obtain full benefit from your unit. Over the coming months, you will increasingly appreciate the
feeling of living in a more comfortable house.

CAUTION
Make sure at all times that the outdoor intake and exhaust hoods are free
from any snow during the winter season. It is important to check your unit
during a big snow storm, so it doesn’t draw in any snow. If this is the case,
please operate the unit in the recirculation mode, or turn it OFF for a few
hours.
Do not use your unit during construction or renovation of your house or
when sanding drywall.This type of dust may damage your system.
Since the electronic control system of the unit is incorporated with a
microprocessor, it may not operate correctly because of external noise
or very short power failure. If this happens, unplug the unit and wait
approximately 10 seconds. Then, plug the unit in again.

WARNING
!
CAUTION
When leaving the house for a long period of time (more than two weeks), a
responsible person should regularly check if the unit operates adequately.
If the ductwork runs through an unconditioned space (e.g.: attic), the unit
must operate continuously except when performing maintenance and/
or repair. Also, the ambient temperature of the house should never drop
below 65°F. At least once a year, the unit mechanical and electronic parts
should be inspected by qualified service personnel.

REPLACEMENT PARTS AND REPAIR
In order to ensure your ventilation unit remains in good working condition, you must
use Broan-NuTone LLC genuine replacement parts only. Broan-NuTone LLC genuine
replacement parts are specially designed for each unit and are manufactured to comply
with all the applicable certification standards and maintain a high standard of safety. Any
third party replacement part used may cause serious damage and drastically reduce the
performance level of your unit, which will result in premature failing.Broan-NuTone LLC also
recommends to contact a Broan-NuTone LLC certified service depot for all replacement
parts and repairs.

1. DEFROSTING MODE
4
When the outdoor temperature is below 23°F, recovery of heat in HRV units creates frost in
the core. For ERV units, when the outdoor temperature is below 14°F, recovery of energy
creates frost in the core.
To maintain its proper operation, the unit is programmed to defrost the recovery core. The
defrost frequency varies according to the outdoor temperature.
During the defrost cycle, the dampers of the unit close but the unit speed can be set on high
or low, according to your needs, using the VT9W main wall control. Refer to the Main and
auxiliary wall controls user guide (included with your unit and also available
at www.broan.com) for more details.
After defrosting, the unit returns to the operating mode selected by the user.
2. BOOTING SEQUENCE
The unit and VT9W wall control booting sequence is similar to a personal computer booting
sequence.
Each time the unit is plugged after being unplugged, or a power failure occurs, the unit will
perform a 30-second booting sequence before starting to operate.
During the booting sequence, the unit is checking and resetting the motorized damper
position, while the VT9W wall control screen displays 5%, 10%, 15%, etc. (up to 100%).
Once the motorized damper position completely set, the booting sequence is done.
NOTE: No command will be taken until the unit is fully booted.
3. MAIN AND AUXILIARY CONTROLS
The only main control compatible with these units is the VT9W (purchase separately).
Only one main control can be connected per unit.
Up to five VB60W push button auxiliary controls can be used.
NOTE: When used, the VB60W activation will override
the VT9W operation, as well as the unit defrost cycle.
The chronometer icon appears on VT9W screen as
long as the VB60W is activated.
For more information about your unit controls, refer to the
Main and auxiliary wall controls user guide (included with your unit and also available at
www.broan.com).

fuerte nevada para que no quede hundido en la nieve. Si esto ocurriera,
utilice el aparato en el modo de recirculación o apáguelo durante unas
horas.
No utilice el aparato cuando haya obras de construcción o renovación en
su casa o cuando se estén lijando paneles murales de yeso. Este tipo de
polvo puede dañar el sistema.
Dado que el sistema de control electrónico del aparato lleva un

PRECAUCIÓN
Si no va a estar en la casa durante un largo periodo (más de dos semanas),
un responsable debería verificar regularmente que el aparato funciona
debidamente.
Si las tuberías pasa a través de un espacio acondicionado (p. ej., un altillo),
el aparato debería funcionar constantemente, menos cuando se repare o
