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.

1. DEFROSTING MODE

When the outside temperature is below 23°F (-5°C), recovery of heat in HRV unit
creates frost in the core. For ERV unit, when the outside temperature is below
14°F (-10°C), recovery of 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

BOOTING SEQUENCE

The unit booting sequence is similar to a personal computer booting
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 AMBER for 10 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.

All units are equipped with an integrated control, located under the unit, on the
recessed side of electrical compartment. Plug the unit.

Use the push button (1) to control the unit. The LED (2) will then show on
which mode the unit is in.

2.2 OPTIONAL MAIN CONTROL VT4W

For more convenience, this unit can also be controlled using an optional
main wall control VT4W. Only one VT4W can be connected to the unit.

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

main control VT4W.

2. If an optional auxiliary control is used, if activated, this auxiliary
control will override the optional main control operation.

When power is applied for the first time or after
a power failure, this control is in OFF mode.
Activate the push button; the light indicator will
show clearly in which operating mode the unit is.
