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.
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. At least once a
year, the unit mechanical and electronic parts should be inspected by
qualified service personnel.

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

2. CONTROLS
This unit is equipped with an integrated control located
under the electrical compartment of the unit. Use the push
button (1) to control the unit; the LED (2) will then show
which mode the unit is in (see illustration at right and table
below).
2.1 BOOTING SEQUENCE
The unit booting sequence is similar to a personal 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 defrost control LED will light 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 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.
NOTE: The integrated control must be turned OFF to use an optional main control.
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.
