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 switches “S1”, “S2” and “S3” of the 441001K3RC, 442001K3RC,443001K3RC (accessory
Fig. 57). The same functionality can be achieved with 441001K3RC, 442001K3RC,443001K3RC or with 3 switches NO.
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.20A or Fig.20B).The front cover LED indicates when the Free cooling mode is on.
The speed increase can be automatically achieved through room sensors like 441079, 442079, 443079,
441068RL, 442068RL, 443068RL or RG1/CO2 sensor, connecting such switch in parallel to the S2 switch.

The accessory 441001K3RC, 442001K3RC,443001K3RC can controll up until 10 units at the same time.

OPERATION
• The device should not be used as an activator for water heaters, stoves, etc., nor should it discharge into hot air/fume vent ducts deriving from
any type of combustion unit. It must expel air outside via its own special duct.
• Operating temperature: -20°C up to +50 °C.
• The device is designed to extract clean air only, i.e. without grease, soot, chemical or corrosive agents, or flammable or explosive mixtures.
• Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
• Do not immerse the device or its parts in water or other liquids.
• Turn off the main switch whenever a malfunction is detected or when cleaning.
• For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance with the wiring regulations, to provide a full
disconnection under overvoltage category III conditions (contact opening distance equal to or greater than 3mm).
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a
hazard.
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return/discharge into/from the room in compliance with existing regulations in order to ensure proper device operation.
• If 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.
STANDARD
External grille in high quality, impact and UV-resistant ABS colour RAL 9010.
WARNING:
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
