GENERAL INFORMATION GENERAL INFORMATION
PEAK CUT FUNCTION (OPTIONAL PARTS: UTY-XWZXZ2)

Suppresses maximum capacity and performs energy-saving operation and can prevent breaker
tripping.
This function performs operation by setting a peak current value and reducing the power
consumption.
* Performance drops by reducing the power consumption preferentially.
Level 1 ... Performs operation which suppresses the power consumption to almost 0% by stopping
the compressor.
Level 2 ... Performs operation which suppresses the power consumption to 50% of the rated
power consumption value.
Level 3 ... Performs operation which suppresses the power consumption to 75% of the rated
power consumption value.
Level 4 ... Performs operation which suppresses the power consumption to the rated power
consumption value (100%).

SIMULTANEOUS MULTI SYSTEM1-4.
 IDEAL COMFORTABLE AIR FLOW DISTRIBUTION
Can support various installation
scenes from ofce to commercial
space by same place multi
connection of up to 3 units.
Indoor units distributed layout according to the shape and number
of people and lighting conditions of the room even on wide oors
and atypical oors. Ideal comfortable air ow distribution can be
realized.

ALL DC

ALL DC saves energy throughout the year
z
By making all the motors DC, electricity loss is decreased and power consumption
is substantially reduced. In addition, fan motor high speed rotation is increased and
annual power consumption amount is saved by increasing the airow.
