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:
NOTE: Indicates supplementary information needed to fully complete an instruction.
We welcome any suggestions you may have concerning this guide

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.
CAUTION
Make sure at all times that the outside hood is 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 (if available), or turn it OFF for a few hours.
Do not use your HRV or ERV 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.

When the outside temperature is below -5°C (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.

BOOTSEQUENCE
The unit boot sequence is similar to a personnal computer boot sequence. Each
times 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 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.

2.2 Optional Main Controls (cont’d)
ADJUSTING AIR SUPPLY CONTROL
1) Select speed «MIN» or «MAX» using
slide switch (A).
• When «MIN» (minimum speed) is
selected, if the knob (B) is set above
the click, the unit will exchange in low
speed with the outside and if it is set
below the click, the unit will exchange
on high speed with the outside until
the desired humidity level has been
reached.
• When «MAX» (maximum speed) is selected, the unit will exchange on
high speed with the outside either if the knob is set below or above the
click.
2) To turn off the unit, slide the switch at the «OFF» position.
ADJUSTING HUMIDITY CONTROL
Setting during the summer months:
During this period, unless being afflicted with breathing problems, using the
humidity control is unnecessary. Set the slide switch to «OFF». (Do not
exchange in day time; exchange at night time, if cool outside, or if it is not raining.)
Setting during the fall, winter and spring months:
(When severe condensation appears on windows)
1) Determine the humidity level in your house (bring the knob (B) counterclockwise
to its maximum position, then bring it back clockwise slowly until you hear a
«click»).
2) Set the knob to one line under this temperature level or «click».
It is possible (and normal) to experience condensation on your windows
when drastic changes in temperature happen (for example: -5°C [23°F]
to -20°C [-4°F]). In that case, we suggest waiting a few days to allow the
situation to stabilize.
CAUTION
Do not select a temperature below -20°C (-4°F).This could lead to excessive
dryness in the air causing discomfort for the occupants.
