1.0 YOUR UNIT AND ITS PURPOSE
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.

ERV: Units equipped with a heat and humidity recovery core (enthalpic core)
can reduce ventilation costs in winter as well as in summer.
1. During the heating season, the unit draws the humidity and heat from the
stale air and transfers them, in part, to the cold air entering the house, thus
avoiding dryness problems and providing maximum comfort.
In order to preserve the structure of the enthalpic core, the unit will only
exchange 20 minutes per hour when the temperature drops under -15°C
(5°F).
Example
(in winter) :
1.3 RECOVERY
5
HRV: Units equipped with a heat recovery core (polypropylene core) are
specifically designed 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) :
OUTSIDEINSIDE
STALE AIR TO OUTSIDE 4°C/40°F
FRESH AIR TO BUILDING 18°C/64°F
FRESH AIR FROM OUTSIDE 0°C/32°F
STALE AIR FROM BUILDING 22°C/72°F
VF0011
2. During the cooling season, the unit reverses the process, preventing the
humidity from the outside air from entering into the house.
Example
(in summer with air conditioning) :

FRESH AIR TO BUILDING 27°C/80°F
FRESH AIR FROM OUTSIDE 32°C/90°F
STALE AIR FROM BUILDING 25°C/77°F

When the outside temperature is below 0°C (32°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. Defrosting lasts 6 minutes. 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.

Location: Located in the busiest area of the house.
Purpose: To adjust air supply and reduce condensation on windows.
ADJUSTING THE AIR SUPPLYCONTROL
a) Select speed “MIN.” or “MAX.” using
switch A(as shown on diagram).
• When “MIN.” (minimum speed) is
selected, if the knob Bis 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 he knob Bis set below of above the click.
b) To turn the unit off, place selector Aat the “OFF” position.
Optional controls, however, may still be active.
ADJUSTING THE CONDENSATION CONTROL
Setting during the summer months:
Normally there is no condensation on your windows during this period which
therefore eliminates the need of the condensation control for a few months. Set
knob Bat the “SUMMER’’ positon during this period.
Setting during the fall, winter and spring months:
1) Determine the humidity level in your house (bring the knob Bcounterclockwise
to -20°C, then bring it back clockwise slowly until you hear a “click”).
2) Set knob Ba notch under this temperature level or “click”.
NOTES: 1. Do not select a temperature below -20°C. This could lead to excessive
dryness in the air causing discomfort for the occupants.
2. When the humidity level is high, the unit automatically operates at
maximum speed. If you change the setting of your “AIR SUPPLY”
knob (B) at that time, it will remain at maximum speed until the
humidity level is reduced, and then switch to the desired setting.
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) within few hours). In that case, we suggest waiting a few days
to allow the situation to stabilize.

2.3 USING THE VALUE MAIN CONTROL
Location:Located in the busiest area of the house.
Purpose: To adjust air supply and reduce condensation on windows.
ADJUSTING AIR SUPPLYCONTROL
a) Press “PUSH” (A) until the “MIN.”, “MAX.” or “INTERMITTENT” light
indicator appears.
• When “MIN.” (minimum speed) is
selected, if the knob Bis 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 he knob Bis
set below of above the click.
• Select “INTERMITTENT” (20 minutes minimum speed exchange every
hour) when you are away from the house for a few days or when you
deem the inside air too dry.
b) To turn the unit off , press “PUSH” (A) until the “MIN.”, “MAX.” and
“INTERMITENT” light indicators are all turned off.
NOTE: Optional controls will still be active. (Indicator (C) will be the only one to
light up if an optional control is active).
ADJUSTING CONDENSATION CONTROL
Setting during the summer months:
Normally there is no condensation on your windows during this period which
therefore eliminates the need of the condensation control for a few months. Set
knob Bat the “SUMMER’’ positon during this period.
Setting during the fall, winter and spring months:
Ideally, maintain humidity level within the “Comfort Zone” (between 5°C and
-20°C), which is the dark area around knob B.
To reduce humidity level, turn knob B clockwise a notch below the click. The unit
will then switch to high speed, lighting up the humidity light (Dindicator).When
this light goes "OFF" (after a few hours or a few days), repeat the same procedure
if excess humidity persists.
NOTE: If the air is too dry, set your knob B back to the “Comfort Zone” and use
INTERMITTENT or turn off the unit.
When the humidity light (Dindicator) goes "ON", you can still change the
mode of operation but your change will take place only when the light goes OFF.

TYPE OF PROBLEM TRY THIS...
1 Nothing works. • See if the unit is plugged in.
• See if the unit is receiving power
from the house circuit breaker or fuse.
2 All light indicators on the wall control • Unplug the unit, wait 30 seconds,
are flashing then reconnect. If the problem
(every 8 seconds). continues, contact your installer.
3 Noisy unit. • Clean the fan assembly (see
Section 3.2). If the problem continue,
contact your installer.
4 Condensation on windows. • Adjust the humidity control knob as
(Air too humid.) per instructions (see Section 2).
• Operate the unit at maximum speed
(MAX.) during activities generating
excess humidity (family gatherings,
extra cooking, etc.).
• Leave curtains half-open to allow air
circulation.
• Store all firewood in a close room with
a dehumidifier or in a well ventilated
room, or store the wood outside.
• Keep the temperature in your house
above 18°C (64°F).
5 Air too dry. • Do not adjust your humidity control
below -20°C (-4°F).
• Operate the unit at low speed (MIN.).
• Temporarily switch to the intermittent
mode.
• Temporarily use a humidifier.
6 Air too cold at the air supply grille. • Make sure the outside hoods are not
blocked.
• Operate the unit at low speed (MIN.).
• Have the system balancing checked.
• Have the unit defrost system checked.
• Install a duct heater.
If the problem persists, contact your installer at the telephone number and
address indicated on the first page of this manual or call for your local distributor.
4.0 TROUBLESHOOTING
If you think your unit is malfunctioning, check some of the following.
