AIR-TO-WATER HEAT PUMP HEATING SYSTEM 38AW/80AW
■■ Non-ozone depleting R-410A refrigerant:
-- Chlorine-free refrigerant of the HFC group with zero
ozone depletion potential
-- High-density refrigerant, therefore less refrigerant
required
-- Very efficient, therefore gives an increased energy
efficiency ratio (EER)
■■ The new packaging ensures high protection during
transport and handling and is 100% recyclable.
Fast and simple installation and
service
■■ Easy access to all internal components: Unscrew only three
screws to remove the complete front panel to access the
refrigerant piping connections, control box and electrical
connections, as well as the compressor and other key parts.
■■ Advanced circuit design and component selection has
resulted in a compact unit with an exceptionally small footprint that is easy to transport through narrow doors.
■■ Reduced weight and a handle on the unit panels to
facilitate transport.
■■ No additional buffer tank required. This simplies and
speeds up the installation process.
■■ 3-bar pressure relief valve as standard
■■ 8-litre internal expansion tank
■■ High-temperature refrigerant protection
■■ Water flow switch to ensure that the circuits contain
enough water to operate correctly.
■■ Various power cable outlet options: Pre-punched holes in the
cabinet panels permit cable exit on the side, front or rear.
■■ Dealer service tool connection kit includes the software
and connections to monitor the operating parameters
from a personal computer, giving an easy-to-read display
with visual graphs and statistics indicators.
■■ All 80AW units are equipped with 1 inch gas MPT water
connections.
■■ The 80AW comfort module reduces space requirements
and simplifies the installation. Only the power and the water
supply and return piping need to be connected.
■■ Condensate drain piping connection

■■ Advanced technology provides maximum energy-efficiency
with high capacity available at peak conditions and optimised
efficiency at low and mid compressor speeds. The XP Energy
heat pump DC inverter uses Intelligent Power Drive Unit
(IPDU) hybrid inverter technology, combining two electronic
management logics: Pulse Amplitude Modulation (PAM) and
Pulse Width Modulation (PWM) for optimised compressor
operation in all conditions, minimised temperature
fluctuations, and provides perfect individual comfort control
with significantly reduced energy consumption:
-- PAM: Pulse Amplitude Modulation of the direct current
controls the compressor at maximum load conditions
(start-up and peak load), and increases the voltage at
fixed frequency. The compressor works at high speed
to rapidly achieve the desired temperature.
-- PWM: Pulse Width Modulation of the direct current
controls the compressor at partial load conditions, and
adjusts the frequency at fixed voltage. The compressor
speed is fine-tuned and the system provides high-level
comfort (no temperature fluctuations) at exceptionally
efficient working conditions.
■■ Compressor frequency is increased continuously up to
the maximum level. This ensures that there are no current
draw peaks in the start-up phase and safe connection
to a single-phase power supply even in large-capacity
systems. The maximum operating current of XP Energy
systems is below 12 A (systems up to 6.5 kW) and below
23 A for larger systems (up to 11.5 kW). Inverter rampup speed makes soft starts unnecessary and ensures
immediate maximum power.
■■ The two rotary compression cylinders, offset from each
other by 180°, and the DC brushless motor with the shaft
in perfect balance ensure reduced vibration and noise,
even at very low operating speeds. This results in an
extremely wide range between minimum and maximum
capacity with continuous operation, guaranteeing that
the system is always optimised and provides maximum
comfort at exceptionally high efficiency levels.
■■ Twin-rotary cylinders, low vibrations and low load to the
shaft ensure highest compressor reliability and a long
trouble-free operating life.
■■ All DC brushless twin-rotary compressors are equipped
with crankcase heaters as standard.
■■ A double compressor shield for acoustic insulation further
reduces noise levels.

■■ The XP Energy heat pump systems have an extremely high
energy efficiency ratio in both cooling and heating mode,
ensuring significant energy savings. Large and efficient
coils and optimised circuiting feature ensure that all the
combinations meet the European tax rebate efficiency
targets. Efficiency at part-load conditions (seasonal energy
efficiency) reaches the highest level in the industry.
■■ Year-round comfort: The advanced technology used in
the new XP Energy heat pump condensing units provides
optimised comfort levels for the end users, both in terms of
water temperature control and silent operation. The desired
temperature is quickly reached and effectively maintained
without fluctuations. The XP Energy offers optimised
individual comfort levels - both in winter and in summer.
■■ Wide temperature operating range: XP Energy heat pumps
can operate efficiently in extreme temperature conditions.
For end user comfort the units operate down to -20 °C
outdoor temperature in heating mode, and in the summer,
they produce hot water up to 60 °C at up to 30 °C
outside temperature for domestic hot water applications.
■■ Specially shaped anchorage feet ensure correct and safe
fixing of the unit.
■■ The programmable NUI thermostat periodically runs
system checks to monitor and assess the unit operating
parameters. If a problem occurs, troubleshooting fault
codes and messages help the service technician to
identify the fault.
