1. USING THIS UNIT
CAUTION
Before using this unit for the first time, please take the time to carefully read page 2 of this guide to ensure it is
used safely and and properly.
1.1 YOUR VENTILATION SYSTEM
This unit is designed to provide fresh air to your home while exhausting stale, humid air. By eliminating accumulated pollutants and
humidity, it maintains an optimum air quality and an ideal relative humidity. It is equipped with a recovery core that is designed specifically
to control excess humidity and reduce ventilation costs by recovering the heat or energy from the exhausted air, and using that same heat
or energy to warm the fresh air being supplied. This recovery process is accomplished in such a way that the stale air is never mixed with
the fresh air.
When the outdoor temperature is below -5°C (23°F), recovery creates frost in the module. To maintain proper operation, the unit is
programmed to defrost the recovery module. The defrost duration and frequency vary according to the outdoor temperature. After defrosting,
the unit returns to the operating mode selected by the user.
1.2 INTEGRATED CONTROL
Unit Booting Sequence
The unit’s booting sequence is similar to a personnal computer’s booting sequence. Each time the unit is plugged in after being unplugged,
or after a power failure, it will perform a 30-second booting sequence before starting to operate. No command will be taken until the
unit is fully booted.
This unit is equipped with an integrated control, located on its upper left side.
•
Use the integrated push-button (1) to go from OFF to Low Speed, to High Speed, and back to OFF.
•
The color of the LED indicator shows what speed the unit is running in:
•

If a problem occurs while the unit is running, the LED indicator (2) will blink. The color of the blinking
light indicates the type of error detected. Refer to Troubleshooting section.
For more convenience, these units can also be controlled using an optional wall control. When using an
optional control, unit must be set to OFF using the integrated push-button.
For more information about their operation modes, refer to the Main and auxiliary wall control User Guide,
included with the ventilation unit and also available at www.vanee.ca or www.venmar.ca.

6.6 CONNECTING THE DRAIN
CAUTION
A drain tubing (included) must be installed for all HRV units. For ERV units, it is not required, however, it is
recommended for climates where the outside temperature typically remains below -25°C (-13°F), (over a 24-hour
period) for several days in a row, combined with an indoor humidity of 40% or higher.
1.
Connect the plastic tube to the drain fitting located under the unit.
VO0190
2.
Make a water trap loop in the tube to prevent the unit from drawing unpleasant odors from the
drain source. Run the tube to the floor drain or to an alternative drain pipe or pail.
TIE-WRAP
CAUTION
If using a pail to collect water, locate the tube end approximately 1” into the pail
in order to prevent water from being drawn back up into the unit.

7. CONTROLS
7.1 ELECTRICAL CONNECTION TO OPTIONAL CONTROLS
⚠WARNING
Always disconnect the unit before making any connections. Failure in disconnecting power could result in
electrical shock or damage of the wall control or electronic module inside the unit.
CAUTION
Never install more than one optional main wall control per unit. Make sure that there are no short-circuit between
the wires or with any other components on the wall control. Avoid poor wiring connections. To reduce electrical
interference (noise) potential, do not run wall control wiring next to control contactors or near light dimming
circuits, electrical motors, dwelling/building power or lighting wiring, or power distribution panel.
•
•
Use the terminal connector included in the installation kit to perform the electrical
connection for main and optional wall controls.
Make sure all wires are correctly inserted in their corresponding holes in the terminal
block. A wire is correctly inserted when its orange receptacle is lower than another one
without wire. On picture beside, wire A is correctly inserted, but wire B is not.

7.2 SETTING EXTENDED DEFROST
These units are factory set to normal defrost. In cold region (outside temperature -27°C [-17°F] and lower), it may be necessary to setup
extended defrost. During the first 2 seconds of the booting sequence, while the integrated control LED is GREEN, press on push button for
3 seconds to set the unit in extended defrost; the LED will blink AMBER to show the unit is in extended defrost mode. After that, the LED
will shut off, and turn RED (the unit resumes its booting sequence).

7.3 ELECTRICAL CONNECTION TO THE FURNACE
⚠WARNING
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low
voltage class 2 circuit of the furnace blower control.
For a furnace connected to a cooling system:
On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” at the thermostat and
thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERNATE FURNACE INTERLOCK WIRING.

8. BALANCING THE UNIT
PREPARATION
Follow these steps to ensure accurate measurements:
•
Seal all the ductwork with tape. Close all windows and doors.
•
Turn off all exhaust devices such as range hood, dryer and bathroom fans.
•
Make sure the balancing dampers are fully open (their adjusment pin (A) must be vertical,
see illustration aside).
•
Make sure all filters are clean (if it is not the first time the unit is balanced).
•
If the installation is in any way connected to the ductwork of the cold air return of a furnace/air
handler, make sure that the furnace/air handler blower is ON. If not, leave furnace/air handler
blower OFF.
•
If the outside temperature is below 0°C/32°F, make sure the unit is not running in defrost while
balancing by waiting 10 minutes after plugging the unit in.
•
Set the unit to high speed.

2.
3.
4.
5.
6.
7.
8.
Place the magnehelic gauge on a level surface and adjust it to zero.
Connect tubing from gauge to EXHAUST air flow pressure taps (refer to label on unit for
SCREW
gauge connection).
Be sure to connect the tubes to their appropriate high/low fittings. If the gauge drops below
zero, reverse the tubing connections.
Note the CFM value from balancing chart on unit.
Repeat steps 3 and 4, but to FRESH air flow pressure taps.
Using the appropriate adjustable balancing damper, lower the highest value so it matches
the lowest value. A difference up to ±10 cfm is acceptable.
VJ0031
Secure both dampers in place with a fastening screw (included in the hardware kit).
Write the required air flow information on a label and stick it near the unit for future reference (date, maximum speed air flows, your
name, phone number and business address).
