ABOUT THIS MANUAL / PRODUCT

The purpose of this manual is to help you with the use of your unit. Please read every section as
they contain important information.

In simplifying explanations, all drawings (illustrations) in this manual show the unit installed in the
“normal” position. However, please note that your unit can be installed in either the “normal” or
“reverse” (upside down) position.

We welcome any suggestions you may have concerning this manual 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’s registration card included with this manual.

This manual uses the following symbols to emphasize particular information:

!

WARNING

Identifies an instruction which, if not followed, might cause serious personal
injuries including possibility of death.

CAUTION

Denotes 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.

Finally, we want to congratulate you on your purchase of this excellent unit which will allow you and
your family to enjoy fresh air throughout your home for years to come!

CAUTION

Some activities create dust or vapors which may damage your unit. You must
therefore turn off and unplug your unit in the following situations:

• Major renovation work • Sanding (e.g. gypsum joints, etc.)

• Housing construction • Varnishing
During very heavy snowstorms or rain with strong winds, the unit should also

be turned off to avoid problems caused by snow or rain entering the unit, even if
it is equipped with an anti-gust intake hood.

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 18°C (65°F). At
least once a year, the unit mechanical and electronic parts should be inspected
by qualified service personnel.

REPLACEMENT PAR TS AND REPAIRS

In order to ensure your ventilation unit remains in good working condition, you must use Broan­NuTone LLC genuine replacement parts only. The 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. Also, Broan-NuTone LLC recommends to contact a certified
service depot for all replacement parts and repairs.

1.2 PURPOSE OF THE VENTILATION SYSTEM

Your ventilation system is designed to provide fresh air, warmed outdoor air to your home while
exhausting stale, humid air from your home. By eliminating accumulated pollutants and humidity, it
maintains an optimum air quality and an ideal relative humidity.

1. YOUR UNIT AND ITS PURPOSE (CONT’D)

1.3 RECOVERY

Your ventilation system is equipped with a heat recovery core that is designed specifically to control
excess humidity and reduce ventilation costs by recovering the heat energy from the exhausted air,
and using that same heat energy to warm the fresh air being supplied. This heat recovery process
is accomplished in such a way that the stale air is never mixed with the fresh air.

EXAMPLE (IN WINTER)

Stale air to outdoors

6°C/42°F

Fresh air to building

16°C/61°F

OUTDOORS

Fresh air from outdoors

0°C/32°F

VF0026

Stale air from building

22°C/72°F

1.4 DEFROST MODE

When the outdoor temperature is below -5°C (23°F), heat recovery creates frost in the module.
To maintain proper operation, the unit is programmed to defrost the recovery module. The defrost
frequency varies according to the outdoor temperature. Defrost lasts 7 minutes (or 10 minutes if set
on “Extented Defrost”). During the defrost cycle, the unit shifts to maximum speed and the dampers
close.

After defrosting, the unit returns to the operating mode selected by the user.

2. CONTROLS

2.1 INTEGRATED CONTROL

These units are equipped with an integrated control, located on the
electrical compartment. Use the push-button (1) to control the unit.
The LED (2) will then show on which mode the unit is in.

NOTES: 1. The integrated control must be turned OFF to use an

optional main control.

2. If an optional auxiliary control is used, if activated, the

auxiliary control operation will override the optional
main control operation.

2.2 BOOT SEQUENCE

The unit boot sequence is similar to a personnal computer boot sequence. Each time the unit is
plugged after being unplugged, or after a power failure, the unit will perform a 30-second booting
sequence before starting to operate. During the booting sequence, the integrated control LED will
light GREEN or AMBER for 5 seconds, and then will shut off for 2 seconds. After that, the LED will
light RED for the rest of the booting sequence. During this RED light phase, the unit is checking and
resetting the motorized damper position. Once the motorized damper position is completely set, the
RED light turns off and the booting sequence is done.

NOTE: No command will be taken until the unit is fully booted.

2.3 OPTIONAL MAIN AND AUXILIARY CONTROLS

For more convenience, these units can also be controlled using an optional main wall control. Many
models can be used, but only one main wall control can be connected to the unit.

NOTES: 1. The integrated control must be turned OFF to use an optional main control.

2. If an optional auxiliary control is used, if activated, the auxiliary control operation will

override the optional main control operation.

For more information about the available controls and their operation modes, refer to the Main
and auxiliary wall control User Guide (included with the ventilation unit and also available at
www.broan.com)
