FEATURES



Improvement of market suitability

z

Considerable improvement of installation work by compact size and light weight considering with

the conditions of installation in the ceiling.

The size which the indoor unit can be installed in the spacing between the beams is required for

the installation in the ceiling.

Restriction for dimension of width and height.

Indoor unit installation example

Correspondence to Network

z

Various networks can be constructed according to the user needs.

1.Fresh air output port

Fresh air is connected with the fan of an indoor unit.

2.Electrical heater output port

Electrical heater operates at the time of heating.

3.External input port

Start / Stop of the air conditioner can be changed from the external equipment.



Room temperature sensor switching

z

Switches from room temperature judgment by room temperature sensor attached to indoor

unit body to room temperature judgment by room temperature sensor attached to wired remote

controller.

Economy operation

z

The power consumption can be reduced.

Powerful mode ...Standard

Soft mode ...Performs operation which reduces the power consumption

Auto restart

Space saving

z

Compact size•

High performance has been realized with a compact indoor / outdoor unit.

Due to the compact size of the indoor and outdoor unit, the installation space required

has been reduced allowing for a wider selection on installation locations.

OUTDOOR UNIT

Low noise mode (Optional parts: UTY-XWZXZ3)

Introduction of a low outdoor noise operation mode allow the outdoor unit to have two quiet mode

operation settings.

* Performance may drop depending on the outside air temperature condition, etc.

Peak cut operation

z

Peak cut mode (Optional parts: UTY-XWZXZ3)

The introduction of a peak power consumption mode control 4 steps outdoor operation control to

cut down energy usage at peak energy usage times.

* Performance drops by reducing the power consumption preferentially.

Level 1 ... Performs operation which suppresses the power consumption to the rated power

consumption value (100%).

Level 2 ... Performs operation which suppresses the power consumption to 75% of the rated

power consumption value.

Level 3 ... Performs operation which suppresses the power consumption to 50% of the rated

power consumption value.

Level 4 ... Performs operation which suppresses the power consumption to almost 0% by stopping

the compressor.
