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

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.
