Congratulations!
You have made an excellent choice! The operating principle of your Heat 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 guide uses the following symbols to emphasize particular

WARNING
Identifies an instruction which, if not followed, might cause serious personal
injuries including possibility of death.
Denotes an instruction which, if not followed, may severely damage the unit
and/or its components.
!
Make sure at all times that the outdoors 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 the 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 uses 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
CAUTION
NOTE: Indicates supplementary information needed to fully complete an instruction.
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).

1. Defrosting Mode
When the temperature outdoors is below -5°C (23°F), recovery of heat 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 temperature ourtoors.
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.

BOOTING SEQUENCE
The unit booting sequence is similar to a personnal computer boot sequence. Each time the unit
is plugged after being unplugged, or a power failure occurs, the unit will perform a 30-second
booting sequence before starting to operate.
During the booting sequence, the integrated control LED will light up and remain 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
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.
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 which mode the unit is in.
Refer to table below to see how to operate the unit using its integrated control.

DEHUMIDISTAT OVERRIDE SELECTION
In the operating modes MIN, MAX, 20 min/h and RECIRC, the user can select a dehumidistat
override so that if the relative humidity (RH) in the house exceeds the RH setting previously stored,
the ventilation unit will exchange in high speed until the target indoor RH setting is reached.
An air exchanger is not a dehumidifier, but it can change the indoor relative humidity by bringing
in drier or more humid air from outdoors during non heating season. The dehumidistat override
function is useful to reduce indoors RH when the outdoor air is cool and dry during the heating
season. Select a target RH between 30% and 55% according to your comfort. When outdoor
relative humidity is high (e.g. in summer), turn off the override by pressing OK until the RH display
disappears.
When the dehumidistat override is activated, the AUTO indicator will appear on
LCD screen to show that the actual mode is being overridden. Also, the relative
humidity appears (if it was not shown, see example at left). Once the target humidity
level is reached, the unit goes back into its original operating mode and AUTO
disappears from LCD screen.
NOTE: If the actual mode is MAX, only the relative humidity level appears on screen; AUTO label
will not appear.
To engage the dehumidistat override, press OK. The actual indoor RH and the %HUM label appear
on LCD screen.
NOTE: If the actual RH is less than 20%, then the humidity indicator will display “LO”, and if the
actual RH is greater than 80%, then the humidity indicator will display “HI”.
To turn off the dehumidistat override, press OK again. The RH and %HUM display will disappear
from LCD screen.
MAINTENANCE INDICATOR
The maintenance indicator is represented by an M in a rounded
triangle, at the top of the house (see at right). If this indicator is
flashing, perform the regular maintenance (3 months), and if it is not
flashing, perform the annual maintenance (refer to Section 3).
