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:

!

WARNING

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

CAUTION

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,

or ways to better serve you. Please forward all correspondence at the address below:

Hartford, WI 53027

CAUTION

Make sure at all times that the outside 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 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.

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 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. 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 Broan-NuTone LLC certified service depot
for all replacement parts and repairs.

1. D EFROSTING MODE

When the outside temperature is below 23°F, recovery of heat or 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 outside temperature.

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

All units are equipped with an integrated control,
located on the upper left side of the unit.

Use the push button (1) to control the unit.

The LED (2) will then show on which mode the
unit is in.

Refer to table below to see how to operate the
unit using its integrated control:

THREE TIMES NO LIGHT

If a problem occurs during the unit operation, its integrated control LED (2)
will blink. The color of the blinking light depends on the type of error detected.
Refer to Section 4 Troubleshooting on last page for further details.

NOTE: WHEN USING MAIN CONTROL, THE INTEGRATED CONTROL
MUST BE TURNED OFF.

2.2 BOOTING SEQUENCE

The unit booting 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 (2 in illustration
below) will light GREEN for 5 seconds, and then will turn RED. During this
RED light phase, the unit is checking and resetting the motorized damper
position. Once the motorized damper position 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. CONTROLS (CONT’D)

2.3 OPTIONAL MAIN AND AUXILIARY CONTROLS

For more convenience, these units can also be controlled using an optional
main control.
Only one main control can be connected per unit.

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

2. If an optional auxiliary control is used, its activation will override the main
control operation.

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).
