1.3 Unit description
R AARIA START is a heat pump outdoor unit that can be cou-
pled to indoor units of the same series for the air-conditioning
of small/middle-sized rooms. Designed for outdoor installation,
it is suitable for use in residential and small business premises.
The rotary-type compressor is controlled via DC-Inverter control
with continuous modulation from 20% to 110%, thus ensuring
high energy standards. The fan DC motor improves performance
and sound comfort. The expansion valve electronically optimises
the flow of refrigerant within the circuit (excluding AARIA START
25).
1.4 Safety and adjustment devices
The device safety and setting are achieved thanks to
— compressor motor thermal protection, which is triggered in
case the current consumed by the compressor is excessive
— gas delivery temperature sensor, which transmits the de-
tected value to the electronic board that is triggered in case
of overtemperature (110°C)
— anti-freeze sensor, which transmits the temperature value
as detected by the heat exchanger to the electronic board
that is triggered when the heat exchanger is clogged by
frost formations
— suction temperature sensor, which transmits the detected
value to the electronic board that is triggered in order to
adjust the flow of refrigerant gas or to stop the unit in case
of overtemperature (40°C)
— outdoor air temperature sensor, which transmits the de-
tected value to the electronic board that is triggered in or-
der to adjust the operation of the unit indoor components
to the variation of weather conditions
