21778 REV. 02
Congratulations!
You have made an excellent choice! The operating principle of your Heat or 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 guide 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
Denotes an instruction which, if not followed, may severely damage the unit
and/or its components.
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.
CAUTION
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
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). At
least once a year, the unit mechanical and electronic parts should be inspected
by qualified service personnel.

REPLACEMENT PARTS AND REPAIR
In order to ensure your ventilation unit remains in good working condition, you must
use Venmar Ventilation ULC genuine replacement parts only. Venmar Ventilation ULC
genuine replacement parts are specially designed for each unit and are manufactured
to comply with all the applicable certification standards and maintain a high standard
of safety. Any third party replacement part used may cause serious damage and
drastically reduce the performance level of your unit, which will result in premature
failing. Venmar Ventilation ULC also recommends to contact a Venmar certified
service depot for all replacement parts and repairs.
1. Defrosting Mode
When the outdoor 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 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.

2. Controls
2.1 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.
2.2 Integrated control
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.
LED COLOR

If a problem occurs during the unit operation, its integrated
control LED (2) will blink. The color of the blinking light
depends on the type of error detected. Refer to Section
4 Troubleshooting on last page for further details.
CAUTION
When using optional main control, the integrated
control must be turned off.
VE0220
2.3 Optional Main and Auxiliary Controls
For more convenience, these units can also be controlled using an optional main control.
Only one main control can be connected per unit.
CAUTION
Turn off the integrated control and wait until its LED is turned off before using an
optional main wall control.
NOTE: If an optional auxiliary control is used, its activation will override the main control
operation.
For more information about your unit controls, refer to the Main and auxiliary wall controls
user guide (included with your unit and also available at www.venmar.ca).

3.2 Annual Maintenance
Do the same operations as the Quarterly Maintenance (Section 3.1), and clean the
recovery core as follows (refer to the core label):
HRV units: Soak the heat recovery core in a mixture of lukewarm water and mild soap.
Rinse thoroughly. Shake the core to remove excess water and let it dry.
ERV units: Remove the dust on the core using a vacuum cleaner and a soft brush
attachment.
After reinstalling the core, the filters and the unit’s door, clean the exterior hoods.
