Unit description
R
AARIA ONE INVERTER
is a climate control system without ex-
ternal unit suitable for wall installation on any perimeter wall.
The aesthetic impact is reduced significantly both on the out-
side where only two 162 mm holes will be visible, and inside the
house thanks to a depth of only 170 mm, smaller than conven-
tional indoor climate control units.
The rotary-type compressor is regulated by the DC-inverter con-
trol with continuous modulation, ensuring high energy stand-
ards. The DC fan motor improves performance and reduces the
noise level. The expansion valve electronically optimises the flow
of refrigerant in the circuit.
Control, adjustment and programming are carried out using the
on-board control or the infrared remote control.

Safety and adjustment devices
The device safety and setting are achieved thanks to:
•
temperature sensor of the upper heat exchanger, transmits
the detected value to the main electronic board which acti-
vates:
—
heating mode if the detected temperature is greater than
52°C, turning off the lower fan which then restarts when
the temperature is lower than or equal to 47°C
—
heating mode if the detected temperature is greater than
62°C for 10 seconds, turning off the compressor which then
restarts when the temperature is lower than or equal to
47°C
—
cooling and dehumidification if the detected temperature
is lower than 0°C for 20 seconds, turning off the compres-
sor and the lower fan that restart when the temperature is
greater than 7°C
•
temperature probe of the lower heat exchanger, transmits the
detected value to the main electronic board which activates:
—
cooling mode if the detected temperature is greater than
58°C, increasing the speed of the lower fan until the tem-
perature is lower than 55°C
—
cooling mode if the detected temperature is greater than
62°C, turning off the unit which then restarts after 60 sec-
onds when the temperature is lower than 62°C
—
cooling and dehumidification mode if the detected tem-
perature is lower than 25°C, forcing the lower fan to oper-
ate at minimum speed
•
temperature sensor of compressor outlet, transmits the value
to the electronic board which acts when the temperature is
greater than 110°C, turning off the unit
•
external air temperature sensor, which transmits the detect-
ed value to the electronic board to act on the unit’s operation
and adapt it to variations in external conditions
•
room air temperature sensor, which transmits the detected
value to the electronic board to act on the unit’s operation
and to adjust the room temperature
•
safety float in the condensation pan that turns off the unit if
the level of condensation is too high

Identification
The unit can be identified through the technical data plate:
12345678
Technical data plate
Contains the device’s technical and performance data.

The tampering, removal, or absence of the identification
plates will not allow the product to be properly identified by
its serial number.
