Energy Smart | GENERAL FEATURES
The Sabiana Energy Smart units are high eciency
ventilation units with heat recovery, designed for
residential applications.
The units replace the exhaust air of indoor environments
with outdoor ltered air by means of a high eciency
ePM155% - F71.
The hexagonal counterow heat recovery unit prevents
any winter heat drops due to the introduction of fresh air,
thereby recovering up to 92.5%2of the extracted heat and
conveying it to the clean air introduced in the occupied
environment. Each unit is also equipped with an average
(ePM10 50% - M5) eciency lter3installed on the inlet
of the extraction section to prevent any dust from getting
into the equipment.
All Energy Smart units comply with the 2018 eciency limits imposed by Regulation
1253/14.
The Pro versions are equipped with an automatic centralized air ow control system
operated by an integrated humidity sensor located in the extraction air duct. If the humidity
of the indoor environment exceeds the reference parameters, to prevent the proliferation of mould
and pathogenic bacteria, the fresh air ow is increased with the aim of restoring a healthy humidity
level. The control also prevents from dropping below excessively low humidity levels, thus preventing
excessively dry conditions inside the environments and, as a result, any health hazards. The units are
NOT able, by themselves, to lower the level of internal humidity to a value below that of the outdoor
humidity. All the units can be controlled by means of a supervisory system in accordance with the
following protocols:
• Modbus, with direct access to the dedicated RS 485 web gateway
• Konnex, with KNX interface board (optional)

The range can be classified according to the
installation and control types:
• Pro unit with automatic centralized control via
humidity probe:
• ENY-SP (vertical)
• ENY-SHP (horizontal-vertical)
• Standard unit with time programming control:
• ENY-S (vertical)
ENY-SP and ENY-S units are designed
for vertical wall installation or,
with the addition of feet, floor installation.
Instead, ENY-SHP units are ideal
for both horizontal ceiling installation
and vertical wall installation.
The width of the ENY-SHP and ENY-S units
is such as to ensure easy insertion
into modular kitchen components,
since the width is less than 600 mm.

The Pro Versions are available in class A + while the Standard versions are in Class A. Both
are equipped with high eciency backward-curved blades and EC motors, driven by the
integrated inverter control board for variable speed control.
All units have a remote control user interface (T-EP control),
tted in the frontal panel of ENY-SP and ENY-S units; it is
also possible to disconnect the interface from the frontal
panel and place it on the wall using a special cable.
The Pro versions are Passivhaus certied and
are equipped with a centralized automatic ow rate
control system, that works not only in accordance with
a built-in humidity sensor, but also in response to CO
measurements. In this case, it is recommended to connect
a 0-10V COsensor to the main control board, available on
the market.
For more details about centralized control see chapter at page 64.

The units with automatic control via humidity or COsensor can enable the “AUTO” mode. In this
mode, the fan speed is controlled by an automatic control cycle relating to internal instantaneous
humidity and COvariations. In variable-ow automatic control mode, the user can still intervene at
any time by changing the fan speed manually as required.
The automatic mode will be restored at the next signicant variation of ambient humidity or concen-
tration of CO.
In the event that the user does not require automatic control but just simply time programming or
even manual control, standard units are ideal.
There is a choice of 8 weekly programs for these units: 4 preset programs and 4 free programs that can
be modied as required. The operation can be selected in various intervals of the day, at one of the
four standard speeds, or at the hyperventilation speed “Party”. At any time, the user may force the
programming manually, which will resume at the beginning of the next time interval.
In manual mode, in addition to the nominal speed, there are 3 default speeds equal to 70%,
45%, and 25% of the project ow rate. The timed intensive ventilation modes can be activated
via the user interface (“Party” mode) or via a remote switch located in a particular room (“Booster”
mode).

All the units are equipped with an automatic
bypass system that totally disables use of the heat
recovery unit to permit 100% free-cooling (or
free-heating). The system is controlled by logic sub-
ject to the feedback of the integrated temperature sen-
sors.
Also, the units have the following integrated control
logic:
• The mass supply ow dened by the user is kept
constant in all outdoor climatic conditions.
• The extraction ow is kept at a constant balancing
percentage compared to the air supply ow, in order
to preserve the desired overpressure or negative
pressure for all operating conditions.
When installing the units in homes located in regions with particularly harsh climatic conditions1,
we recommend installing the units with integrated lament electric heaters (E versions), where
the thermal power is continuously modulated to maintain exhaust air at the desired temperature,
preventing freezing2. For all models, it is possible to use an external antifreeze coil, with continuous
modulation.
To prevent excessive eciency drops due to lter clogging, it is recommended to replace the lters at
the end of the recommended period (usually every 6 months). The increase in lter dirt in fact leads
to increased fan rotation resistance, causing a signicant drop in ow rates. With regard to ENY-S units,
the automatic constant ow control system (standard for the ENY-SP units), which prevents any drops
in ow rates due to lter clogging, is available as an accessory. In this case, lter clogging may result in
a signicant increase in power consumption of the fans.
If the ows need to be inverted, all vertical units are reversible during installation (except
for versions with electric heater).
For each model, a complete set of Accessories is also available to meet any installation need.

Energy Smart Horizontal and Vertical Units: ENY-SHP
The Energy Smart horizontal units are
available in three sizes ENY-SHP-150,
ENY-SHP-170 and ENY-SHP-270, in
the Pro version only, that means they
are equipped with an automatic
centralized air ow control system
operated by an integrated humidity
sensor located in the extract air duct;
the 150 and 170 sizes are Passivhaus
certied. The units are ideal for both
horizontal ceiling installation and
vertical wall installation.
The SHP - 150 is distinguished by its extremely compact dimensions that make it easy to install in a
false ceiling. The unit is equipped with a tted control panel, that lets the calibration and activation of
the unit.The Energy Smart SHP-150 unit can be connected to theT-EP remote control panel accessory
to activate the following additional functions:
• Party Mode.
• Holiday Mode.
• Free-Cooling Mode: a single supply air ow to activate manually.
• There is a choice of 8 weekly programs for these units: 4 preset programs and 4 free programs that
can be modied as required.
• Fan speed regulation by means of the T-EP touch pad by selecting one of the 3 default speeds
equal to 70%, 45%, and 25% of the project ow rate.
The SHP - 170 size, like the Energy Smart Pro vertical units, is equipped as standard with a T-EP
control panel.The ENY-SHP 170 is equipped with a motorized bypass system with a double damper,
that totally disables use of the heat recovery unit to permit 100% free-cooling (or free-heating)
automatically. The ENY SHP-170 is also available with integrated lament electric heaters (E version),
in which the thermal power is continuously modulated to keep the exhaust air at the desired
temperature, thereby preventing any freezing.
