PLEASE READ AND SAVE THESE INSTRUCTIONS

INSTALLER: LEAVE THIS MANUAL WITH HOMEOWNER

Congratulations!

You have made an excellent choice! The operating principle of your Heat Recovery Ventilator

or your Energy Recovery Ventilator will give you personal comfort you have never known

before.

We have prepared this User Guide especially for you. Please read it carefully to ensure you

obtain full benefit from your unit. Over the coming months, you will increasingly appreciate the

feeling of living in a more comfortable house.

Please take note that this manual uses the following symbols to emphasize particular

information:

Identifies an instruction which, if not followed, might cause serious

personal injuries including possibility of death.

Identifies an instruction which, if not followed, may severely damage the

unit and/or its components.

NOTE: Indicates supplementary information needed to fully complete an instruction.

We welcome any suggestions you may have concerning this guide and/or the unit, and we

would appreciate hearing your comments on ways to better serve you.

Please forward all correspondence to us at the address indicated on the product registration

card included with this guide.

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

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).

4. MAINTENANCE

Refer to illustration below to identify the inner parts of your unit (unit door removed to ease

understanding).

always disconnect the unit from its power source. When cleaning the unit,

it is recommended to wear safety glasses and gloves.

personal desconocido.

Este manual del usuario ha sido preparado especialmente para usted. Léalo atentamente

para sacar el máximo partido del aparato. En los próximos meses agradecerá cada vez más

la sensación de llegar a una casa más confortable.

Con el fin de hacer hincapié en determinada información, en este manual se emplean los

siguientes símbolos:

ADVERTENCIA

PRECAUCIÓN

Compruebe siempre que la toma exterior y las bocas de aspiración estén

libres de nieve en invierno. Es importante verificar el aparato en caso de

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

microprocesador, el aparato podría no funcionar correctamente debido al

ruido externo o a una breve interrupción de la alimentación eléctrica. Si

esto ocurriera, desenchufe el aparato, espere unos 10 segundos y vuélvalo

a enchufar.

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

se limpie. Asimismo, la temperatura ambiente de la casa nunca debería

bajar de 65°F. Le aconsejamos que un técnico especializado examine las

piezas mecánicas y électrónicas del aparato al menos una vez por año.
