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:
NOTE: Indicates supplementary information needed to fully complete an instruction.
We welcome any suggestions you may have concerning this guide and/or the unit,
and we would appreciate hearing your comments on ways to better serve you.
Please forward all correspondence to us at the address indicated on the product
registration card included with 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 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 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.

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

Controls
BOOTING SEQUENCE (CONSTRUCTO 1.5V AND NOVOFIT 1.0 ONLY)
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 will light GREEN (unit set in
normal defrost) or AMBER (unit set in extended defrost) 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.
BOOTING SEQUENCE (HRV EKO 1.5 AND ERV EKO 1.5 ONLY)
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 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.

ADJUSTING DEHUMIDISTAT
Setting during the summer months:
During this period, unless being afflicted with breathing problems, using the
Dehumidistat 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.
2.5 Constructo Main Control
(for AVS Constructo 1.5V unit only)
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.
