Technology overview – Compressor – PAM+PWM technology
AIR HP combines two electronic management logic
control systems
PAM : Pulse Amplitude Modulation
PWM : Pulse Width Modulation
Goal: maximum power at the start up
and in peak load conditions
Goal: maximum efficiency and comfort
Benefit: fast reach of the set point
(desired temperature)
Benefits: energy saving + no temperature
fluctuation once obtained the set
temperature
How: frequency is fixed and voltage is
increased. Compressor works at high
speed to rapidly achieve the set point
How: load voltage is fixed and frequency is
varied to fine tune compressor speed
When: in max load conditions
When: in partial load conditions
Result: HIGH POWER
Result: HIGH EFFICIENCY

Sensors
Several sensors placed in key positions on the
refrigerant circuit electronically detect the
operational state of the system.
A Micro Controller Unit receives the inputs from the
sensors, elaborates them using advanced algorithms
and optimizes the refrigerant flow and the
functioning of core components: compressor, fan
motors and the pulse modulation valve.

Controls – Internal safeties
Several routines are built-in in the PCBs so to grant at any time the best
working conditions of all the components and to protect both the machine
and the installation while maximising the comfort for the user.
-MAIN and ADDITIONAL pump anti-seizing function
-Room anti-freeze function
-Compressor Short Cycling Protection (Timeguard): to protect the compressor form
short cycles and too often on/off. The maximum allowed number of cycles every hour
is SIX
-Minimum Compressor Run Time: to protect the compressor form short cycles and too
often on/off. The compressor is forced to work for a minimum of three minutes even if
in the meantime the heat request has stopped
-Water anti-freeze protection: should the water in/out the plate heat exchanger go
below a certain value, the compressor is stopped
-Water over-temperature protection: should the water in/out the plate heat exchanger
go over a certain value, the compressor is stopped
-Water anti-frost protection due to outdoor temperature. The trace heater, the water
pump, the machine are turned ON in sequence according to the probes readings.
-Discharge temp release control: compressor protection due to over-temperature of
the refrigerant temperature reading.
-Current release control: compressor protection due to over-current absorbed

- compressor warm up procedure: it warms up the compressor to avoid a slackness of
refrigerant inside the component. The procedure is monitored and stopped reading the
current absorption
- defrost control on the fanned heat exchanger, so to grant constantly the efficiency of

Units don’t contain lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls (PBB), or PBDE.
WEEE (2003/108/EC)
Units must be collected separately after its use is completed, and cannot be
disposed as unsorted municipal waste. Objectives:
• to tackle the fast increasing waste stream of electrical and electronic
equipment,
• to increase recycling of electric & electronic equipment (“EEE”),
• to limit the total quantity of waste EEE (“WEEE”) going to final disposal.
The crossed out wheeled bin symbol that is affixed to the product means that
this product falls under the Directive. The user is responsible for returning
the product to the appropriate collection facility, as specified by your
municipality or the distributor.
In case of installation of a new product, it may be possible to have the
distributor pick up old WEEE directly. The producer, importer and distributor of
are responsible for collection and treatment of waste, either directly or through
a collective system.

Schemes examples
In the following slides there are a few installation schemes with the purpose to give a
flavour of the different possible installations of the machine inside a (new or renovated)
system.
It is important to notice that there is the need for the installer to complete the system
with a handful of components, among which the most important is probably the WATER
FILTER.
It is in fact extremely important to avoid that any dirt, metal shavings, sludge, dirt end
up in the plate heat exchanger, to avoid its seizing.
