• I f the environment in which the product is installed also houses a fuel-operating device
(water heater, methane stove etc., that is not a "sealed chamber" type), it is essential
to ensure adequate air intake, to ensure good combustion and proper equipment
operation.
• I nstall the product so that the impeller is not accessible from the air outlet side as
verified by contact with the Test Finger (test probe "B" of the norm EN61032) in
compliance with the current safety regulations.
INTRODUCTION
Quantum HR is a single alternate flow decentralized (single point) residential heat recovery
unit, also called «push&pull» unit, designed to ensure adequate ventilation in enclosed
environments without energy losses.
It is recommended that two units are installed in pair: when one unit is pulling, the other
is pushing.
Pair of units can be installed in the same room or in different rooms (i.e. livingroom and
bedroom). The unit is suitable for installation on an outside wall.
The unit should operate continuously, and only stopped for maintenance or service.
When heat exchange is not useful (for example in mid-seasons when indoor and
outdoor temperatures are similar), or when heat exchange is not recommended
(for example with the option "summer free cooling"), it is recommended to set
the unit in "extract-only" or "intake-only" mode and NOT to switch it off.
TECHNICAL SPECIFICATIONS
• I nner ventilation unit material: high quality, impact and UV-resistant ABS colour RAL 9010.
• D esign front cover removable for cleaning without the use of tools.
• E asy maintenance installation plate, for easy access to the heat exchanger from inside
the room.
• A nti-dust filter, easily removable for washing by the user without tools.
• R egenerative honeycombs ceramic heat exchanger.
• E xternal grille in high quality, impact and UV-resistant ABS colour RAL 9010 (STANDARD
version) or external hood in aluminium, painted in white RAL 9010, acoustically lined
(PRO version).
• H igh efficiency aerodynamic fan with "winglet" blades to optimise quietness and efficiency.
• S ingle phase EC reversible Brushless motor with integral thermal protection.
• M otor mounted on high quality ball bearings.
• T he unit is double insulated: no earth connection is required.
• T rickle speed selectable.
• B oost mode.
• F ree-cooling (Bypass) mode.
• I PX4 degree of protection.
• P ower supply 220V to 240V~ 50Hz.
VERSIONS
STANDARD External grille in high quality, impact and UV-resistant ABS colour RAL 9010.
PRO External hood in aluminium, painted in white (RAL 9010), acoustically lined.
OPERATION
In both versions, the unit pulls air out for 70 seconds, then it pushes air in for the same time.
When heated air is pulled (extracted) from inside the room, it warms up the heat exchanger;
when the cold air is pushed (supplied) in the room, it gets preheated, recovering most of

thermal energy which would be otherwise lost in the ventilation process.
The unit runs at the speed selected by activating the two-position switches "S1", "S2"
and "S3" of the CTRL-S (accessory fig. 64). The same functionality can be achieved with
CTRL-S or with 3 two-position switches.

S3 switch activates the "Free cooling " (Bypass) mode , which stops alternate flow and
keeps the fan in "extract-only" or "intake-only" mode, to avoid the heat exchange when
necessary. To set the extract-only" mode or "intake-only", place the integral jumpers as
per fig. 21A-21B).The front cover LED indicates when the Free cooling mode is on.
An automatic "Boost"mode can be achieved through a dedicated switch or room sensors
like SEN-HY, SEN-PIR or SEN-CO2, connecting such switch in parallel to the S2 switch.
Wiring diagram of one unit: fig. 19A.
Wiring diagram with ambient sensors: fig.19B and fig. 19C.
Wiring diagram of two or more units: fig. 19D.
Ensure that the electric wiring to L and N is done correctly; an incorrect
connection will lead to malfunction or permanent damage of the fan
SyNCHRONISATION
When the units are installed in pair, they must be synchronised so that when one unit is
extracting, the other is supplying, and viceversa.
This is achieved by setting the dedicated jumper (fig. 21A-21B)
RESET OF THE SYNCHRONISATION
OPTION 1
If two or more units are connected under the same main switch, to reset the synchronisation,
the main switch must be switched first OFF and then ON to reactivate (fig. 38)
OPTION 2
If two or more units are not connected under the same main switch, to reset the
synchronisation, press at the same time the black pin of each unit (fig. 40) for at least
3 seconds.
SyNCHRONISATION IN CASE OF INSTALLATION WITH CONTROLLER
If two or more units are controlled by means of the same controller (CTRL-S or similar),
they always operate in a synchronised way. Wiring diagram as per fig. 19D.

jUMPER POSITION
2,2
Intergal jumper set in position A (fig. 21A) means "extract-only" mode.
4,5
Intergal jumper set in position B (fig. 21B) means "intake-only" mode.
The jumper position defines both the air-flow direction when the unit is activated for the
first time (for the synchronisation) and the air-flow direction of the free-cooling mode.
MAINTENANCE AND SERVICE
Maintenance can be carried out by the user as indicated at page 28.
Service must be perfmormed only by technically qualified personnel in accordance with
local rules and regulations. Make sure that the mains supply to the unit is disconnected
(page 29).
Cleaning of the heat exchanger can be performed from outside as well.
