(1) Test Condition: Data refers to conditions and parameters as required by the DOE requirements governing this type of product.
HEATING MODE: outdoor ambient temperature DB 47°F/8.3°C WB 43°F/6°C; Indoor environment DB 70°F/21°C - WB 60°F/15.6°C COOLING
MODE: outdoor ambient temperature DB 95°F/35° C BU 75°F/24°C; Indoor ambient temperature DB 80°F /26.7°C - WB 67°F / 19.4°C
(2) Maximum capacity achieved with Power Pro Boost inverter technology. Openings of 8 inches in diameter are recommended for full capacity and
efficiency. Alternatively, it is possible to use openings with a diameter of 6.4 inches, however there is a corresponding loss of capacity and efficiency
that can vary according to the specific application.
(3) The CEER is calculated according to the ANSI RAC-1 2015 standard. The Combined Energy Efficiency Ratio (CEER) is a standard that measures
efficiency of the unit when it is in standby and when it is cooling a space.
(4) The test conditions for the acoustic assessments are conducted according to the DOA classification, carried out in the acoustic chamber at a distance
of 6.5 feet (2 meters). The minimum noise values are detected only in fan only mode.
(5) STC and OITC are calculated by an independent third party in accordance with ASHRAE standards .

2.5.3 SILENT (quiet) mode
This mode can be selected from the infrared receiver (button B3)
or from the serial port and can only be used in combination with
the cooling or heating modes. When the quite cooling mode is
activated, the outdoor fan and the Indoor fan are forced to run at
low speed. The compressor is forced to operate at a fixed
frequency set (default 40Hz) and Tset is automatically increased
by 1° C after 1 hour and by a another degree after 2 hours
(starting from the activation of any function or subsequent
modification of the Tset).
All the cooling subprograms are still enabled, in this way the
outdoor fan can be switched to higher speeds if required by the
usual algorithm.
When the quiet heating mode is activated, the outdoor fan and the
Indoor fan a to run at low speed. The compressor is forced to
operate at a fixed frequency set via IPM EEPROM ADDR1F6
(default 40Hz) and Tset is automatically reduced by 1°C after 1
hour and by a further degree after 2 hours (starting from the
activation of a function or subsequent modification of the Tset).
All heating subroutines are still enabled.
In cases where the low noise mode is deactivated, Tset is
changed from the remote control, the unit is placed in standby
mode or the power is cut off, the operation timer is reset and Tset
is reset to the last received value from the remote control.
In this condition all the foreseen malfunction warnings are
enabled.
2.5.4 ECO Mode
This mode can be selected from the infrared receiver (button B8)
or from the serial port; no message appears on the display. The
IPM board already includes HIGH VOLTAGE limits, which refers
to the total voltage absorbed by the power and IPM boards and
their accessories: maximum voltage limit in cooling mode (e.g. 7
Ampere)
maximum voltage limit in heating mode (e.g. 7 Ampere)
If Economy mode is activated, a lower voltage limit is introduced:
The percentage (%) of the voltage limit is set to 50%.
Example:
5 Ampere x 50% = 2.5Ampere
In order not to exceed 2.5 Amps, the compressor frequency is
limited.

WARNING
DANGER OF ELECTROCUTION
Before carrying out any maintenance or cleaning,
disconnect the appliance from the power supply.
ALL electrical connections and wiring MUST be
done by a qualified electrician and in compliance
with local regulations.
Failure to follow these instructions can cause
damage to property, personal injury
It can be used both as a window contact (on off of the appliance
based on the opening / closing of the contact) or as an ENERGY
BOOST function.
Based on the setting of the PI parameter, it is possible to select
whether and which of the functions are to be activated.
The input located on the terminal (Y2) of the main board can be
used to activate the ENERGY BOOST or SY-STEM ENABLE
functions of the air conditioner.
Configuration and use of the ENERGY BOOST or SYSTEM
ENABLE input:
–Insert the plug into the socket to power the air conditioner then
make sure it is in stand-by mode.
–On the control panel, press the MODE button for more than 10
seconds, until an acoustic signal is emitted.
–The display shows parameter P0.
