to the occupancy sensor the unit is able to automatically handle and reduce power output accordingly to users actually  being present in the room or in certain areas of it. This feature is particularly helpful in those environments in which occupancy varies significantly during the day.

Optimum airflow

2-, 3-, 4-way airflow pattern selection
Three outlet options are available–bidirectional, three-way, and four- way–to suit different types of installation. Select, for example, the four-way pattern for installation in the center of the room and three-way pattern for installation in  the corner.

Individual vane angle settings
Vane direction can be changed or fixed from the remote controller to direct the supply air at or away from objects or occupants in the room.

2-, 3-, 4-way airflow pattern selection + Individual vane angle settings
Combinations with individual vane settings enable an optimal outlet setting for each room layout to ensure even temperature distribution throughout each room. The result is uniformly comfortable air conditioning.

Equipped with high- and low-ceiling modes

Units are equipped with high- and low-ceiling operation modes that make it possible to switch the airflow volume to match the height of the room. Being able to choose the optimum airflow volume helps optimize the breezy sensation felt  throughout the room.

Automatic air-speed adjustment

An automatic air-speed mode automatically adjusts airflow speed to maintain comfortable room conditions at all times. This setting automatically adjusts the air speed to conditions that match the room environment.

Panel and control

The unit is supplied with PLP-6EA panel which does not include signal receiver. This component (PAR-SE9FA-E) can be installed as a corner accessory, as well as 3D i-See Sensor (PAC-SE1ME-E). The unit is compatible with all wired MA and ME remote controls and, if equipped with signal receiver, wireless remote controls. New PAR-SL101A-E is compatible with PLFY-M VEM, and presents numerous new features, such as weekly timer, backlit display, 0,5°C temperature setting and monitoring, as well as functions for 3D i-see sensor (optional).

Connectable to Plasma Quad Connect
The optional Plasma Quad Connect PAC-SK51FT-E can be installed on the indoor units.

Simplified installation

Thanks to new temporary panel supports maintenance and installation operation are now easier for field technicians.

Also, panel weight has been reduced by 20% thanks to a new design.

A simple loosening of support screws allows the removal of the control box and corner accessories.

Electrical box wiring
After reviewing the power supply terminal position in the electrical box, the structure has been redesigned to improve connectivity. This makes complex wiring work easier.

Increased space for plumbing work
The top and bottom positions of the liquid and gas pipes have been reversed to allow the gas pipe work, which requires more effort, to be completed first. Further, through structural innovations related to the space around the pipes, the  area for the spanner has been increased, thus improving liquid piping work and enabling it to be completed smoothly.

What has changed on PLFY-M VEM6-E Cassette Units?

• The physical dimensions of the size 50,63 & 80 has been changed
• High Fan speed airflow has been increased, hence the new Mid1 can be used instead. However, this also depends on the capacity & sound rating of the required space
• Cooling and heating airflow rate on High Fan speed is different on size 50 & 63.
• The optional Plasma Quad Connect PAC-SK51FT-E can be installed on the indoor units
